Description

Technical Field

[0002] A field-effect transistor (FET) is a semiconductor device that uses the electric field effect of the input circuit to control the current in the output circuit. FETs are unipolar transistors, meaning that almost only one type of charge carrier moves during conduction, similar to metal conduction. Compared to bipolar transistors (BPTs), FETs have advantages such as smaller size, lighter weight, and longer lifespan. They also have particularly high input circuit internal resistance, low noise, good thermal stability (because they almost exclusively utilize majority carrier conduction), strong radiation protection, and energy efficiency. FETs dominate the market. However, when installing FETs, heat sinks are required. In existing technologies, heat sinks are mostly connected to FETs using bolts, which is inconvenient and can easily damage the FET if the bolts are tightened too much. Therefore, this invention proposes a quick-installation structure for heat sinks of FETs in integrated circuits. Utility Model Content
