Abstract:
An electro-explosive device for initiating detonation of an adjacent pyrotechnic mixture, said electro-explosive device comprising:a semiconductor substrate having a top surface and a bottom surface;a layer of insulating material formed on said top surface of said substrate;a cavity formed in said top surface of said substrate, said cavity extending through said layer of insulating material and extending a predetermined distance into said substrate, said cavity having interior walls;a first layer of conducting material formed on and covering said layer of insulating material and said interior walls of said cavity; anda second layer of conducting material formed on and covering said bottom surface of said substrate;said first and second layers of conducting material being electrically connectable to a source of current sufficient to flow through said second layer of conductive material, through said substrate, and through the portion of said first layer of conductive material covering said interior walls of said cavity to explode the conducting material within said cavity in a plasma to ignite a pyrotechnic mix disposed adjacent said device.
