    摘要: A semiconductor device includes a semiconductor substrate and a trench isolation. The trench isolation is located in the semiconductor substrate, and includes a first cushion layer, a second cushion layer and an insulating filler. The first cushion layer is peripherally enclosed by the semiconductor substrate, the second cushion layer is peripherally enclosed by the first cushion layer, and insulating filler is peripherally enclosed by the second cushion layer. A method for fabricating the semiconductor device is also provided herein.

    摘要: Embodiments of cleaning a surface of a polysilicon layer during a chemical mechanical polishing (CMP) process are provided. The method includes providing a substrate, and forming a gate structure on the substrate, and the gate structure includes a polysilicon layer. The method further includes forming an inter-layer dielectric layer (ILD) over the gate structure. The method also includes performing a CMP process to planarize the inter-layer dielectric layer (ILD) and to expose the polysilicon layer, and the CMP process includes: providing an oxidation solution to a surface of the substrate to perform an oxidation operation to form an oxide layer on the polysilicon layer; and providing a cleaning solution to the surface of the substrate to perform a cleaning operation.
