We have a large selection of wafers for SU-8 photoresist for photolithography. Below is just some silicon wafer's specs purchased researchers.
"Our research clients focuses on cellular and molecular properties of axonal outgrowth and transport that are disrupted in neurodegenerative diseases."
"The wafers are used as substrates for SU-8 masks for microfluidics and microcontact stamping tools for bioengineering."
"We build microfluidic devices using PDMS, which we fabricate using a soft lithography technique on silicon wafer molds patterned with positive or negative resists. Our features are 25-50 microns tall and 10-150 microns wide. We've found very good adhesion of both SU-8 2025 and AZ-40XT-11d resists on your wafers."
" I am using the wafers to create microfluidic device molds by SU-8 photolithography."
The above item #452 is also used by researchers to "create biological molds using SU-8 photoresist. These molds in turns are then cast into a plastic called PDMS and used to study cell behavior and its interactions for the purpose of create a cancer diagnostic.
"Would (452) those wafers work for spin coating SU-8 photoresist on them? These wafers will be used for fabricate microfluidic chips."
PDMS is polydimethulsiloxane. I need to coat SU-8 on the wafers first, then put PDMS on it. I just need a smooth surface so that I can peel the PDMS off later.
Researchers use the following wafers for mold making.
"I would like to order 100mm silicon wafer for SU8 lithography on one side, so I believe it has to be polished on one side. Could I ask you which silicon wafer you will choose for that? You have many different types and Im not sure which one is the best for me."
"My student is using the wafers for microfluidic masters (aka molds). He is spinning SU-8 photoresist onto the wafers and patterning the photoresist to make these masters."
In some cases researchers perfer a rough surface to a smooth surface. Mechanical grade wafers are often used.
" There is nothing wrong with the wafers, but it is not suitable for our application. We are working with the photoresist, such as SU-8 and AZ-9620. The 1196 is working well, but the surface of 452 is too smooth for the photoresist to stick, even after being treated with HMDS."
The intended use is for photolithography purposes using SU-8 negative photoresist for your reference.
Corning Eagle Glass
Researcher: "We're using them in photolithography and going to put down SU8, do you have a suggestion? I've used Corning Eagle glass before, but you don't have any 6"
"I would like to buy SU8 and also silicon wafer for our lab. We need to fabricate a mold for PDMS fabrication. We need high thickness (around 500 micron). Firstly, I would like to consult with you about which type of SU8 products is suitable for our work? and also I need the most economical price for them. Thanks."
"Hi, We would like to purchase wafers for using microfluidic applications (with SU-8 photoresist and PDMS). I think silicon test wafer is appropriate for us, I think ID is 857. Could you please send a proforma for 10 wafers? "
