... using low pressure chemical vapor deposition to give a silicon nitride film with <250 MPa tensile stress. Silicon on one side of the wafer was exposed by removing the nitride layer with photolithography + reactive ion etching, which was followed by etching in ~25% KOH for 6-8 hours to etch the windo ...

... The conversion process and data acquisition are controlled using standard control inputs, allowing easy interfacing to microprocessors or DSPs. The input signal is sampled on the falling edge of CONVST, and conversion is also initiated at this point. BUSY goes high at the start of conversion and goe ...
