Frequently Asked Questions

At what stage in the development of my device should I come to MMD?
Our typical customer has already been through at least one prototyping run and is now ready for volume production. We specialize is advanced MEMS materials and fabrication, not in MEMS device design. However, if you require design assistance, our partnerships with research universities and design companies can dramatically accelerate your cycle time from proof-of-concept to production ready to market launch. If you want to move fast and emerge with the best MEMS enabled product, contact us now. We can help you win your market share of the Internet of Things.

What wafer sizes do you work with?
Our production line is presently tooled for 100mm wafers. If your product requires 150mm wafers, we can add to our current capacity. In addition, we can and have worked with a variety of unconventional or unique substrate shapes and sizes. We can help you invest your capital into the most productive media based on our ten years of MEMS fabrication experience.

What substrates will you work with?
Midwest MicroDevices is experienced working with a wide variety of substrate materials; SOS, SOI, glass, quartz, and even flexible substrates are just a few that we have experience with. Our automated production line is capable of handling opaque, transparent, and semi-transparent substrates.

What materials will you work with?
We routinely process with materials considered contaminants by other foundries. Gold, Platinum, Silver, Bismuth, Antimony, Nickel, and Germanium are just a few of the materials that we use in regular production. Have an unusual material requirement? Contact us to see if we can help.

Do you have a minimum order quantity?
For prototype and first-time production runs, we typically process a minimum of 12 wafers. Our production line can handle recurring production in quantities from 24 wafers per year to over 500 wafers per year, depending upon the application.

Our typical application contains from 5-10 photolithography mask layers and over 100 individual processing steps. Do you have an application that is more complex?
Contact us. We cannot divulge our client’s technologies. Let’s just say that we love to be challenged!

I have been told that my device cannot be manufactured. Can you help?
Yes we can! It’s what we do: turn a challenging prototype device into a fully buildable and reliable product. Put our engineering team to work to see how we can help you.

Do you have additional questions that are not answered here?
