Patent number: 8828887Abstract: In sophisticated semiconductor devices, an efficient stress decoupling may be accomplished between neighboring transistor elements of a densely packed device region by providing a gap or a stress decoupling region between the corresponding transistors. For example, a gap may be formed in the stress-inducing material so as to reduce the mutual interaction of the stress-inducing material on the closely spaced transistor elements. In some illustrative aspects, the stress-inducing material may be provided as an island for each individual transistor element.Type: GrantFiled: November 28, 2012Date of Patent: September 9, 2014Assignee: GLOBALFOUNDRIE Inc.Inventors: Kai Frohberg, Frank Feustel, Thomas Werner
