ABSTRACT:
A new shape charge includes an integrated circuit semiconductor bridge detonating device responsive to ordinary current for triggering a switch in the detonating device and igniting a pyrotechnic composition on a small integrated circuit semiconductor bridge in the detonation device in response to the current, thereby igniting an explosive material in the shape charge and firing the shape charge. Since the integrated circuit detonating device is utilized, responsive to ordinary current for detonation, prior art detonating cords are not needed. A plurality of shape charges in a perforating gun are fired substantially simultaneously using the new shape charge of the present invention.
