Abstract
An electro-explosive device is provided for detonating a pyrotechnic mix disposed adjacent the device to initiate an explosion. The device comprises a silicon wafer semiconductor substrate having a top surface and a bottom surface. The top surface of the substrate is covered with an insulating layer and a cavity is formed through the insulating layer a predetermined distance into the substrate. A first layer of conducting material covers the insulating layer and the interior walls of the cavity and a second layer of conducting material covers the bottom surface of the substrate. A primary explosive material is packed in the cavity. When the first and second layers of conducting material are coupled to a source of electric current, the current flows into the conducting material lining the walls of the cavity causing it to explode through ohmic heating in a plasma, thus igniting the primary explosive material within the cavity. The resulting energy is projected from the cavity in a shaped, relatively collimated pattern to detonate a pyrotechnic mix disposed adjacent the device.
