Filed: 1994-09-28
Abstract: PURPOSE: To provide a semiconductor device which reduces off-current of a TFT and has stable characteristics by maintaining an offset region of a P-type TFT while realizing high integration. CONSTITUTION: A first insulation film 102 is formed on a semiconductor substrate 101 and a gate electrode 103 consisting of a first conductive film is formed thereon. In the process, a dummy pattern 104 of the same layer as the gate electrode 103 is formed below an offset between channel-drain 109.

This thin film transistor(TFT) constitution is especially effective for a memory cell of an SRAM which requires high integration, low standby current and good data retention characteristic.

Filed: 1984-11-06
Abstract: PURPOSE:To improve the yield of a feeding circuit and the economy of a subscriber circuit by adding a constant electric current source to any of two sets of feeding circuits so as to adjust the off-current. CONSTITUTION:When a subscriber current i3 exceeds a prescribed constant current because an off-current io1 outputted from a feeding circuit 1 is less than an off-current io2 outputted from a feeding circuit 2, a high resistance 4 is connected to the terminal C of an amplifier circuit 11. As a result, a source current icl' inputted to the amplifier circuit 11 is increased and the off-current io1 is increased also. Since the off-current io2 outputted from the feeding circuit 2 is less than the off-current io1 outputted from the feeding circuit 1, if the subscriber current i3 exceeds a prescribed current, the high resistance 4 is connected to the terminal C of an amplifier circuit 21. As a result, a source current ic2' inputted to the amplifier circuit 21 is increased and the off-current io2 is also increased. In deciding properly the resistance value of the high resistor 4, the subscriber current 13 is adjusted within a prescribed current.

Title: Electrically conductive resin composition and preparation thereof
Inventor: YAMAUCHI SATORU
IPC: C08L101/00
Filed: 1999-08-20
Abstract: PROBLEM TO BE SOLVED: To stably provide an electrically conductive resin composition having an electrical conductivity of 1.0×10-4 Ω.cm or smaller. SOLUTION: This electrically conductive resin composition comprises a thermoplastic resin 1, a metal powder or metal fiber 3 and a low-melting metal 2, wherein the melt flow rate(MFR) of the thermoplastic resin 1 is from 2 to 25 g/10 min. This allows the low-melting metal 2 and the metal powder 3 to be regularly dispersed in the resin composition without agglomerating and allows the metals to be interconnected, therefore inhibiting the agglomeration of the low-melting metal 2 at the surface of the resin composition. As a consequence, an electrically conductive resin composition having a volume specific resistivity of 1.0×10-4 Ω.cm or smaller wherein the metal powders 3 are uniformly dispersed and interconnected, is stably obtained. The melting point of the low-melting metal 2 may be identical to or higher than that of the above thermoplastic resin 1.
