4.) Compare the concentration profile of arsenic impurities in a 1.2 meter long Si ingot grown by (a.) the CZ technique and (b.) the FZ technique. Show this comparison in the form of a plot. Assume the starting concentration of the feed in both cases be 21018cm3. Also assume the zone length for the FZ growth is 6cm. (a.) Plot concentration on a log scale. Assume e=. Label your plots. 5.) What is the effective partition coefficient, e, of carbon (=0.07) in Si given the following pull conditions: pull rate of 1.5mm/min, rotation rate of 3rpm,v= 3.5103cm2/s, and D=2105cm2/s
