摘要： The present invention relates to a semiconductor-on-insulator (SOI) substrate having one or more device regions. Each device region comprises at least a base semiconductor substrate layer and a semiconductor device layer with a buried insulator layer located therebetween, while the semiconductor device layer is supported by one or more vertical insulating pillars. The vertical insulating pillars each preferably has a ledge extending between the base semiconductor substrate layer and the semiconductor device layer. The SOI substrates of the present invention can be readily formed from a precursor substrate structure with a “floating” semiconductor device layer that is spaced apart from the base semiconductor substrate layer by an air gap and is supported by one or more vertical insulating pillars. The air gap is preferably formed by selective removal of a sacrificial layer located between the base semiconductor substrate layer and the semiconductor device layer.

摘要： Disclosed are embodiments of an n-FET structure with silicon carbon S/D regions completely contained inside amorphization regions and with a carbon-free gate electrode. Containing carbon within the amorphization regions, ensures that all of the carbon is substitutional following re-crystallization to maximize the tensile stress imparted on channel region. The gate stack is capped during carbon implantation so the risk of carbon entering the gate stack and degrading the conductivity of the gate polysilicon and/or damaging the gate oxide is essentially eliminated. Thus, the carbon implant regions can be formed deeper. Deeper S/D carbon implants which are completely amorphized and then re-crystallized provide greater tensile stress on the n-FET channel region to further optimize electron mobility. Additionally, the gate electrode is uncapped during the n-type dopant process, so the n-type dopant dose in the gate electrode can be at least great as the dose in the S/D regions.

摘要： A semiconductor structure for use as a template for forming high-performance metal oxide semiconductor field effect transistor (MOSFET) devices is provided. More specifically, the present invention provides a structure that includes a SiGe-on-insulator substrate including a tensile-strained SiGe alloy layer located atop an insulating layer; and a strained Si layer atop the tensile-strained SiGe alloy layer. The present invention also provides a method of forming the tensile-strained SGOI substrate as well as the heterostructure described above. The method of the present invention decouples the preference for high strain in the strained Si layer and the Ge content in the underlying layer by providing a tensile-strained SiGe alloy layer directly atop on an insulating layer.

摘要： The embodiments of the invention provide a method, etc. for a pre-epitaxial disposable spacer integration scheme with very low temperature selective epitaxy for enhanced device performance. More specifically, one method begins by forming a first gate and a second gate on a substrate. Next, an oxide layer is formed on the first and second gates; and, a nitride layer is formed on the oxide layer. Portions of the nitride layer proximate the first gate, portions of the oxide layer proximate the first gate, and portions of the substrate proximate the first gate are removed so as to form source and drain recesses proximate the first gate. Following this, the method removes remaining portions of the nitride layer, including exposing remaining portions of the oxide layer. The removal of the remaining portions of the nitride layer only exposes the remaining portions of the oxide layer and the source and drain recesses.

摘要： An embedded silicon carbon (Si:C) having a substitutional carbon content in excess of one percent in order to effectively increase electron mobility by application of tension to a channel region of an NFET is achieved by overfilling a gap or trench formed by transistor gate structures with Si:C and polishing an etching the Si:C to or below a surface of a raised gate structure in a super-Damascene process, leaving Si:C only in selected regions above the transistor source and drain, even though processes capable of depositing Si:C with sufficiently high substitutional carbon content are inherently non-selective.
