Abstract:
1. A method of manufacturing an integrated circuit on semiconductor substrates, the method comprising: providing a semiconductor substrate characterized by a first lattice with a first structure and a first spacing, the semiconductor substrate having 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 first tensile mode and/or compressive mode along the film surface crystal axes across a portion of the film of material relative to the semiconductor substrate with the first structure and the first spacing; and patterning a predetermined region in a portion of the film of material to cause the first tensile mode to change to a second tensile mode in the patterned predetermined region if the portion of the film of material is in the first tensile mode or to cause the first compressive mode to change to a second compressive mode in a patterned predetermine region if the portion of the film of material is in the first compressive mode.
