    摘要: A method is provided in which an n-type field effect transistor (NFET) and a p-type field effect transistor (PFET) each have a channel region disposed in a first single-crystal semiconductor region having a first composition. A stress is applied at a first magnitude to a channel region of the PFET but not at that magnitude to the channel region of the NFET. The stress is applied by a single-crystal semiconductor layer having a second composition such that the single-crystal semiconductor layer is lattice-mismatched to the first region. The semiconductor layer is formed over the source and drain regions and optionally over the extension regions of the PFET at a first distance from the channel region of the PFET and is formed over the source and drain regions of the NFET at a second, greater distance from the channel region of the NFET, or the semiconductor layer having the second composition is not formed at all in the NFET.

    摘要: A FinFET SRAM transistor device includes transistors formed on fins with each transistor including a semiconductor channel region within a fin plus a source region and a drain region extending within the fin from opposite sides of the channel region with fin sidewalls having a gate dielectric formed thereon. Bilateral transistor gates extend from the gate dielectric. An asymmetrically doped FinFET transistor has source/drain regions doped with a first dopant type, but the asymmetrically doped FinFET transistor include at least one of the bilateral transistor gate electrode regions on one side of at least one of the fins counterdoped with respect to the first dopant type. The finFET transistors are connected in a six transistor SRAM circuit including two PFET pull-up transistors, two NFET pull down transistors and two NFET passgate transistors.
