Definitions

  • This invention generally relates to an electro-explosive device. More particularly, the. invention relates to a device having a laminate bridge that initiates a reaction of relatively high output energy for relatively low input energy.
  • an electro-explosive device receives electrical energy and initiates a mechanical shock wave and/or an exothermic reaction, such as combustion, deflagration, or detonation.
  • EEDs have been used in both commercial and government applications for a variety of purposes, such as to initiate the inflation of airbags in automobiles or to activate an energy source in an ordnance system.
  • Prior art EEDs include those that use a bridgewire to ignite an ordnance material.
  • a bridgewire is a thin resistive wire attached between two contacts. The ordnance material surrounds the bridgewire. When current is passed through the bridgewire ohmic heating results. When the bridgewire reaches the ignition temperature of the ordnance material, the ordnance material initiates.
  • the ordnance material is a primary or pyrotechnic charge which ignites a secondary charge, which in turn ignites a main charge.
  • EEDs that use a bridgewire have significant disadvantages in modem applications. For example, EEDs are subjected to increasing levels of electromagnetic interference (EMI) in many military and civilian applications.
  • EMI electromagnetic interference
  • EEDs may also be unintentionally fired by electrostatic discharge (ESD).
  • ESD electrostatic discharge
  • the total energy of the firing signal which is necessary to ignite the EED may be increased.
  • low level stray signals may be conducted through the bridgewire without causing any ignition and only the higher level firing signal would have sufficient energy to ignite the EED.
  • a higher magnitude firing signal is not always desirable.
  • available power is severely limited, making it necessary to provide an EED that has a low firing energy, which may be near the energy level of potential spurious signals such as those from ESD or EMI sources.
  • An SCB may use less energy than that used by a bridgewire EED for the same no-fire level.
  • the energy required by an SCB may be an order of magnitude less than that required by a bridgewire device with the same no-fire performance.
  • An SCB is a ordnance material initiating device built on a semiconductor substrate. The SCB typically ignites the ordnance material with a hot plasma. When the SCB fires, it creates a high temperature plasma (for example, greater than 4000 degrees K in some cases) with high power density that ignites the ordnance material.
  • the SCB may generate plasma in less than several microseconds as compared to the bridgewire, which may heat to the point of initiation in hundreds of microseconds.
  • the ordnance material ignited by the SCB is typically an adjacent ordnance material or primary explosive that is ignited in a matter of microseconds and in turn ignites an output charge.
  • the excellent heat transfer characteristics of the semiconductor provide a high capacity heat sink for the SCB and thus a relatively high no-fire level.
  • an SCB should be driven by a low impedance voltage source or a capacitive discharge to properly support an avalanche condition that results in plasma creation.
  • EEDs used in automobile airbags and other safety critical applications presents several problems in addition to the prevention of unintentional firing.
  • the reliability of an airbag EED is- critical.
  • the airbag EED must fire reliably, and must be manufactured in a way that ⁇ allows some verification of reliability.
  • Conventional SCBs have some disadvantages that make it difficult to produce verifiably reliable SCB EEDs.
  • SCBs provide a very hot but low energy ignition source that lasts only for microseconds. In typical SCBs the amount of energy output is dependent upon, and is less than, the level of energy input. In cases in which only a very small amount of output energy can be produced, the output energy may not be sufficient to provide reliable ignition.
  • a semiconductor bridge (SCB) device on a substrate with a laminate bridge comprises multiple, alternating layers of a thermally and electrically insulating material and a conducting material that is exothermically reactive with the insulating material.
  • the multiple alternating layers form a laminate layer on an insulator on the surface area of the substrate.
  • the substrate is silicon.
  • boron is the insulating material and titanium is the conductive material.
  • the laminate layer is typically continuous. In a top view, however, the laminate layer appears as two large sections that substantially cover the surface area of the substrate and are joined by a bridge section.
  • the bridge section has a small cross-sectional area relative to the direction of current flow.
  • the laminate layer is constructed as a series of individual, alternating insulating and reactive layers.
  • the bridge section is reacted when current is passed through contacts on top of the laminate, which initiates the remainder of the laminate.
  • the output energy produced is sufficient to ignite ordnance material across a gap.

Thus, the diodes appear to ESD induced potentials as closed circuit shunts and electric current above the shunt threshold is conducted away from the resistive bridge to prevent ohrnic heating of the bridge and consequent accidental firing.

  • the SCB 90 provides reliable ignition across a gap between the bridge and the ordnance material. This greatly enhances reliability because an intimate interface between the bridge and the ordnance material does not need to be guaranteed for proper operation. Verification of the interface between the bridge and ordnance material is thus not required. It is only necessary to verify, using conventional techniques, that the semiconductor wafer has been correctly processed. The presence of an output charge may be easily verified by weighing or x-ray.
