    摘要: A semiconductor device and a method for forming the same are disclosed. The semiconductor device comprising an insulated gate field effect transistor provided with a region having added thereto an element at least one selected from the group consisting of carbon, nitrogen, and oxygen, said region having established at either or both of the vicinity of the boundary between the drain and the semiconductor layer under the gate electrode and the vicinity of the boundary between the source and the semiconductor layer under the gate electrode for example by ion implantation using a mask. It is free from the problems of reverse leakage between the source and the drain, and of throw leakage which occurs even at a voltage below the threshold ascribed to the low voltage resistance between the source and the drain.

    摘要: It is intended to provide a semiconductor circuit including thin-film transistors (TFTs) having a small leak current and TFTs capable of operating at high speed, and a method for manufacturing such a circuit. A material containing a catalyst element is selectively formed so as to be in close contact with an amorphous silicon film, or a catalyst element is selectively introduced into an amorphous silicon film. The amorphous silicon film thus processed is crystallized by illumination with laser light or strong light equivalent to it. A crystalline silicon area with a small amount of catalyst element is used for TFTs in a pixel circuit and a crystalline silicon area with a large amount of catalyst element is used for TFTs in peripheral circuits of an active matrix circuit.

    摘要: In an active matrix display device, a circuit including at least five thin film transistors (TFTs) which are provided with an approximately M-shaped semiconductor region for a single pixel electrode and a gate line and a capacitances line which cross the M-shaped semiconductor region, is used as a switching element. Then, by supplying a selection signal to the gate line, the TFTs are operated, thereby writing data to the pixel, while if a suitable voltage is supplied to the capacitance line, a channel is formed thereunder and it becomes a capacitor. Thus the amount of discharge from the pixel electrode is reduced by this capacitor.
