Hepfinger","doi":"10.1109/ISPSD.1999.764046","DOIUrl":"https://doi.org/10.1109/ISPSD.1999.764046","url":null,"abstract":"The trade-off between breakdown voltage and on-resistance is a well-known feature of both lateral and vertical DMOS transistors. The trade-offs and restrictions imposed by the \"safe operating area\" are less familiar. The SOA defines limits on the excursion of the operating point in the I/sub d/-V/sub ds/ plane. To be correct, the SOA should also include thermal limitations; however, these can be treated separately. In this paper, we focus on the \"electrical SOA\", which is defined by a specific boundary line in the I/sub d/-V/sub ds/ plane. Although the LDMOS SOA has been discussed in a number of papers, the details of the device physics that determine the SOA boundary are still somewhat unclear and further work is needed. The main purpose of this paper is to investigate device behaviour in the neighborhood of the SOA boundary and then use these results to predict the SOA. We consider devices with and without drain extensions using a self-aligned body diffusion. The predicted SOA is shown to be in good agreement with measurements for both types of LDMOS. Current flow within the device is examined in detail. The observed SOA is shown to be consistent with the silicon power density limit, a fundamental characteristic of silicon devices. Finally, we show how a simplified two-terminal model of the drain region can be used to demonstrate the behaviour of the LDMOS as it approaches snap-back. This approach is analogous to that previously used to model the onset of avalanche initiated second breakdown in bipolar transistors (hower and Reddi, 1970).","PeriodicalId":352185,"journal":{"name":"11th International Symposium on Power Semiconductor Devices and ICs.

The implementation of the SW structure is straightforward with low cost. It is expected that the source exclusion mask can be removed. When compared to a conventional VDMOST with the same design rules, the SW device provides 15% lower R/sub sp/ and 10% lower Q/sub rr/ without degradation of device ruggedness. In addition, it is expected that the SW device will yield higher hot-carrier reliability.","PeriodicalId":352185,"journal":{"name":"11th International Symposium on Power Semiconductor Devices and ICs.

Power management issues for future generation microprocessors 下一代微处理器的电源管理问题

The current generation of high-speed CMOS processors (e.g. Alpha, Pentium, Power PC) are operating at above 300 MHz with 2.5 to 3.3 V output range. Future processors will be designed in the 1.1-1.8 V range to further enhance their speed-power performance. These new generations of microprocessors will present very dynamic loads with high current slew rates during transients. As a result, they will require a special power supply, a voltage regulator module (VRM), to provide well-regulated voltage. The VRMs should have high power densities, high efficiencies, and good transient performance. This paper addresses the critical technical issues to achieve this target for future generation microprocessors.","PeriodicalId":352185,"journal":{"name":"11th International Symposium on Power Semiconductor Devices and ICs.

We have fabricated both PT and transparent anode NPT devices to cover a wide range of applications which require very low on-state losses or very fast time with ultra-low switching losses. The minimum forward voltage drop at the standard current density of 100 A/cm/sup 2/ was 1.1 V for PT nonirradiated devices and 2.1 V for 16 MRad PT irradiated devices. The nonirradiated transparent emitter NPT structure has a typical forward voltage drop of 2.2 V, a turn-off time below 100 ns and turn-off energy losses of 11.2 mW/cm/sup 2/ at 125 C.
