Question

ingot than at the seed-end? 6. The equation that gives the impurity concentration along the length of a CZ ingot Cs is given as: Cs = koCo (1-X)ko-1 where ko is the segregation-coefficient (see Table 9. 1), X is the melt-fraction that has solidified, and Co is the initial impurity-concentration in the melt. Using this equation, plot the doping distribution of (a) arse- nic; and (b) phosphorus, at distances of 20, 40, 60, 80, and 90 cm from the seed-end of a 100-em long ingot that has been pulled from a melt with an initial doping concentration of 1016 cm 7. Describe the differences between exrinsic and et
