Question: The cross section below illustrates a simple bipolar transistor fabricated as part of a silicon Ie. (See also Figure) Design a plausible process flow to fabricate such a structure, following the ideas of the CMOS process flow in this chapter. You do not have to include any quantitative process parameters (times, temperatures. doses, etc.) Your answer should be given in terms of a series of sketches of the structure after each major process step, like the figures in this chapter. Briefly exploring your reasomug for each step and the order you choose to do things.
