Abstract
A semiconductor device is provided. The device includes a first pair and a second pair of source/drain features over a semiconductor substrate. The first pair of source/drain features are p-type doped. The second pair of source/drain features are n-type doped. A first stack of semiconductor layers connect the first pair of source/drain features along a first direction. A second stack of semiconductor layers connect the second pair of source/drain features along a second direction. A first gate is between vertically adjacent layers of the first stack of semiconductor layers. The first gate has a first portion that has a first dimension along the first direction. A second gate is between vertically adjacent layers of the second stack of semiconductor layers. The second gate has a second portion that has a second dimension along the second direction. The second dimension is larger than the first dimension.
