Abstract:
1. A method of generating a semiconductor device on a single semiconductor substrate, comprising: providing a substrate having a silicon material portion; forming a first set of source/drain contacts from a first metal on a substrate surface that includes the Silicon material portion; annealing the first metal with the Silicon material portion at a first temperature to form the first set of source/drain contacts; subsequent to forming the first set of source/drain contacts, disposing a germanium material portion on the substrate surface on which the first set of source/drain contacts are formed proximate the silicon material portion; forming a second set of source/drain contacts from a second metal on the Germanium material portion; and annealing the second metal with the Germanium material portion at a second temperature to form the second set of source/drain contacts, wherein the second temperature is less than the first temperature.
