zum Thema:

„Simulation, Measurement and Lowering of Self-Heating in Power Semiconductors”


Power semiconductors are often subject to high power dissipation and thus substantial self-heating. This limits their safe operating area because very high device temperatures can lead to thermal runaway and subsequent destruction. We will discuss how device temperatures can be accurately measured and predicted to avoid oversizing and to fully exploit the potential of modern technologies. We will also show how peak temperatures can be lowered solely by layout modifications, allowing for substantial chip size reductions.
