This lab session will utilize photolithography and dry etching to transfer a pattern from a mask to a substrate. In Step 1. 1, the thickness and the refractive index of the silicon nitride film are measured. In Step
How small would you like to go?...and can you go? with semiconductors?. with lithography 6.12J/3.155J Microelectronic processing Semiconductor scaling drivers: Speed of light in global interconnects, vac/vK Increased information density

Why spend a whole lecture on oxidation of Si? Ge has high ue, Wh, Ge stable but no oxide GaAs has high ue and direct band Why sio? Sio, is stable down to 10 9 Torr. T>900C Sio can be etched with hf which leaves si unaffected
