An RF-insensitive semiconductor slapper ignitor is created using a silicon ubstrate having a first metallized portion centrally located on its bottom face to form a Schottky barrier diode thereon, and a second substantially smaller metallized portion centrally located on its top face to form a consumable plug. A flyer disc is disposed atop the second metallized portion and is propelled when the consumable plug vaporizes in response to the high current density associated with ignition. In various embodiments the flyer disc is either an insulating material such as plastic, or polyimide, or formed integral to a top contact metal layer.

Semiconductor slapper

An RF-insensitive semiconductor ignitor and primer cup assembly is created sing a double polished n-type silicon substrate having its top and bottom surfaces partially metallized to form Schottky barrier diodes. The metallized portion of the back side of the substrate is placed in contact with a conductive surface, and means are provided to electrically isolate those portions of the substrate which have not been metallized from both the metallized portions and the conductive surface. In one embodiment, the isolating means is an integral oxide ring which extends from the periphery of the contact metal to the edge of the substrate. In another embodiment, the means of isolation is a separate plastic ring.
