Power devices, or more specifically “solid state electrical devices” are used to control electric power. Silicon semiconductors have been employed in power circuits since the invention of the solid state diode by William Shockley in 1960. Today the discrete power device market has achieved a size of nearly 20 billion USD with a predicted CAGR of ~7%. This continuous growth is driven by the ever-increasing needs for energy management and control in domestic and industrial markets, mobile communication/computing and most recently by greenhouse gas reduction initiatives. Electric vehicles like cars and trains as well as renewable energy generation looks set to spur the major part of power device development and growth.
