摘要: A method of manufacturing a semiconductor device includes the formation of an oxide spacer layer to modify the critical dimension of a gate cut opening in connection with a replacement metal gate process. The oxide spacer layer is deposited after etching a gate cut opening in an overlying hard mask such that the oxide spacer layer is deposited onto sidewall surfaces of the hard mask within the opening and directly over the top surface of a sacrificial gate. The oxide spacer may also be deposited into recessed regions within an interlayer dielectric located adjacent to the sacrificial gate. By filling the recessed regions with an oxide, the opening of trenches through the oxide spacer layer and the interlayer dielectric to expose source/drain junctions can be simplified.

摘要: A shallow trench isolation (STI) structure is formed from a conventional STI trench structure formed of first dielectric material extending into the substrate. The conventional STI structure undergoes further processing, including removing a first portion of the dielectric material and adjacent portions of the semiconductor substrate to create a first recess, and then removing another portion of the dielectric material to create a second recess in just the dielectric material. A nitride layer is formed above remaining dielectric material and on the sidewalls of the substrate. A second dielectric material is formed on the spacer layer and fills the remainder of first and second recesses. The nitride layer provides an “inner spacer” between the first insulating material and the second insulating material and also separates the substrate from the second insulating material. An isotropic Fin reveal process is performed and the STI structure assists in equalizing fin heights and increasing active S/D region area/volume.

摘要: Semiconductor devices and fabrication methods are provided. In a semiconductor device, a semiconductor substrate includes a first electrode layer having a top surface coplanar with a top surface of the semiconductor substrate. A sacrificial layer is formed on the semiconductor substrate and the first electrode layer. A first mask layer made of a conductive material is formed on the sacrificial layer. The first mask layer and the sacrificial layer are etched until a surface of the first electrode layer is exposed to form openings through the first mask layer and the sacrificial layer. A cleaning process is performed to remove etch byproducts adhered to a surface of the first mask layer and adhered to sidewalls and bottom surfaces of the openings. Conductive plugs are formed in the openings after the cleaning process.
