Opportunity:
Lawrence Livermore National Laboratory (LLNL), operated by the Lawrence Livermore National Security (LLNS), LLC under contract no. DE-AC52-07NA27344 (Contract 44) with the U.S. Department of Energy (DOE), is offering the opportunity to enter into a collaboration to further develop its Semiconductor Open Switch with pre-pulses elimination.
Background:
A Semiconductor Opening Switch (SOS) is a high-power pulse diode designed to interrupt currents at density levels of up to 10 kA/cm2 in less than 10 nanoseconds. Current state of the art SOSs are widely used as solid-state generators to produce high power laser light, x-rays, and neutron pulses. One of their drawbacks however is that their performance is compromised by the presence of pre-pulses. These unwanted pulses feature long duration time and slow rise time, which degrades the voltage pulse rise time, peak voltage, etc. of the SOS device. There is a need for a different SOS device structure that is able to suppress or eliminate these pre-pulses.
Description:
LLNL developed a novel SOS diode structure starting with a n-type silicon wafer. On the appropriate sides of the wafer, donor and acceptor dopants with specifically designed and optimized concentration profiles are diffused in the structure. Crucially, an extra n-region is introduced to the structure to address pre-pulses. The result is a SOS diode with an optimized p+/p/n-base/n+ structure, and an extra layer that has a gradient n-doping. The incorporation of this layer effectively suppresses the pre-pulses, increases peak voltage and reduces pulse rise time. This approach has been validated in optimization simulations.
Advantages/Benefits:
Value Proposition: Improved performance of SOS diodes Vital for compact high voltage pulse generators
Potential Applications:
Pulsed-power physics Compact high voltage pulse generators High power electronics
Development Status:
