Abstract
A system and method for creating layout for standard cells are described. In various implementations, a standard cell uses Cross field effect transistors (FETs) that include vertically stacked gate all around (GAA) transistors with conducting channels oriented in an orthogonal direction between them. The direction of current flow of the top GAA transistor is orthogonal to the direction of current flow of the bottom GAA transistor. The channels of the vertically stacked transistors use opposite doping polarities. The orthogonal orientation allows both the top and bottom GAA transistors to have the maximum mobility for their respective carriers based on their orientation. The Cross FETs utilize a single metal layer and a single via layer for connections between the top and bottom GAA transistors.
