    摘要: This description relates to a method including forming an interlayer dielectric (ILD) layer and a dummy gate structure over a substrate and forming a cavity in a top portion of the ILD layer. The method further includes forming a protective layer to fill the cavity. The method further includes planarizing the protective layer. A top surface of the planarized protective layer is level with a top surface of the dummy gate structure. This description also relates to a semiconductor device including first and second gate structures and an ILD layer formed on a substrate. The semiconductor device further includes a protective layer formed on the ILD layer, the protective layer having a different etch selectivity than the ILD layer, where a top surface of the protective layer is level with the top surfaces of the first and second gate structures.

    摘要: The present disclosure provides a system for in-situ spectrometry. The system includes a wafer-cleaning machine that cleans a surface of a semiconductor wafer using a cleaning solution. The system also includes a spectrometry machine that is coupled to the wafer-cleaning machine. The spectrometry machine receives a portion of the cleaning solution from the wafer-cleaning machine. The portion of the cleaning solution collects particles from the wafer during the cleaning. The spectrometry machine is operable to analyze a particle composition of a portion of the wafer based on the portion of the cleaning solution, while the wafer remains in the wafer-cleaning machine during the particle composition analysis.

In an example, a gate stack disposed over a semiconductor substrate includes an interfacial dielectric layer disposed over the semiconductor substrate, a high-k dielectric layer disposed over the interfacial dielectric layer, a first conductive layer disposed over the high-k dielectric layer, and a second conductive layer disposed over the first conductive layer. The first conductive layer includes a first metal layer disposed over the high-k dielectric layer, a second metal layer disposed over the first metal layer, and a third metal layer disposed over the second metal layer. The first metal layer includes a material that scavenges oxygen impurities from the interfacial dielectric layer, and the second metal layer includes a material that adsorbs oxygen impurities from the third metal layer and prevents oxygen impurities from diffusing into the first metal layer.
