Q2.
Transistors are manufactured by doping semiconductors. The diffusion coefficient of phosphorus in Si is D = 6.5 x 10-11 mm2/s at a temperature of 950°C. Assume the source provides a surface concentration of
1020 atoms/cm3 and the diffusion time is one hour. Assume that the silicon wafer initially contains no phosphorus. Calculate the depth at which the concentration of phosphorus will be 1018 atoms/cm3.
The active area of the amd ryzen 5950x processor in high end computers today has about 19.2 billion transistors (transistors are semiconductor device that control electronic processes). The dimensions of the die sizes are 2x 80.7 + 125 (I/O) mm2 (please refer to the image below.). What are the dimensions of one transistor on the die, assuming that all of the area across the die is transistors and each is a square?
