b$.$

a$.$ This above structure is meant to be a MEMS device where we apply a voltage to the poly$-$sticon and

cooper and the structure deflects

What additional step should ideall be done at the end of the process assuming we want an efficient, rapidly responding device? Why? Extra points for mathematical detail $($hint: a circuit.

Hint: it is one of the core processes ie leamed in class, and is related to poly$-$silicon properties.

b$.$Draw the shape of the device and induced charges when a positive voltage is applied on copper
