A boron diffusion into a 1 -ohm-cm n type wafer results in a Gaussian profile with a surface concentration of 5 x 10^18/cm^3 and a junction depth of 4um.
a)how long did the diffusion take if the diffusion temperature was 1100 degrees C?
b)what was the sheet resistance of the layer?
c)what is the dose in the layer?
