1. The problem statement, all variables and given/known data A doped silicon ingot is to be grown by the Czochralski technique with a dopant concentration of 1016boron atoms/cm3. If k0 = 0.9 for boron/Si, what concentration of boron atoms should be in the melt? 2. Relevant equations Cs/C0 = k0 (1 - m/m0) k0-1 k0 = Cs / Cl 3. The attempt at a solution I think it's just a case of subbing in the numbers to establish Cs and then using this in the second equation to find Cl, but I'm really confused about what the values of M and M0 should be in this scenario.
