Hello Madan, You can call CVD Systems & Services and speak to Bob Campbell at 610-792-1690. He would like for you to fax over your request; number of wafers, wafer size, thickness, so he can quote you. He says they do this sort of work all the time along with other micro machining and deposition work. His fax number is 610-792-1691 If you need help with dicing blades to cut the wafers into individual die please give me a call. We sell dicing blades for cutting silicon, GaAs, glass, pyrex and other materials. We understand budgets are not alway very big we offer a 10% discount to all Universities.
