摘要: A fin field-effect transistor (finFET) with improved source/drain regions is provided. In an embodiment, the source/drain regions of the fin are removed while spacers adjacent to the fin remain. An angled implant is used to implant the source/drain regions near a gate electrode, thereby allowing for a more uniform lightly doped drain. The fin may be re-formed by either epitaxial growth or a metallization process. In another embodiment, the spacers adjacent the fin in the source/drain regions are removed and the fin is silicided along the sides and the top of the fin. In yet another embodiment, the fin and the spacers are removed in the source/drain regions. The fins are then re-formed via an epitaxial growth process or a metallization process. Combinations of these embodiments may also be used.

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.

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.
