Stoichiometric Silicon Nitride LPCVD Wafers

What Silicon Nitride Wafer Should I Use to Fabricate Waveguide?

Question

Our lab is planning to fabricate some silicon nitride waveguide. so we need to buy some silicon nitride wafers, which means we need around 150 nm stoichiometric silicon nitride films on thermal oxides silicon wafers. the thermal oxide layer should be at least 1 um  thickness. silicon substrate is flexible. #1385 is good thermal oxide wafer for us.  Do you have the processing service to grow 150 nm LPCVD low stress silicon nitride on #1385? can you please send me a quote? Thanks.

Answer

100mm P/B <100> 1-10 ohm-cm 500um SSP Prime Grade with 1um of Oxide and 150 nm LPCVD low stress silicon
