发明名称 Method for fabricating semiconductor devices using strained silicon bearing material
摘要 A method of manufacturing an integrated circuit on semiconductor substrates, e.g., silicon wafer. The method includes providing a semiconductor substrate characterized by a first lattice with a first structure and a first spacing. In a specific embodiment, the semiconductor substrate has an overlying film of material with a second lattice with a second structure and a second spacing, the second spacing placing the film of material in a strain mode characterized by a first tensile and/or compressive mode along a single film surface crystal axis across a first portion of the film of material relative to the semiconductor substrate with the first structure and the first spacing. The method patterns a predetermined region of the first portion of the film of material to cause the first tensile and/or compressive mode in the first portion of the film of material to change to a second tensile and/or compressive mode in a resulting patterned portion of the first portion of the film of material. In a preferred embodiment, the patterns are made using a masking and etching process.
