Claim 8:
9. A load switch comprising:
a first transistor; and
a second transistor being back-to-back connected to the first transistor, wherein:
a source of the first transistor and a source of the second transistor are formed over a substrate;
a gate of the first transistor is adjacent to the source of the first transistor;
a gate of the second transistor is adjacent to the source of the second transistor, wherein the gate of the first transistor and the gate of the second transistor are separated from each other, and wherein bottommost surfaces of the gate of the first transistor and the gate of the second transistor are over a top surface of the substrate;

a high voltage oxide region, wherein from a top view, a first edge of the high voltage oxide region is aligned with a middle line of the gate of the first transistor, and a second edge of the high voltage oxide region is aligned with a middle line of the gate of the second transistor; and
an active region formed between the source of the first transistor and the source of the second transistor, wherein from the top view, the active region is orthogonal to the high voltage oxide region.
