Semiconductor bridge (SCB) initiator represents a novel one kind of initiating device. It has been developed very rapidly due to its excellent properties, such as its high safety, high reliability, high synchronization, a high coherence of technologies, low fire energy and its readiness of incorporation with the digital logic circuits. In this paper are reviewed the theory, configuration, packing, test and improvement of SCB initiators and its future prospects. In addition, it is pointed out that semiconductor bridge (SCB) initiator is the ideal substitute for the bridge initiating device and has more extensive area of application. The key point in its future development lies in the basic theory, the automatization of production, ignition by low voltage and passivated technology of in line explosives.
