Abstract: A semiconductor device includes transistor cells and enhancement cells. Each transistor cell includes a body zone that forms a first pn junction with a drift structure. The transistor cells may form, in the body zones, inversion channels when a first control signal exceeds a first threshold. The inversion channels form part of a connection between the drift structure and a first load electrode. A delay unit generates a second control signal which trailing edge is delayed with respect to a trailing edge of the first control signal. The enhancement cells form inversion layers in the drift structure when the second control signal falls below a second threshold lower than the first threshold. The inversion layers are effective as minority charge carrier emitters.

Abstract: A method for manufacturing a thin film resistor (TFR) module includes forming a TFR element over a substrate; annealing the TFR element to reduce the temperature coefficient of resistance (TCR) of the TFR element; and after forming and annealing the TFR element, forming a pair of conductive TFR heads in contact with the TFR element. By forming the TFR element before the TFR heads, the TFR element may be annealed without affecting the TFR heads, and thus may be formed from various materials with different annealing properties, e.g., SiCCr and SiCr. Thus, the TFR element may be annealed to achieve a near 0 ppm TCR, without affecting the later-formed TFR heads. The TFR module may be formed using a damascene CMP approach and using only a single added mask layer. Further, vertically-extending “ridges” at edges of the TFR element may be removed or eliminated to further improve the TCR performance.
