Claim:
1. A lateral diffusion field effect transistor and an associated control circuit comprising: a source region of doped semiconductor material that is electrically coupled to a metallic source contact; a first doped drain region of doped semiconductor material that has a lower dopant concentration than the source region; a second doped drain region of doped semiconductor material that: (1) forms an electrically conductive path between the metallic drain contact and the first doped drain region; and (2) has a higher dopant concentration than the first doped drain region; a channel that separates the source region and the first doped drain region; a gate electrode located above the channel and separated from the channel by a gate dielectric; and a shield plate located above the gate electrode and the first doped drain region, and separated from the first doped drain region, the gate electrode, and the source contact by an interlayer dielectric; wherein the control circuit includes a delay circuit, is integrated on a monolithic substrate with the lateral diffusion field effect transistor, and:
