    摘要: A method of semiconductor device fabrication including providing a substrate having a gate dielectric layer such as a high-k dielectric disposed thereon. A tri-layer element is formed on the gate dielectric layer. The tri-layer element includes a first capping layer, a second capping layer, and a metal gate layer interposing the first and second capping layer. One of an nFET and a pFET gate structure are formed using the tri-layer element, for example, the second capping layer and the metal gate layer may form a work function layer for one of an nFET and a pFET device. The first capping layer may be a sacrificial layer used to pattern the metal gate layer.

    摘要: A device includes a wafer substrate, a conical frustum structure formed in the wafer substrate, and a gate all-around (GAA) structure circumscribing the middle portion of the conical frustum structure. The conical frustum structure includes a drain formed at a bottom portion of the conical frustum, a source formed at a top portion of the vertical conical frustum, and a channel formed at a middle portion of the conical frustum connecting the source and the drain. The GAA structure overlaps with the source at one side of the GAA structure, crosses over the channel, and overlaps with the drain at another side of the GAA structure.

    摘要: The present disclosure provides a method of fabricating a semiconductor device. A high-k dielectric layer is formed over a substrate. A first capping layer is formed over a portion of the high-k dielectric layer. A second capping layer is formed over the first capping layer and the high-k dielectric layer. A dummy gate electrode layer is formed over the second capping layer. The dummy gate electrode layer, the second capping layer, the first capping layer, and the high-k dielectric layer are patterned to form an NMOS gate and a PMOS gate. The NMOS gate includes the first capping layer, and the PMOS gate is free of the first capping layer. The dummy gate electrode layer of the PMOS gate is removed, thereby exposing the second capping layer of the PMOS gate. The second capping layer of the PMOS gate is transformed into a third capping layer.

    摘要: Compositions, pharmaceutical preparations and methods are disclosed for protecting non-neoplastic cells from damage caused by cancer chemotherapeutic agents or radiation therapy, during the course of cancer therapy or bone marrow transplant. These are based on the use of chemoprotective inducing agents that induce or increase production of cellular detoxification enzymes in target cell populations. The compositions and methods are useful to reduce or prevent hair loss, gastrointestinal distress and lesions of the skin and oral mucosa that commonly occur in patients undergoing cancer therapy. Also disclosed is a novel assay system for identifying new chemoprotective inducing agents.
