The device features a conventional planar DMOS cell design. To compensate for the lack of injection enhancement at the cathode, the n-base width is minimized for the required blocking voltage employing a punchthrough design. To avoid the problems related to anode shorts embedded in highly conductive stopping layers, low injection efficiency of the p+emitter at the anode is realized with a homogeneous, transparent emitter layer. The properties of the emitter and buffer layers determine the injection efficiency of the anode and the electrical characteristics of the high voltage IGBTs. Experimental devices were demonstrated switching inductive loads at up to 70 A/cm/sup 2/ at 3 kV without using snubbers. These devices have short circuit ruggedness and endure peak power densities of 2 MW/cm/sup 2/ for several microseconds.","PeriodicalId":377997,"journal":{"name":"8th International Symposium on Power Semiconductor Devices and ICs.

This paper reports an EBIC analysis of the experimentally obtained results for three termination techniques: (a) Floating Metal field Ring (FMR) (b) REsistive Schottky barrier field Plate (RESP) (c) Argon Ion Implant termination. Argon Ion Implant termination was found to be most effective in spreading the depletion boundary at the surface. EBIC analysis on the RESP terminated diodes revealed that insufficient sheet resistance of the RESP layer caused an early breakdown in these diodes. FMR terminated diodes exhibited spreading of the depletion region beyond that indicated by numerical simulations without surface charge. Simulations performed to study the effect of negative surface charge indicate that a charge density of more than 1/spl times/10/sup 11/ cm/sup -2/ was required to cause substantial spreading of the depletion edge.","PeriodicalId":377997,"journal":{"name":"8th International Symposium on Power Semiconductor Devices and ICs.

The design of the device and a proposed fabrication-process is discussed. The new device has the robust qualities of the IGBT (current saturation, homogeneous current distribution, insulated gate control), and the four-layer thyristor structure allows for a strong reduction in losses compared to the IGBT. A comparison by simulation for high-voltage devices shows that the losses can be reduced by a factor of 2-3 at 3 kV switching and by a factor of 4 at 6 kV switching, as compared to an optimized planar IGBT structure. We also show simulations comparing the stability of these devices against dynamic avalanche-induced current filamentation instabilities.","PeriodicalId":377997,"journal":{"name":"8th International Symposium on Power Semiconductor Devices and ICs.

A SPICE circuit model using spherical spreading of heat through silicon is developed to predict the transient thermal behavior of the LDO regulator. Simulations indicate a 65 mV drop in the output regulated voltage for a power pulse of 1.4 W through the output power transistor and are in excellent agreement with that obtained from experiments.
