Patent ID: 8291824

Claim:
A monolithic exploding foil initiator, comprising: a header comprising a first feedthrough pin and a second feedthrough pin that are electrically isolated from each other and that penetrate an insulator element of the header, the insulator element having a top surface; an initiator metal structure comprising a bridge layer affixed to the top surface of the insulator element, the bridge layer comprising a bridge metal layer and having a pattern comprising a first pad region, a second pad region, and a bridge connecting the first pad region and the second pad region, wherein the first pad region is in electrical contact with the first feedthrough pin and the second pad region is in electrical contact with the second feedthrough pin and further comprising a first conductive pad atop the first pad region and a second conductive pad atop the second pad region; and a dielectric layer covering at least the bridge of the initiator metal structure, the dielectric layer having a thickness suitable for ejection of a flyer upon passage of an actuating current through the bridge.
