Question

Silicon for computer chips is grown in large cylinders called "boules" that are 300 mm in diameter and 2 m in height. The density of silicon is 2.33 g/cm^3. Silicon wafers for making integrated circuits are sliced from a 2.0 m boule and are typically 0.75 mm thick and 300 mm in diameter. How many wafers can be cut from a single boule?

Answer 1

number of wafers = volume of 2m boule / volume of an individual wafer
