Abstract: The invention discloses a treatment process for a semiconductor, comprising providing a substrate, the substrate comprises silicon material; defining a trench region; removing the trench region using a plasma etching process and exposing a trench surface, the trench surface comprising surface defects; forming an oxidation layer overlaying the trench surface; removing the oxidation layer and at least a portion of the surface defects; expositing a treated trench surface, the treated trench surface being substantially free from surface defects; and forming a layer of silicon germanium material overlaying the treated trench surface. The invention further provides a semiconductor processing technique used to eliminate or reduce dislocation defect on the semiconductor device and improve device performance. In the treatment process, a substrate is subjected to at least one oxidation-deoxidation processes, where an oxidation layer is formed and then removed.

Abstract: A process is used to form a protective layer to cover a divot between two regions of a semiconductor material. During etching processes, the protective layer protects the divot to be etched away and reduces material loss of a Silicon (Si)-shallow trench isolation (STI) substrate. A selective coverage is provided to protect the height of the Si-STI substrate and an Si-STI interface. A desirable geometry can be obtained for forming a silicon germanium (SiGe)layer with uniform thickness near the divot.

Abstract: The invention relates to microelectronic technology and, more specifically, relates to a method of forming a gate with a LELE double pattern. The method adopts an ONO structure (Oxide-SiN-Oxide). The ONO structure is exposed twice, and the advanced patterning film is used as a mask in the processing of polysilicon etching. The ONO structure is used to replace the traditional hardmask of silicon oxide, and the substructure of ODL (Organic Under Layer) which is based on the spin-on, and the middle layer structure of SHB (Si-based hardmask). The method saves cost and improves the process of advanced patterning film as a mask with the nodes in 40 nm and above which is applied to the process with the nodes in 22/20 nm and below. Consequently, the maturity and stability of the process for poly gate with the nodes in 22/20 nm and below are improved.
