Abstract: A device comprises a reactive semiconductor bridge including a conductive metal, a reactive material, and an overcoat. When a high current passes through the reactive semiconductor bridge, the conductive metal vaporizes into a high temperature plasma. The reactive material is coupled to the conductive metal such that the conductive metal experiences an exothermic reaction to the plasma. When the conductive metal turns to plasma, the overcoat material absorbs at least a part of the exothermic reaction of the reactive material and breaks into a plurality of particles that are propelled away from the bridge. A gap is disposed between the overcoat and a membrane, and an explosive material couples to the membrane. The plurality of particles crosses the gap and penetrates the membrane to ignite the explosive material in response to being propelled away from the bridge.
