You have developed an idea for using a poly Si surface‐ micromachined cantilever. Initially, you designed a process flow for creating this simple structure, and the process flow is detailed in the figure below. ( cross section view and top view)There are several critical errors with this process (things that won’t work or won’t produce the result). Please find the critical errors in this process flow and, where possible, suggest alternate approaches. Do not worry about the accumulation of errors, but rather treat each step assuming that the structure up to that step could be created.This structure is actually quite simple to make. Develop a simpler process flow and associated masks to create the final structure. Be sure to show cross‐sectional and planar views of all key steps in the process.

12. You plot the current-voltage characteristics of a new non-ohmic device, perform a curve fit, and discover the current as a function of voltage is given by the equation: I = (9Amp/volt")V² – (7Amp/volt) V (a). Perform calculations to find the slope of a line tangent to this curve when V = 4.15 volts. (b). Calculate the effective resistance of this device when V = 4.15 volts. This device is Non-Ohmic!
