. Based on CZ method, the engineer wants to produce Si Ingot with 10 cm of diameter and 1 meter of height. (10 points) (a) At least how much weight of Si is required in the crucible to melt? (5 points) (b) In the middle of ingot, how much of initial concentration is required to have phosphorus- doped silicon wafer with concentration of 10¹/cm³? (15 points) Use below equation ao of silicon= 5.43Å Å = 10-¹⁰m Si molar weight = 28.1g/mol phosphorus molar weight = 31g/mol ko,phosphorus 0.35 Cs=k,C.(1-M/Mo)ko-1) .
