摘要:
A thin-film semiconductor device or integrated circuit comprising an insulating substrate, TFTs (thin-film transistors) formed on the substrate, and multilayer conductive interconnections. The circuit has a first metallization layer becoming gate electrodes and gate interconnections. The surface of the first metallization layer is oxidized by anodic oxidation to form an insulating coating on the surface of the first metallization layer. A second metallization layer becoming source and drain electrodes or conductive interconnections is then formed on the insulating coating directly or via an interlayer insulator. An improvement in the production yield and improved reliability are accomplished.
摘要:
An insulated-gate field-effect transistor adapted to be used in an active-matrix liquid-crystal display. The channel length, or the distance between the source region and the drain region, is made larger than the length of the gate electrode taken in the longitudinal direction of the channel. Offset regions are formed in the channel region on the sides of the source and drain regions. No or very weak electric field is applied to these offset regions from the gate electrode.
摘要:
A semiconductor device or a semiconductor integrated circuit includes a field effect transistor having a source region, a drain region and a channel regions formed within a semiconductor substrate. A lower wiring is formed on the semiconductor substrate to form a gate electrode and its extension and oxidized to form an oxide film covering the lower wiring. An upper wiring is formed over the lower wiring on the semiconductor substrate to make contact with the drain or source region. The lower wiring is electrically insulated from the upper wiring by the oxide film.

摘要:
A multilayer semiconductor integrated circuit which does not suffer from latchup. The circuit comprises a semiconductor substrate, a first MOS transistor formed on the substrate, an interlayer insulator deposited on the first transistor, and a second MOS transistor formed on the interlayer insulator. The two transistors have different conductivity types. The gate electrode of the second transistor consists mainly of metal or metal silicide, e.g. aluminum. The upper and side surfaces of the gate electrode is coated with a material comprising an oxide of the metal or metal silicide.

摘要:
A wiring formed on a substrate is oxidized and the oxide is used as a mask for forming source and drain impurity regions of a transistor, or as a material for insulating wirings from each other, or as a dielectric of a capacitor. Thickness of the oxide is determined depending on purpose of the oxide. In a transistor adapted to be used in an active-matrix liquid-crystal display, the channel length, or the distance between the source region and the drain region, is made larger than the length of the gate electrode taken in the longitudinal direction of the channel. Offset regions are formed in the channel region on the sides of the source and drain regions. No or very weak electric field is applied to these offset regions from the gate electrode.
