Abstract:
1. A Field Effect Transistor (FET) device, comprising: a source electrode and a drain electrode; a device body located in-between said source electrode and said drain electrode, having a source interface with said source electrode and having a drain interface with said drain electrode, wherein said body comprises a concentration of impurities of a first type, wherein said concentration next to said source interface is higher than said concentration next to said drain interface, wherein said first type of impurities are capable to give rise to charge carriers of a first type; a device channel hosted by said device body, wherein said channel is capable of carrying a device current between said source electrode and said drain electrode, wherein said device current consists essentially of charge carriers of a second type; wherein said FET device is free of any structure providing for electrical contact between said source electrode and said device body; and wherein said FET device is characterized as being a silicon-on-insulator (SOI) FET, and said body is characterized as being a floating body.
