摘要:
In one embodiment, the disclosure relates to a method for forming a semiconductor power device by depositing a first layer of TiW on a gate region and a source region, depositing a second layer of refractory metal over the first layer of TiW at the gate region, depositing a dielectric stack over the second layer of refractory metal and a portion of the first layer of TiW, depositing an etch stop layer over a portion of the dielectric stack, depositing an interconnect layer over the etch stop layer and the dielectric stack and depositing an etch mask over the interconnect layer.
