Gettering of iron by oxygen precipitates

WebInternal gettering efficiencies and stabilities of high and low carbon doped silicon have been compared with standard and ramped annealing conditions. The gettering efficiency of low carbon silicon has been found to be greatly enhanced with ramped annealing by creating a high concentration of oxygen precipitates and related defects. This ramped low carbon … WebNov 1, 2016 · The factors on gettering effectiveness are studied, including the fabrication procedures and the structures of the polysilicon passivating contact.
