H | ELECTRICITY |
01 | BASIC ELECTRIC ELEMENTS |
L | SEMICONDUCTOR DEVICES; ELECTRIC SOLID STATE DEVICES NOT OTHERWISE PROVIDED FOR |
29 | Semiconductor devices adapted for rectifying, amplifying, oscillating or switching, or capacitors or resistors with at least one potential-jump barrier or surface barrier, e.g. PN junction depletion layer or carrier concentration layer; Details of semiconductor bodies or of electrodes thereof; ; Multistep manufacturing processes therefor |
66 | Types of semiconductor device ; ; Multistep manufacturing processes therefor |
68 | controllable by only the electric current supplied, or only the electric potential applied, to an electrode which does not carry the current to be rectified, amplified or switched |
76 | Unipolar devices ; , e.g. field effect transistors |
772 | Field effect transistors |
78 | with field effect produced by an insulated gate |
786 | Thin film transistors, ; i.e. transistors with a channel being at least partly a thin film |
78696 | characterised by the structure of the channel, e.g. multichannel, transverse or longitudinal shape, length or width, doping structure, or the overlap or alignment between the channel and the gate, the source or the drain, or the contacting structure of the channel |
