    Abstract: A method for fabricating a semiconductor device includes forming an SiGe region. The SiGe region can be an embedded source and drain region, or a compressive SiGe channel layer, or other SiGe regions within a semiconductor device. The SiGe region is exposed to an SC1 solution and excess surface portions of the SiGe region are selectively removed. The SC1 etching process can be part of a rework method in which overgrowth regions of SiGe are selectively removed by exposing the SiGe to and SC1 solution maintained at an elevated temperature. The etching process is carried out for a period of time sufficient to remove excess surface portions of SiGe. The SC1 etching process can be carried out at elevated temperatures ranging from about 25° C. to about 65° C.

    Abstract: In a method of making a semiconductor device, a first gate stack is formed on a substrate at a pFET region, which includes a first gate electrode material. The source/drain regions of the substrate are etched at the pFET region and the first gate electrode material of the first gate stack is etched at the pFET region. The etching is at least partially selective against etching oxide and/or nitride materials so that the nFET region is shielded by a nitride layer (and/or a first oxide layer) and so that the spacer structure of the pFET region at least partially remains. Source/drain recesses are formed and at least part of the first gate electrode material is removed by the etching to form a gate electrode recess at the pFET region. A SiGe material is epitaxially grown in the source/drain recesses and in the gate electrode recess at the pFET region. The SMT effect is achieved from the same nitride nFETs mask.

    Abstract: Method for fabricating semiconductor devices with high-K materials without the presence of undesired formations of the high-K material. A preferred embodiment comprises forming a layer of material over a layer of a high-K material, etching the layer of material to expose a portion of the high-K material, performing a CDE (Chemical Downstream Etch) to remove any residual material formed during the etching, and etching the layer of the high-K material into alignment with remaining portions of the layer of material. The removal of the residual material results in a predictable trimming of the high-K material so that the semiconductor device has predictable and consistent performance, which is not possible if the high-K material has unpredictable dimensions.
