Patent number: 8901619Abstract: Asymmetric FET devices, and a method for fabricating such asymmetric devices on a fin structure is disclosed. The fabrication method includes disposing over the fin a high-k dielectric layer followed by a threshold-modifying layer, performing an ion bombardment at a tilted angle which removes the threshold-modifying layer over one of the fin's side-surfaces. The completed FET devices will be asymmetric due to the threshold-modifying layer being present only in one of two devices on the side of the fin. In an alternate embodiment further asymmetries are introduced, again using tilted ion implantation, resulting in differing gate-conductor materials for the two FinFET devices on each side of the fin.Type: GrantFiled: May 14, 2012Date of Patent: December 2, 2014Assignee: International Business Machines CorporationInventors: Kangguo Cheng, Bruce B.
