Hi Joon,

Thank you for the feedback and thank you to everyone else that has responded. I responded to many of you directly, but this topic has come up a few times so I wanted to address it with the whole group.

We historically have not noticed this phenomenon on the contact aligner, although we have not run that SPR220 process with an etch in a few years. That is another experiment we are planning but have not done so yet.

We will have some SEMs of these particular sidewalls this week, but we do have SEM x-sections of other recent samples and I can confirm that the side walls are directionally angled usually with a slope differential of ~5?. We have worked with Heidelberg a lot on this issue and have it mostly solved, but it is still somewhat visible on thicker resists. The problem was actually much, much worse with negative resists (nLOF2020 or nLOF2070) where the slope variation was so extreme that one side of the pattern would be undercut, while the other positive. Attached is an example of the "poor" profile prior to the fix, along with the more recent "improved" profile.

Heidelberg was able to fix the alignment well enough that we were happy with our negative resist profiles but we have not been able to get it perfectly orthogonal. So we know that the light is slightly angled coming in, but I am still unsure why this would lead to the etch issues that we are seeing.

Thanks,
-Dave

Hello Mr. Hollingshead,

When you did optical lithography with contact mask aligner, SPR220 and S1827, did you get the similar result such as only one side residue?
Have you checked the cross-section in SEM after develop before etching? If there is a directional problem in MLA150, you may observed the difference in side angle in SEM. You may also check sidewall corner residue under darkfield microscope, too.
I think that you had better break down and narrow down the cause and result step by step.?

Good afternoon everyone,

?

We have recently run into some very ?interesting? (completely perplexing) issues while trying to etch some III-V samples in our ICP. Essentially we are seeing some sort of residue on the protected regions of the devices after stripping the resist. Whatever it is, the material seems to also be affecting our etch profiles. The odd part is that the residue has a clear directionality to it and in the present case only appears on two edges. This has led us to believe that is must in some way be a result of some non-uniform / ?angled? exposure from our MLA150. While I can completely understand differing etched sidewall slopes or skewed features if the resist sidewalls are not uniform on all sides, I am having difficulty understanding how this might cause the residue we are seeing (especially in a positive resist). 

?

Any thoughts or possible explanations would be greatly appreciated.

?

Attached are some microscope and SEM images of what we are seeing. I have plenty more I?d be happy to share with those that may be interested!

?

A few relevant processing notes:

???? 
????* All etches were done using a BCl3/Ar chemistry in our Plasmatherm 770 system
????* ~18-20 minutes of etch time, total depth of ~2.5-3.0?m
????* We have repeated these issues on InGaAs device samples as well as bulk GaAs test samples
????* Issue repeated with both SPR220 and S1827 resist masks (both were un-hardbaked, but this is also something we are going to look into)
????* Exposures seem to be properly dosed, but we are planning an etch test on a dose/defocus array to see if exposure has any effect
????* All resist removal was done in 80C NMP
????* We have attempted some follow-on O?2 plasma etches, that seem to remove the material, but it is very slow

?

Thanks,

-Dave

Hello Alex,

I have had 2 cryo pumps refurbished and purchased 1 refurbished helium compressor and 1 refurbished cryo from Bay Technologies. Tim Valdivia is incredibly responsive and very helpful. He is also very knowledgeable and helps troubleshoot cryos and compressors over the phone. I highly recommend them. All three cryos and the compressor are still running 24/7 since 2017.

I have always relied on Austin Scientific (now part of Trillium) for
aftermarket and their own brand of cryo pumps and service.
They were having supply chain issues on some items, but hopefully that
has eased.

Instructors Needed: Electronics, Manufacturing, and Applied Optics
Stonehill College is looking for instructors for its Photonics Certificate Program. This program, which will begin its third year in the fall is intended to train technicians for work in the photonics industry.  The program consists of a sequence of general manufacturing and electronics courses, followed by several optics and photonics courses, with emphasis on hands-on work and on skills relevant to the photonics industry.  These 12-14 week-long courses are in-person, weekday evenings, and there is no expectation of prior background in math, electronics, or industry for the students in the program.
The ideal instructors would have both industry experience and some background in worker training or higher education. The courses place heavy emphasis on hands-on experience (use of machine tools, design and fabrication procedures, etc.), but some of the courses are also expected to cover background in areas such as basic math and software skills. Safety protocols will be strongly emphasized in all courses, and online OSHA-10 and laser safety training is required of the students as part of the program. Classes will be capped at 20 students, and students range in ages from late teens to early 50's with different levels of education and experience.
The courses that we expect to need instructors for in the coming year are:

  *   Electricity and Electronics - Fall semester 2022
  *   Tools and Testing  - Fall semester 2022

(Covers basic measurements with oscilloscopes, calipers, microscopes, etc., as well as practice in welding and other basic electronics and manufacturing skills.)

  *   Digital Fundamentals - Spring semester 2023
  *   Statistical Process Control - Spring semester 2023
  *   Tools and Materials - Spring semester 2023

(Introduction to manufacturing systems, design of engineering processes, and CNC manufacturing)

  *   Applied Optics - Summer semester 2023
  *   Fiber Optics - Summer semester 2023
The 12-month program includes an internship with a local company during the final semester and was constructed with extensive input from local companies. The goal is to prepare the students for immediate employment once the certificate is completed, and the program achieved 100% success in placing students from the first graduating class.
Stonehill College is a private, liberal arts college in Easton, MA, about 20 miles south of Boston, and is committed to diversity in its student body and in its instructors.
More information about the program is available at: www.stonehill.edu/photonics<http://www.stonehill.edu/photonics>.
For further information about the program or the available positions, please contact Profs. Cheryl Schnitzer, Ruby Gu, or David Simon at cschnitzer at stonehill.edu<mailto:cschnitzer at stonehill.edu>, ggu at stonehill.edu<mailto:ggu at stonehill.edu>, dsimon at stonehill.edu<mailto:dsimon at stonehill.edu>.

Hello everyone,

The laser shielding cover of our KLA Tencor D600 profilometer was cracked. Has anyone bought a replacement cover from a 3rd party or made one before? The official replacement is way too expensive for us to afford.

The laser in the profilometer is Class IIIa, 635nm and 5mW, but it doesn?t seem to be easy to find shield plastic plaques for this wavelength. The original cover looks like dark brown colour. Any idea of what material I can choose or which vendor that I can contact?

Thank you!

rapid-prototyping to iterate and push the boundary of technology in our
field.



In particular, we are looking for people with cleanroom experience to work
with patterning and process engineering of nanometer and micrometer
features, deposition, and etching of thin films, metrology, and process
documentation. Experience with the Raith e-beam systems and resists is a
plus. As this is a very hands-on culture, we are currently looking for
on-site full-time engineers to work in/with our new cleanroom being built
near Pasadena, CA. You are an even better fit if you have experience with
python and other programming languages to leave a trail of automation.
Successful candidates will work with cross-functional teams of IC
designers, PCB, and embedded designers, optical engineers, physicists, and
chemists. As we solve each engineering hurdle in front of us, we move on to
the next, and with that, there is a lot of room for growth. The evolution
of job roles at PL&H is as open as your interests and capabilities.



Preferred candidates should have an MS or PhD in electrical engineering,
material science, applied physics, or related fields. We offer the usual
benefits: health insurance, dental and vision, 401k with matching,
relocation expenses, alongside a competitive salary and equity stakes in
the company, plus daily lunches with an engaging discussion. Extraneous
interests in plants (carnivorous or not), DIY, jet engines, telescopes, and
baking bread are a bonus!

Hi all,
   I have found myself in search of a new vendor for our high temperature
profile thermocouples, used in our Tempress furnaces  systems. I would like
to find one that has the capability to reclaim the metals from our non
functioning thermocouples to be used in manufacturing new ones. Tempress
can supply us with new ones but they can't reclaim the old ones. Any leads
would be greatly appreciated.

Thanks....Terre

Greetings to All,
I am writing because we are being challenged, like everyone, to reduce our cost for research. We are considering other options for our Nitrogen gas source including a Nitrogen generator due to the recent cost increase of LN2. We are currently using a 2-tank system which supplies both the liquid and gaseous nitrogen to our facility.
We are averaging 80 to 90 SCFM of utility nitrogen and 6 -7 SCFM of High Purity Nitrogen. We would continue to maintain our liquid nitrogen supply.

Please provide your positive and negative experiences with Nitrogen generators as well as the manufacturer of the unit. All comments/suggestions are welcomed.  Thanks in advance for your input.

Hi All

I'm looking for a set of electrical schematics for a Nanonex NX-2600 NanoImprint tool.
The drawer sensors seem to be working, the chamber moves into the closed position and the lid closed switches are working.
The software waits for the lid to close but eventually aborts.
I chased the wiring to a control card on the rear panel.  Without the schematics I don't know what signals I'm expecting to see through the lid switches.

Any help would be appreciated :)

We have N2 supply via a generator. We supply both High purity and Ultra High purity N2 to our labs. The installation of an N2 generator will greatly reduce you LN2 cost but will have a large upfront cost as we have 2 N2 delivery(hard piping) structures in place. I would have to go through some historical data that is decades old to get you numbers but a it all depends on use. Best guess is a couple years out on ROI but it is a no brainer if you are a heavy N2 user.

I worked in the industrial gas industry for 25 years and Nitrogen generators
are a reliable source of nitrogen for many customers. Usually Nitrogen
generators can provide a range of purity suitable for most industrial
applications..the purity usually is higher when the unit is operated at
lower flow and purity is lower at higher flow rates. For UHP applications
you would likely need an add on purifier to remove O2, H20. If your UHP
process is sensitive to other contaminants (CO,CO2, THC) there are some
purifiers to remove these as well. There are two main types to
consider----membrane based units and adsorbent bed units. 

 

A Nitrogen generator will not provide Liquid N2 and so any operations that
require cryogenic temperatures that LIN provides would not be amenable to
generated N2.

Hello Richard,

At MNMS Cleanroom in MechSE at UIUC, we used www.onsitegas.com<http://www.onsitegas.com> to purchase a 99.9995% n2 Gen. They were cheaper for a better purity and flow rate than Parker. It's overkill for most of our N2 needs, but it's cheaper to supply 99.9995% to everything than to have both low and high purity N2 lines running around the facility. OnSiteGas sales team was great. We did have one issue during install. We used a SS flex hose to supply compressed air to the N2 Gen. This caused the system to "ring" every time it generated N2. I recommend using the really simple rubber hose onsitegas provides to connect from CDA to N2Gen to minimize vibration and resulting noise.

The maintenance is super simple. Just a few compressed air filters on a regular schedule. Approx $500 a year. As long as the N2Gen has compressed air, it pumps out nitrogen.

This was our sales rep. I'm not sure if he's still there.

Subject: [labnetwork] Is Nitrogen Generator a Viable Option

Greetings to All,
I am writing because we are being challenged, like everyone, to reduce our cost for research. We are considering other options for our Nitrogen gas source including a Nitrogen generator due to the recent cost increase of LN2. We are currently using a 2-tank system which supplies both the liquid and gaseous nitrogen to our facility.
We are averaging 80 to 90 SCFM of utility nitrogen and 6 -7 SCFM of High Purity Nitrogen. We would continue to maintain our liquid nitrogen supply.

Please provide your positive and negative experiences with Nitrogen generators as well as the manufacturer of the unit. All comments/suggestions are welcomed.  Thanks in advance for your input.

Hi All!

We (NYU) are working on renovating our cleanroom and had a question:

How much does it cost to replace the HEPA filters in the lab (and how big
is the cleanroom you are replacing them in)?

Thank you!

I have used OnSite N2 generators and they have performed well and reliably.
I agree with Joe's comments below. If you need >99.9995% you can add a
purifier.

Hello Richard,

 

At MNMS Cleanroom in MechSE at UIUC, we used www.onsitegas.com to purchase a
99.9995% n2 Gen. They were cheaper for a better purity and flow rate than
Parker. It's overkill for most of our N2 needs, but it's cheaper to supply
99.9995% to everything than to have both low and high purity N2 lines
running around the facility. OnSiteGas sales team was great. We did have one
issue during install. We used a SS flex hose to supply compressed air to the
N2 Gen. This caused the system to "ring" every time it generated N2. I
recommend using the really simple rubber hose onsitegas provides to connect
from CDA to N2Gen to minimize vibration and resulting noise. 

 

The maintenance is super simple. Just a few compressed air filters on a
regular schedule. Approx $500 a year. As long as the N2Gen has compressed
air, it pumps out nitrogen. 

 

This was our sales rep. I'm not sure if he's still there.

Hi Howard, 

 

I ran into a similar problem with our Samco 10NR a few years back, the leak
came from large flakes on the TGV O-ring seal. Your Kalrez-ring maybe fine
to reuse. See attached Vatvalve Schematic.   

 

Give me a call at Cell 978-930-3264, I can walk you through it over the
phone.

 

 

Thanks,

Kalvin Huoth

Our SAMCO 10NR RIE has a vacuum leak.  Changed all the easy O-rings. Anyone
have an exploded diagram of the Turbo Gate Valve (TGV) or instructions for
the replacement of the TGV O-rings.

 

Thanks

I'm looking for a recommended small footprint LPCVD system.? My 
cleanroom "chase" is above the room so the entire furnace system needs 
to be inside the clean area.? I'm looking for maximum 4" size wafers.

Hello everyone;
In our cleanroom we have an old SSEC mask processor, model M3300ML. The tool has been off for a long time and now we are trying to bring the tool to life again, but we are facing some problems and we are stuck.
If someone knows any engineer that can provide help or maintenance service for this equipment, please contact me. I couldn't find anyone and the company doesn't exist anymore.
