A semiconductor device comprising a switch and a method of making the same. The device, has a layout having one or more rectangular unit cells. Each unit cell includes a gate having a substantially cross-shaped part comprising four arms that divide the unit cell into quadrants; and a substantially loop-shaped part, wherein a center of the cross-shaped part is located inside the loop-shaped part, and wherein the loop-shaped part intersects each arm of the cross-shaped part to divide each quadrant into an inner region located inside the loop-shaped part; and an outer region located outside the loop-shaped part. Each unit cell also includes a substantially loop-shaped active region forming a source and drain of the switch. Each unit cell further includes a plurality of connection members extending over the gate, source and drain for providing electrical connections to the source and drain.

Semiconductor device comprising a switch

A semiconductor switch device and a method of making the same. The semiconductor switch device includes a field effect transistor located on a semiconductor substrate. The field effect transistor includes a plurality of gates. Each gate includes a gate electrode and gate dielectric arranged in a loop on a major surface of the substrate. The loops formed by the gates are arranged concentrically. Each gate has a source region located adjacent an inner edge or outer edge of the loop formed by that gate and a drain region located adjacent the other edge of said inner edge and said outer edge of the loop formed by that gate.
