A polysilicon layer (22,23) may need to have electrical characteristics which are relatively uniform from wafer to wafer (52,53,54,55,56). The use of polysilicon (22,23) as a resistor is one such example. In order to obtain the requisite uniformity, the temperature of the wafers (52,53,54,55,56) which are receiving the polysilicon (22,23) must all be the same within a tight tolerance. The reaction...
