You just got a job at Shin-Etsu Chemical growing Si crystals with different dopants. Howmuch Ga needs to be added to 800 kg of Si melt to achieve a 5-10 Ω.cm (measured at midheight) Si CZ crystal with the following characteristics: height: 7 ft, width: 12 inchesdiameter. Assume, angular rotation 10 RPM, melt viscosity 0.1 poise, pull velocity 2mm/min.a. Generate a plot of the doping distribution throughout the length of the crystal (CGa vs. fs ).b. If a second crystal were to be pulled out of the melt without replenishment of silicon nordopant what would be the average resistivity of this crystal (or resistivity at mid height)
