Silicon semiconductor devices are typically rated for a maximum junction operating temperature. Exceeding this temperature can lead to permanent damage, such as diffusion of dopants, breakdown of insulating layers, or thermal runaway, which results in irreversible changes to the device's structure and characteristics. For standard silicon devices (like those based on bipolar junctions or CMOS technology), the maximum allowable junction temperature is commonly around 150°C.
Silicon is one of the best known semi conducting material. As its temperature rises more, it becomes a better conductor. But the temperature at which the silicon gets permanently damaged is
