    Abstract: Performance of a FinFET is enhanced through a structure that exerts physical stress on the channel. The stress is achieved by a combination of tungsten contacts for the source and drain, epitaxially grown raised source and raised drain, and manipulation of aspects of the tungsten contact deposition resulting in enhancement of the inherent stress of tungsten. The stress can further be enhanced by epitaxially re-growing the portion of the raised source and drain removed by etching trenches for the contacts and/or etching deeper trenches (and corresponding longer contacts) below a surface of the fin.

    Abstract: Methods, non-transitory computer readable media, and systems are provided for detecting an endpoint of a chemical mechanical planarization (CMP) process on a semiconductor substrate. The method comprises generating a reference signal, generating a first signal with which to control a CMP system, generating a second signal using a combination of the first signal and the reference signal, commanding the CMP system with the second signal, generating a response signal that indicates an operational characteristic of the CMP system that is responsive to the second signal and a friction property of the semiconductor substrate, and filtering the response signal using the reference signal to determine the endpoint of the CMP process.

    Abstract: One illustrative method disclosed herein includes, among other things, forming a plurality of fin-formation trenches that define a fin, forming a first stressed layer within the trenches and above the fin and performing at least one etching process on the first stressed layer so as to define spaced-apart portions of the first stressed layer positioned at least partially within the trenches on opposite sides of the fin. The method also includes forming spaced-apart portions of a second stressed layer above the spaced-apart portions of the first layer, forming a third stressed layer above the fin between the spaced-apart portions of the second layer and, after forming the third layer, forming a conductive layer above the second and third layers.
