  • SEMICONDUCTOR STRUCTURE HAVING METAL GATE AND FORMING METHOD THEREOF
    Publication number: 20190371916
    Abstract: A semiconductor structure having a metal gate includes a dielectric layer. The dielectric layer having a recess is disposed on a substrate, wherein the dielectric layer has a top part and a bottom part, and the tensile stress of the top part is larger than the tensile stress of the bottom part, thereby the recess having a sidewall profile tapering from bottom to top. The present invention also provides a method of forming said semiconductor structure.
