Patent ID: 7915713

Claim:
An integrated circuit, comprising: a first field effect transistor comprising a first channel oriented to one of a first set of equivalent crystal planes of a semiconductor substrate, the first set being parallel to a main surface of the semiconductor substrate; and a second field effect transistor comprising a second channel at least a portion of which is oriented to a second set of parallel crystal planes of the semiconductor substrate, the second set being tilted with reference to the main surface, the second field effect transistor being separated from the first field effect transistor by an isolation structure in a first cross-section that is perpendicular to the main surface and that extends along a first direction extending between the first and second channels; wherein the second channel is configured to provide a path for current flow between first and second source/drain regions of the second field effect transistor in a second direction perpendicular to the first cross-section and parallel to the intersection lines of the first and second sets of parallel crystal planes; and wherein the first channel configured to provide a path for current flow between first and second source/drain regions of the first field effect transistor in the second direction such that the first and second channels are configured to provide paths for current flow along a same crystal axis but on crystal planes of different orientation.
