Patent attributes
A semiconductor device includes first to fourth semiconductor fins, a first gate structure, and a second gate structure. The first and second semiconductor fins are substantially aligned along a first direction. The third and fourth semiconductor fins are substantially aligned along the first direction. The third and fourth semiconductor fins have a conductivity type different from that of the first and second semiconductor fins. The first gate structure extends across the first and third semiconductor fins substantially along a second direction. The second gate structure extends across the second and fourth semiconductor fins substantially along the second direction. The first and fourth semiconductor fins are substantially aligned along a third direction crossing the first and second directions, and the third direction is substantially parallel with a <100> crystallographic direction.
