I paid my way through college hand-making electronics boards for professors and 
engineers.

All semiconductors have a lifetime that is measured by the area under the curve 
of their temperature over time. The doping in the semiconductor gradually 
diffuses through the semiconductor, the rate of diffusion increases as the 
temperature rises. Once the differently doped parts "collide" the semiconductor 
fails.
