Semiconductor device having stacked transistor pairs and method of forming same
摘要:
The disclosed technology generally relates to semiconductor devices and more particularly to a semiconductor device comprising stacked complementary transistor pairs. In one aspect, a semiconductor device comprises first and second sets of transistors comprising a pass transistor and a stacked complementary transistor pair of a lower transistor and an upper transistor, wherein first transistor comprises a semiconductor channel extending along a horizontal first fin track, and each second transistor comprises a semiconductor channel extending along a second fin track parallel to the first fin track, and wherein the semiconductor channels of the pass transistors and of the lower transistors are arranged at a first level and the semiconductor channels of said upper transistors are arranged at a second level, a first tall gate electrode forming a common gate for the first complementary transistor pair and arranged along a horizontal first gate track, and a first short gate electrode forming a gate for the first pass transistor and arranged along a second gate track, a second tall gate electrode forming a common gate for the second complementary transistor pair and arranged along the second gate track, a second short gate electrode forming a gate for the second pass transistor and arranged along the first gate track, first and second contact arrangements forming a common drain contact for the transistors of the first set and the second set, respectively, and first and second cross-couple contacts extending horizontally between and interconnecting the first tall gate electrode and the second contact arrangement, and the second tall gate electrode and the first contact arrangement, respectively.
