Title: Manufacture of semiconductor device
Inventor: YUKI TOMOHIRO
IPC: H01L21/8238
Filed: 1994-11-18
Abstract: PURPOSE: To form a junction provided with favorable electrical characteristics excellently in controllability. CONSTITUTION: At the time of formation of junction, the substrate is made amorphous from the surface to a fixed depth D1 by implanting ions not contributive to the conductivity into a crystal region. Next, impurity ions to give opposite conductivity to the conductivity in that crystal region are implanted to form effective impurity distribution of D3 in depth deeper than D1, on condition of forming an amorphous layer of D2 shallower than the said D1 in case that the ions are implanted singly into that crystal region. Then, annealing is performed to recrystallize the amorphous layer and activate the impurities.

Title: Arrester directly attached on main line
Inventor: KAMIYA YOSHISHIGE
IPC: H01T1/14
Filed: 1993-10-21
Abstract: PURPOSE:To prevent tracking current by electrically connecting conductive members together that are provided on the power supply side and the grounding side of a display window. CONSTITUTION:When an arrester element 10 is in a sound state, if the voltage to ground of a distribution line 1 is applied thereto, earth current does not flow due to the high resistance of the distribution line, and when a lighting impulse is applied, the lighting impulse is discharged by the element 10 by means of a varistor characteristic to absorb lighting surge voltage. Since the steepness of the lighting impulse current is large, the impedance of solenoids 16A and 16B becomes large. As a result, the small gaps provided in parallel to the solenoids 16A, 16B discharge, and the discharged current flows into the ground through a plunger 17, an electrode rod 18, an earth fitting 24, and a grounding lead 9. When the element 10 is degraded and the insulation resistance is lowered, leak earth current flows at the voltage to ground of the line 1, and current flows in the solenoids 16A, 16B, while the hooked hole 18A of the electrode rod 18 is removed by means of excitation, and the rod falls down to cut off the earth current. Tracking current can thus be prevented from flowing in a display window 8.

IPC: H03K17/687
Filed: 1996-10-09
Abstract: PROBLEM TO BE SOLVED: To reduce gate drive loss at the time of light load and conduction loss at the time of normal load, by a dual gate 2 power MOSFET having a plurality of gates which have different gate widths and electrically isolated. SOLUTION: An MOS FET M contains a source S and a drain D, and has gates G1 and G2 which are electrically isolated. The state of the MOSFET M is controlled by the gates G1 and G2. The gate width of the gate G1 is W1, and the gate width of the gate G2 is W2 where W2 is N times W1. In the normal operation mode, ON/OFF switching of the gates G1 and G2 is performed by a pulse width modulation signal. When the magnification factor N is large, a channel controlled by the gate G2 carries a greater part of current, and the ON resistance of the MOSFET M becomes low. In the state of light load, the gate G1 is subjected to switching, but the gate G2 is grounded, so that consumption of unnecessary energy can be avoided.
