Abstract
A method for making an integrated circuit includes a) providing a substrate including n-type metal oxide semiconductor field effect transistors (NMOSFETs) and p-type metal oxide semiconductor field effect transistors (PMOSFETs), wherein channel regions of the NMOSFETs and the PMOSFETs include germanium; b) depositing and patterning a mask layer to mask the channel regions of the PMOSFETs and to not mask the channel regions of the NMOSFETs; c) passivating an exposed surface of the substrate; d) removing the mask layer; and e) depositing a metal contact layer on both the NMOSFETs and the PMOSFETs.
