Evaporation and sputter deposition [15] 1. a)In the plasma of a sputter deposition system, consider an argon atom that is ionized during a collision in the plasma. i) Express the ratio of the acceleration of the liberated electron to that of the argon ion in terms of M and m, the mass of the ion and electron; give the numerical value of this ratio, and say in which

This lab session will utilize photolithography and dry etching to transfer a pattern from a mask to a substrate. In Step 1. 1, the thickness and the refractive index of the silicon nitride film are measured. In Step
