    摘要: A solid state detonator is made using a silicon chip with appropriate surnding sections to provide the resistance path necessary to detonate a primary explosive. The chip is set on a metal-to-glass-to-metal header to provide uniformity of current and insulation capabilities. A gold mesh is used as a conductor connected to a chromium-silicon resistor film. This provides a uniform annular heating ring for detonation purposes. The silicon chip may be doped for high conductivity and low resistance. This arrangement provides fast function with moderate power pulses while the thermal design permits high no-fire current levels.
