Draw the band diagram of a Schottky metal/semiconductor(III-V) diode. How does RIE, ICP-RIE work? what's DC bias in RIE, how do you come up with new gas chemistries to etch an unknown material. how do you control the etch profile, what's an endpoint detector, how do they work? explain the PECVD process, and it's control nobs, STD DEV and Cp, Cpk questions, ect
