Abstract (en)

[origin: DE19800647C1] The SOI (semiconductor-on-insulator) switch has a drift zone (11) of given conductivity within the drain zone (2,3) between a gate electrode (6) and a drain electrode (7,D) of the FET structure, with vertical troughs (8) formed in the drift zone and filled with semiconductor material (9,10) of opposite type. The vertical troughs may be filled with a polycrystalline silicon which is doped with a material of opposite conductivity type to the drift zone, with doping of the surrounding area by diffusion. The troughs may be provided in a grid structure.
