    摘要: A method of performing an ultraviolet (UV) curing process on an interfacial layer over a semiconductor substrate, the method includes supplying a gas flow rate ranging from 10 standard cubic centimeters per minute (sccm) to 5 standard liters per minute (slm), wherein the gas comprises inert gas. The method further includes heating the interfacial layer at a temperature less than or equal to 700° C. Another method of performing an annealing process on an interfacial layer over a semiconductor substrate, the second method includes supplying a gas flow rate ranging from 10 sccm to 5 slm, wherein the gas comprises inert gas. The method further includes heating the interfacial layer at a temperature less than or equal to 600° C.

    摘要: A method includes performing a first probing on a sample integrated circuit structure to generate a first Raman spectrum. During the first probing, a first laser beam having a first wavelength is projected on the sample integrated circuit structure. The method further includes performing a second probing on the sample integrated circuit structure to generate a second Raman spectrum, wherein a Tip-Enhanced Raman Scattering (TERS) method is used to probe the sample integrated circuit structure. During the second probing, a second laser beam having a second wavelength different from the first wavelength is projected on the sample integrated circuit structure. A stress in a first probed region of the sample integrated circuit structure is then from the first Raman spectrum and the second Raman spectrum.

    摘要: A multi-layer scavenging metal gate stack, and methods of manufacturing the same, are disclosed. 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.
