ABSTRACT:
An explosive detonator consisting of an integrated circuit chip having a silicon substrate on which is formed an amorphous or polysilicon bridge, the bridge extending between two metal wire-bonding pads also on the substrate. The integrated circuit chip is disposed in close proximity to a primary charge such that when the bridge is energized by an electric current, it heats to the point where the charge is ignited. By back-etching the silicon substrate under the bridge, parasitic heat conduction is avoided. Further, by bonding a pyrex tube to the chip with the tube's bore surrounding the bridge, it is possible to pack the bore with an explosive train in fabricating the detonator assembly.
