摘要:
A semiconductor device including a gate oxide of multiple thicknesses for multiple transistors where the gate oxide thicknesses are altered through the growth process of implanted oxygen ions into selected regions of a substrate. The implanted oxygen ions accelerate the growth of the oxide which also allow superior quality and reliability of the oxide layer, where the quality is especially important, compared to inter-metal dielectric layers. A technique has been used to vary the thickness of an oxide layer grown on a silicon wafer during oxidation growth process by implanting nitrogen into selected regions of the substrate, which the nitrogen ions retard the growth of the silicon oxide resulting in a diminished oxide quality. Therefore it is desirable to fabricate a semiconductor device with multiple thicknesses of gate oxide by the implanted oxygen ion technique.

A CMOS integrated circuit includes a substrate having an NMOS region with a P-well and a PMOS region with an N-well. A shallow trench isolation (STI) region is formed between the NMOS and PMOS regions and a composite silicon layer comprising a strained SiGe layer is formed over said P well region and over said N well region. The composite silicon layer is disconnected at the STI region. Gate electrodes are then formed on the composite layer in the NMOS and PMOS regions.

An ultra thin MOSFET device structure located on an insulator layer, and a method of forming the ultra thin MOSFET device structure featuring a strained silicon channel located on the underlying insulator layer, has been developed. After epitaxial growth of a semiconductor alloy layer such as silicon-germanium (SiGe), on a first semiconductor substrate, a strained silicon channel layer, under biaxial tensile strain, is epitaxially grown on the underlying semiconductor alloy layer. Bonding of the strained silicon channel layer of the first semiconductor substrate, to a silicon oxide layer located on the surface of a second semiconductor substrate, is followed by a cleaving procedure performed at the interface of the strained silicon channel layer and the underlying semiconductor alloy layer, resulting in the desired configuration comprised of strained silicon channel layer-underlying insulator layer-second semiconductor substrate. The MOSFET device is then formed featuring the strained silicon channel layer, on the underlying silicon oxide layer, with enhanced carrier mobility realized as a result of the biaxial tensile strain of the silicon channel layer.

A strained silicon layer fabrication and a method for fabrication thereof employ a strained insulator material layer formed over a strained silicon layer in turn formed upon a strained silicon-germanium alloy material layer which is formed upon a relaxed material substrate. The strained insulator material layer provides increased fabrication options which provide for enhanced fabrication efficiency when fabricating the strained silicon layer fabrication.

A process for fabricating CMOS devices, featuring a channel region comprised with a strained SiGe layer, has been developed. The process features the selective growth of a composite silicon layer on the top surface of N well and P well regions. The composite silicon layer is comprised of a thin, strained SiGe layer sandwiched between selectively grown, undoped silicon layers. The content of Ge in the SiGe layer, between about 20 to 40 weight percent, allows enhanced carrier mobility to exist without creation of silicon defects. A thin silicon dioxide gate insulator is thermally grown from a top portion of the selectively grown silicon layer, located overlying the selectively grown SiGe layer.

摘要:
A process for forming gate oxides of multiple thicknesses. Oxygen is implanted through a sacrificial oxide into selected regions of a silicon substrate according to a patterned photoresist mask. After stripping the sacrificial oxide, a thermal growth process produces a thicker oxide in the implanted regions than in the non-implanted regions. The oxygen-implanted oxide has excellent quality and thickness differentials of up to 20 Å may be obtained with relatively low oxygen implant doses. In an alternative process, a thin gate oxide may be grown prior to a polysilicon layer deposition, and oxygen is then implanted through the polysilicon according to a patterned photoresist mask. After stripping the photoresist, an anneal increases the thickness of the gate oxide in the implanted regions. In another embodiment, a high dielectric constant dielectric layer is deposited on the substrate prior to polysilicon deposition to limit subsequent silicon oxide growth.
