Abstract (en)

[origin: DE19755868C1] The transistor has a semiconductor thin layer (3) of one conductive type. This is embedded in an insulating layer (2) arranged on a semiconductor body (1). The transistor also has a drain zone (5) as well as a source zone (4) both formed in the semiconductor thin layer (3). The drain zone and the source zone are or a conductive type opposite to that of the first type. A gate electrode (11) is provided in or on the insulator layer (2). At least one field plate (8,9,10) is arranged between the gate electrode (11) and the drain zone (5). The distance between the field plate and the semiconductor thin layer increases with increasing distance from the gate electrode (11). Highly doped zones (7) of the second conductivity type in the thin layer (3) are connected to the field plate.
