A CMOS metal layer with resistivity, p = 1.6x10⁻⁸ Ωm is 0.1 µm thick. It is used to draw a signal trace that is 100µm long and 0.1 µm wide.
a) Calculate the sheet resistance, Rs, of this metal layer.
b) How many "squares", n, are in the signal trace?
c) Use the results in (a) and (b) to determine the resistance of the trace.
