    摘要: A semiconductor device having multiple fin heights is provided. Multiple fin heights are provided by using multiple masks to recess a dielectric layer within a trench formed in a substrate. In another embodiment, an implant mold or e-beam lithography are utilized to form a pattern of trenches in a photoresist material. Subsequent etching steps form corresponding trenches in the underlying substrate. In yet another embodiment, multiple masking layers are used to etch trenches of different heights separately. A dielectric region may be formed along the bottom of the trenches to isolate the fins by performing an ion implant and a subsequent anneal.

    摘要: A system and method for forming a semiconductor device with a reduced source/drain extension parasitic resistance is provided. An embodiment comprises implanting two metals (such as ytterbium and nickel for an NMOS transistor or platinum and nickel for a PMOS transistor) into the source/drain extensions after silicide contacts have been formed. An anneal is then performed to create a second silicide region within the source/drain extension. Optionally, a second anneal could be performed on the second silicide region to force a further reaction. This process could be performed to multiple semiconductor devices on the same substrate.
