From schweig at umich.edu Wed Feb 1 08:02:09 2017 From: schweig at umich.edu (Dennis Schweiger) Date: Wed, 1 Feb 2017 08:02:09 -0500 Subject: [labnetwork] LED cleanroom lights Message-ID: Norman, good morning. We're going through this exact process right now here at UofMichigan in the older portion of our cleanroom, as part of the project when we replace the HEPA filters. It's been a long learning curve to get to the final answer. We've also reevaluated our "yellow" light capability and found that what we were using wasn't as effective as we thought, and we needed to be more "orange" to filter out the blue spectrum. When we decided to change the color, it was obvious that we needed more lamps to get the lumen output back up where it wasn't like working in a closet. We found a local (Michigan area) lighting manufacturer that is remaking the tombstone support brackets to increase our lamp count from 2 bulbs to 4 bulbs, in various strategic fixtures throughout the lab, and we're installing an improved tombstone with the retrofit. They had their UL guy take a look at what we wanted to do, and we've been told that our old fixtures, with the extra bulbs, will still meet the UL listing requirement that our inspectors are requiring, provided we install the LED bulbs as per specification. We've been looking at changing over all of our mechanical spaces to LED as well, and we've found that some of the fixtures have the lamp pins oriented vertically, and not horizontally. For fluorescent tubes, this isn't a big deal because they generate light 360 degrees. For the LED lamps, there's a blank spot on the "top" of the tube where no light is generated. We're currently testing the functionality of using the LED lamp in a "90 degree out of rotation" installation. So far, it seems to work just fine, both in operation, and in light generation. I've attached the cut sheets on the T-8 replacement LED lamps (direct wire 277 LED that fit a T-12 and T-8 socket) we're using, along with the T-5 LED equivalent we're looking at (these still require a ballast). I've also included the information I've compiled on the "yellow/orange" filters that we're still evaluating. I've found that not all of the tube filters that fit a T-8, or T-5, fluorescent tube, will fit over their respective LED replacement. For the filters, be prepared to see a huge variation in pricing, both in quantity, and from manufacturer. If you'd like to come out and take a look at what we've done (the cleanroom won't be fully retrofitted with new filters and lamps till late April), just give me a call. By the way, just to give you some idea of the scope we're talking about, in just the cleanroom there are 197 lighting fixtures, and the mechanical spaces add about another 150 fixtures.

HAMILTON) Date: Wed, 1 Feb 2017 08:57:25 -0800 Subject: [labnetwork] LED cleanroom lights In-Reply-To: References: Message-ID: Norman Bergen, I can share some information about LED lights with the same form-factor as T-series fluorescent lamps. I think it's a great idea trying LED's in a cleanroom. The interruption and act of re-lamping far outweighs the cost of conversion. Beside lamp failures there are ballast failures which cause odors and can smoke. The heat load for a cleanroom will also be reduced. I note there are even yellow LED's in a T-series form-factor; however, I have no experience with their light profile and its affect on photoresists, Also, most fluorescent light troughs in buildings are powered 277 Volts so one must select the appropriate LED replacement lamp - they do come in 277 V: https://www.americool.com/277Volt.htm My experience replacing older F15T lamps is via my hobby and not from our cleanroom. I hybridize plants and have a growth room for vitro growth. Nothing sordid; Andean orchids, note dope!. The heat load of my upstairs room during the summer is sometimes excessive so I decided to re-lamp the shelves with LED's which has proved effective. The cost of LED's ended only slightly more than buying replacements T15's at Home Depot because I ordered them as a case of ten. The wiring in the existing fixtures needed slight modification. The existing "tombstone" (bi-pin sockets) were of the shunted variety. Tombstones come both shunted and un-shunted. A classical Hg-type lamp requires shunted bi-pins because the lamp is powered from each end. The LED replacements requires power across the bi-pins at either end. Replacing the tombstones was a piece of cake. Out out laziness, the ballasts were left in the fixtures; however, they were disconnected. Bypassing them was quite simple. So far, so good. I am pleased with the light output and reduced heat load. I've had no failures in a year. I run lamps rated at 5500K CRI given a plants need for blue light. LED replacements are available at 4000K and 3000K, color temperatures that are less harsh. I have recently seen some lamps advertised as direct replacements without the need of any re-wiring; however, I have no experience with these.

I did use a 1/4" polycarbonate sheet. The manufacturer made a custom color to meet my transmission criteria. I wanted transmission <0.01 (my definition of "cutoff") at 450nm I wanted the material to look yellow (cutoff between 450 and 480nm) "yellow" products do not meet this spec. (cutoff ~430nm) "amber" products meet this spec but I considered them too dark. (cutoff is ~550nm) I requested a custom "double yellow" product. (i.e. put 2x the amount of yellow dye in the same thickness product) What I received was a 3x product - and I liked it. And it met transmission criteria cutoff was ~470nm I proposed that the manufacturer call this custom color "Golden Bear Yellow 1868" They had a minimum order requirement to make a custom color but then cost was equivalent to off the shelf colors.

Wafers were coated with resist and left exposed to the yellow light for 5 days and then developed for 1 min. The change in resist thickness was in the 3-6 % range. By contrast, the resist was completely developed for wafers exposed to the light from fixtures with TAPR50 film. Another yellow film was purchased through a local cleanroom equipment supplier but we do not have information on the manufacturer. From what I remember it performed worse than the TAPR50 film.

One of our consultants, David Alessi, from Stantec chose this product after exploring a number of options. It does come in a film that can be installed on pre-existing windows (this was done on a few windows that were missed during the lab construction). Thus far we have been happy with it. It is more ?amber? and bit darker than the ?yellow? filters we use in our older facility; although, that being said, it still allows enough higher wavelength light to pass for good visibility (transmission spikes just around 520nm). It blocks >99% of UV below 380nm and it blocks >90% of light in the 400-500nm range (note that while transmission is still below 10% at g-line, it does allow slightly higher transmission in this area of the spectrum as compared to the higher end of the 400-500nm range). One additional item to note is that some of these window films can be soft and are relatively easy to cut or scratch, even after they are installed. We are happy the Amber 81 product, but we have had a couple of occasions where scratches occurred as a result of someone leaning or bumping something against the window.

After lots of testing we settled on a photographic darkroom film that had a cutoff wavelength of 500 nm. 610 nm and 625 nm are available as well. The chart and link below my signature provide more detailed information. The chart below shows various darkroom films. We opted for the Yellow Gold 500. The film comes in rolls and is non-adhesive. We hired a local window tinting company to strip off any architectural films and attach the YG10 with about 4 mm wide double stick tape. They did a great job, no wrinkles. At first I thought a non-adhesive film was a disadvantage but I changed my mind. A couple experts have told me that the best of films can age and eventually may start leaking UV and need replacing, so the easily removable approach sounded good. Our films are about 4 years old and are not leaking yet but we stay vigilant. . Best, Vince Vincent K.

We have windows within our facility that should have been covered, but weren't, and have some currently installed films that don't filter out as much UV as we'd like.

I am retiring from Purdue on Friday, February 17, 2017 - this Friday. I have had a very profitable and enjoyable career over the past 45 years, and am now ready to "hang it up." I will still be somewhat active in nanotechnology - I'm retaining my role as Vice President of Strategic Planning for IEST, I'm continuing to work on my Nanotechnology Facility Design book, and may do some consulting - and would therefore like to remain on the labnetwork list if that is okay. I began my career in the semiconductor industry on RCA 4000 series integrated circuits. We were putting 8 transistors on a chip! I'm now involved in nanotechnology where we are putting billions - with a "b" - of transistors on a chip. It makes my head spin just thinking about it! I had the chance to work with many pioneers of the semiconductor industry, beginning my career in the first CMOS factory in the world. I certainly have enough memories to bore my grandchildren! My sixth grandchild, Joshua James Smith, was born last week and retirement will allow me to spend more time with them. I will also be concentrating on my military history avocation - I have a book that is 70 % complete, a TV documentary that is underway, and am helping with a lot of 200th anniversary celebrations that will begin in 2018. I'm also still active in historical research working with National Park Service for in-service training for park rangers and volunteers. Finally, I have an active wood shop and an infinite list of furniture that my wife wants me to build - infinite because each time I complete a project she adds two more :). I have greatly enjoyed working with all of you over the years and hope to keep in touch. I thank all of you for so freely sharing your knowledge with me and for challenging me to consider new things and continue learning. It has been a great run, but now it's time for me to do what I want, when I want. Life is good! My new contact information is below. John John R.

From the literature it was not easy to determine which system fulfilled our requirements best the ?PG or the MLA100. Myself and our process engineer visited Heidelberg at their HQ to see the systems. We took wafers exposed on our EBL system as we wanted to see how easily and accurately the HIMT systems aligned to our wafers. The ?PG was quite difficult as the field of view on the alignment camera was so small that it took the HIMT engineer a long time to find the mark. We also found out that to expose a full wafer or even a sparse pattern over a large area would be very time consuming. We ruled this system out quite quickly due to. Having to change write heads, Not a very easy system to align on (this was based on our user base) Slow exposures. The MLA 100 is the system we spent most of the day on. The alignment is much easier as the system has an overview camera. The exposure was much faster. The alignment was good on both etched and metal marks. While there we had a tour of the facility and they showed us the MLA150. This system is roughly 10X faster than the MLA100 with better alignment specs. We ended up buying the MLA150 with is currently being installed in our cleanroom. It's available with 2 lasers 405nm and 375nm. Backside alignment and greyscale are also options. Of course it's at a different price point. I hope this helps. If you need more feel free to contact me.
