摘要： System and method for reducing contact resistance and prevent variations due to misalignment of contacts is disclosed. A preferred embodiment comprises a non-planar transistor with source/drain regions located within a fin. An inter-layer dielectric overlies the non-planar transistor, and contacts are formed to the source/drain region through the inter-layer dielectric. The contacts preferably come into contact with multiple surfaces of the fin so as to increase the contact area between the contacts and the fin.

摘要： A method of forming a semiconductor structure includes providing a composite substrate, which includes a bulk silicon substrate and a silicon germanium (SiGe) layer over and adjoining the bulk silicon substrate. A first condensation is performed to the SiGe layer to form a condensed SiGe layer, so that the condensed SiGe layer has a substantially uniform germanium concentration. The condensed SiGe layer and a top portion of the bulk silicon substrate are etched to form a composite fin including a silicon fin and a condensed SiGe fin over the silicon fin. The method further includes oxidizing a portion of the silicon fin; and performing a second condensation to the condensed SiGe fin.

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.
