Webdiscussed further in Chapter 2. There is also the possibility of latch-up due to the internal PNPN thyristor structure [3]. This will also be discussed further in Chapter 2. While the first commercially available IGBTs did not exceed blocking voltages up to 600V, and currents of a few amperes, development started aimed at increasing the power Webevolution in the IGBT. Through the previous physical mechanism, we propose a systematic methodology to clarify the failure mechanism origin. This methodology is summed up in figure 2.

Web26 mrt. 2009 · Latch-up in CMOS ICs is preventable. Simple circuit techniques and attention to system design details will ensure that the CMOS' full potential can be realized in all operating environments. Designers can also look forward to the day, in the not too distant future, when even these few simple precautions will no longer be necessary. Synopsis Web3.1.1 Latch-up In this case, the avalanche event generates a drain current, the amplitude of which will be greater where the electric field has greater intensity. Latch-up is a consequence of the parasitic NPN bipolar junction transistor (BJT) that resides within power MOSFETs. If the device technology is structured in such a way that the electric

The metal–oxide–semiconductor field-effect transistor (MOSFET) was invented by Mohamed M. Atalla and Dawon Kahng at Bell Labs in 1959. The basic IGBT mode of operation, where a pnp transistor is driven by a MOSFET, was first proposed by K. Yamagami and Y.
