Title: Manufacture of semiconductor device
Inventor: OKAMOTO AKIHIKO
IPC: H01L29/778
Filed: 1985-10-11
Abstract: PURPOSE:To elevate the barrier of a gate electrode part by a method wherein a thin film of impurity or material containing the impurity which provides a conductivity type different from that of the 1st semiconductor layer is formed on the 1st semiconductor layer by performing evaporation, and a gate electrode is formed followed by a heat treatment. CONSTITUTION:A nondoped gallium arsenite layer 2, a nondoped gallium- aluminum arsenite layer 3, an N-type gallium-aluminum arsenite layer 4 and an N-type gallium arsenite layer 5 are successively formed on a semi-insulating gallium arsenite substrate 1 by a vapor phase deposition method and a film 6 of beryllium, which is P-type impurity, is evaporated. Then aluminum, which is metal for a gate electrode, is evaporatted and etched to form the gate electrode 7 and further ohmic metal layers 8 and 9 are evaporated. If this semiconductor device is subjected to a heat treatment at 350-450 deg.C, the beryllium is thermally diffused and a P-type conductive layer 6' is formed and, at the smae time, excellent ohmic contacts 8' and 9' are formed. Therefore, the height of the barrier of the gate electrode part can be made to be higher than the surface potential between the source and the gate. With this constitution, even in a normally-OFF type FET, increase of source resistance can be suppressed.

The bone 20 may be rotated to a natural orientation state under the tension of the connecting ligaments by the supporting. On the other hand, the template supported by a jack assembly 45 is disposed to face the regulated resection end 21 and, therefore, the cutting to be executed afterward exists at adequate rotational alignment. The bone is subjected to the natural orientation position when a joint component element is mounted.

Title: Photoelectric conversion device and drive thereof
Inventor: ASABA TETSURO
IPC: H01L21/331
Filed: 1987-09-11
Abstract: PURPOSE:To provide high-power output by connecting one principal electrode of a first transistor to a control electrode region of a second transistor and also connecting another principal electrode of the first transistor to a principal electrode of the second transistor. CONSTITUTION:When a low voltage is applied to a capacitor electrode 26, the potential of a base region B2 declines to come to a state of forward bias for an emitter region E2 and a hole current flows between emitter and collector regions. As the base region B2 is in a state of floating, accumulated electrons initiate disappearing by their recombination and accordingly, potential changes into a positive direction. During the period of these processes, the hole current flows from the emitter region E2 to the collector region C2 and to flow in the vase region B1 through an electrode 28. As a result, hole currents which are obtained as the sum of an electric charge accumulated at the base region B1 and the product of the electric charge accumulated at the base region B2 and current gain are accumulated by these operations, when accumulating action are performed.

Title: Electronic equipment
Inventor: NAKADA SHINICHI
IPC: G06F1/00
Filed: 1984-10-30
Abstract: PURPOSE:To attain high-speed processing when there is no problem on the consumption of an internal battery by adopting a high clock frequency when it is detected that power is supplied externally. CONSTITUTION:When no external power is supplied, a voltage detector C outputs '0'. Since an oscillator CG is oscillated at a low frequency when '0' is inputted, the processing speed of an arithmetic circuit ALC is slow, but the power consumption is small and the wear of a battery B is less. When a power supply is connected to an external terminal EX, the voltage Vc is large, it is detected by the voltage detector C, which outputs '1'. In this case, the oscilla tor CG is oscillated in a high frequency and sincea high frequency clock is applied to the arithmetic circuit ALC, the processing speed is faster.
