What Are Undoped Silicon Wafers Used For?

We can custom make wafers in small quantities. We can dice them, thin them to 2um. We have undoped, low doped and highly doped Silicon substrates that are always in stock.

Typical Client Question regarding Undoped Silicon Wafers:


After looking at your online store, I think we might go with your cheapest silicon wafers, product ID 444. I am in a group that is working on a Senior Design Project to create a biobattery. We need a substrate to pattern with photolithography and subsequently deposit various precious metals on that will catalyze certain reactions and conduct electricity. If you have any advice on specific types of wafers we will need for such nano electronic devices I would be happy to know. Thanks.

We make nanomaterials in our lab and one approach is using electrical explosion of wires (EEW). We used one of Scott's old Si wafers (doped with B) and broke off a strip of Si that we attached to electrodes in our EEW apparatus. It worked nicely and we are looking to do the same thing with Ge (Germanium Wafer). We need a wafer that is less than 500 microns thick. Fill out the form and receive an immediate quote.
