    摘要: A method for performing grinding includes selecting a target wheel loading for wafer grinding processes, and performing a grinding process on a wafer. With the proceeding of the grinding process, wheel loadings of the grinding process are measured. The grinding process is stopped after the target wheel loading is reached. The method alternatively includes selecting a target reflectivity of wafer grinding processes, and performing a grinding process on a wafer. With a proceeding of the grinding process, reflectivities of a light reflected from a surface of the wafer are measured. The grinding process is stopped after one of the reflectivities reaches the target reflectivity.

    摘要: A semiconductor device and a method of manufacturing are provided. A dielectric layer is formed over a substrate, and a first silicon-containing layer, undoped, is formed over the dielectric layer. Atomic-layer doping is used to dope the undoped silicon-containing layer. A second silicon-containing layer is formed over first silicon-containing layer. The process may be expanded to include forming a PMOS and NMOS device on the same wafer. For example, the first silicon-containing layer may be thinned in the PMOS region prior to the atomic-layer doping. In the NMOS region, the doped portion of the first silicon-containing layer is removed such that the remaining portion of the first silicon-containing layer in the NMOS is undoped. Thereafter, another atomic-layer doping process may be used to dope the first silicon-containing layer in the NMOS region to a different conductivity type. A third silicon-containing layer may be formed doped to the respective conductivity type.
