Abstract: In a replacement gate scheme, a continuous material layer is deposited on a bottom surface and a sidewall surface in a gate cavity. A vertical portion of the continuous material layer is removed to form a gate component of which a vertical portion does not extend to a top of the gate cavity. The gate component can be employed as a gate dielectric or a work function metal portion to form a gate structure that enhances performance of a replacement gate field effect transistor.

Abstract: A finFET and method of fabrication are disclosed. A sacrificial layer is formed on a bulk semiconductor substrate. A top semiconductor layer (such as silicon) is disposed on the sacrificial layer. The bulk semiconductor substrate is recessed in the area adjacent to the transistor gate and a stressor layer is formed in the recessed area. The sacrificial layer is selectively removed and replaced with an insulator, such as a flowable oxide. The insulator provides isolation between the transistor channel and the bulk substrate without the use of dopants.

Abstract: A method for forming a semiconductor device includes forming gate stacks on a crystalline semiconductor layer; depositing a spacer layer over a top and sidewalls of the gate stacks; recessing the semiconductor layer between the gates stacks; and depositing a non-conformal layer over the gates stacks and within the recesses such that the non-conformal layer forms a pinch point over the recesses. The non-conformal layer is etched at a bottom of the recesses through the pinch point to expose the semiconductor layer. Dopant species are implanted at the bottom of the recesses through the pinch point in the semiconductor layer. The non-conformal layer is stripped, and source and drain material is grown in the recesses. The dopant species are activated to form PN junctions to act as a junction butt between portions of the semiconductor layer.

Abstract: CMOS devices (60, 61, 61?) having improved latch-up robustness are provided by including with one or both WELL regions (22, 29) underlying the source-drains (24, 25; 31, 32) and the body contacts (27, 34), one or more further regions (62, 62?, 62-2) doped with deep acceptors or deep donors (or both) of the same conductivity type as the corresponding WELL region and whose ionization substantially increases as operating temperature increases. The increase in conductivity exhibited by these further regions as a result of the increasing ionization of the deep acceptors or donors off-sets, in whole or part, the temperature driven increase in gain of the parasitic NPN and/or PNP bipolar transistors inherent in prior art CMOS structures. By clamping or lowering the gain of the parasitic bipolar transistors, the CMOS devices (60, 61, 61?) are less likely to go into latch-up with increasing operating temperature.

Abstract: A field effect transistor (FET) structure on a semiconductor substrate which includes a gate structure having a spacer on a semiconductor substrate; an extension implant underneath the gate structure; a recessed source and a recessed drain filled with a doped epitaxial material; halo implanted regions adjacent a bottom of the recessed source and drain and being underneath the gate stack. In an exemplary embodiment, there is implanted junction butting underneath the bottom of each of the recessed source and drain, the junction butting being separate and distinct from the halo implanted regions. In another exemplary embodiment, the doped epitaxial material is graded from a lower dopant concentration at a side of the recessed source and drain to a higher dopant concentration at a center of the recessed source and drain. In a further exemplary embodiment, the semiconductor substrate is a semiconductor on insulator substrate.
