The method includes forming a first opening in a dielectric layer overlying the gate electrode and the source/drain region, wherein the first opening extends substantially to the gate electrode corresponding to the first transistor. The method further includes after forming the first opening, forming a second opening, contiguous with the first opening, in the overlying dielectric layer, wherein the second opening extends substantially to the source/drain region corresponding to the second transistor. The method further includes forming the shared contact between the gate electrode corresponding to the first transistor and the source/drain region corresponding to the second transistor by filling the first opening and the second opening with a conductive material.

    摘要: Two different transistors types are made on different crystal orientations in which both are formed on SOI. A substrate has an underlying semiconductor layer of one of the crystal orientations and an overlying layer of the other crystal orientation. The underlying layer has a portion exposed on which is epitaxially grown an oxygen-doped semiconductor layer that maintains the crystalline structure of the underlying semiconductor layer. A semiconductor layer is then epitaxially grown on the oxygen-doped semiconductor layer. An oxidation step at elevated temperatures causes the oxide-doped region to separate into oxide and semiconductor regions. The oxide region is then used as an insulation layer in an SOI structure and the overlying semiconductor layer that is left is of the same crystal orientation as the underlying semiconductor layer. Transistors of the different types are formed on the different resulting crystal orientations.

First spacers (124) are formed on sidewalls of the gate electrode (120). First s/d trenches (130) are formed in the substrate (102) using the gate electrode (120) and first spacers (124) as a mask. The first s/d trenches (130) are filled with a first s/d structure (132). Second spacers (140) are formed on the gate electrode (120) sidewalls adjacent the first spacers (124). Second s/d trenches (150) are formed in the substrate (102) using the gate electrode (120) and the second spacers (140) as a mask. The second s/d trenches (150) are filled with a second s/d structure (152). Filling the first and second s/d trenches (130, 150) preferably includes growing the s/d structures using an epitaxial process.
