Abstract
The invention relates to FETs with stripe cells (). Some of the cells have alternating low and high threshold regions () along their length. In a linear operations regime, the low threshold regions conduct preferentially and increase the current density, thereby reducing the risk of thermal runaway. By distributing the low threshold regions () along the length of the cells (), the risk of current crowding is reduced.
