Title: Method and equipment for fabricating semiconductor device
Inventor: SAITO YOSHIHARU
IPC: H01L21/31
Filed: 1993-11-22
Abstract: PURPOSE:To provide a method and equipment for fabricating a semiconductor device in which a silicon dioxide based insulating film can be embedded in a trench without generating any void; while eliminating the need for a high temperature glass flow step or an etch back step. CONSTITUTION:High density plasma is generated from oxygen gas at room temperature using helicon wave and a silicon dioxide based insulating film is grown on the surface of silicon by generating glow discharge between electrodes. Since a helicon wave plasma source is employed as an oxygen plasma source and the oxygen is ionized completely, a silicon diode based insulating film 6 is deposited on the exposed surface of a trench 5 made in a silicon substrate 1 but the resist is ashed on the surface thereof by the oxygen radicals and thereby no insulating film 6 is grown on the resist surface. Consequently, the silicon dioxide based insulating film can be grown selectively only on the exposed surface of silicon using resist.

Title: Semiconductor integrated circuit device and its signal supply method
Inventor: MORIMOTO MAHOMI
IPC: G06F1/10
Filed: 1998-11-06
Abstract: PROBLEM TO BE SOLVED: To control a clock signal regardless of the system constitution by switching the clock enable signals for every module under the condition of an input signal. SOLUTION: An input signal 14a is supplied to the FF(flip-flop) 19 and 25 respectively. When the change of the signal 14a is detected, a logical block 38 rises and supplies the changed signal 14a to the FF 10 and 39 respectively. The FF 10 fetches the signal 14a and outputs a signal 14b to an object module. The FF 39 supplies a clock enable signal CKE to a logical block 12 and validates a clock signal CLK1 to output it as a clock signal CLK2. The signals CLK2 are simultaneously supplied to the object module and a counter 17. The counter 17 counts the signal processing time of the object module and gives this counting result to a comparator 18. The comparator 18 compares the received signal processing time with the preset necessary signal processing time.  When the coincidence is confirmed between both signal processing times, the counter 17 ends its counting operation and at the same time the block 12 invalidates the signal CLK1.

Title: Overload preventive device for electric vehicle
Inventor: TAKEDA YASUSHI
IPC: H02P29/02
Filed: 1996-11-27
Abstract: PROBLEM TO BE SOLVED: To prevent overload in a motor driving circuit surely by adjusting the output of a motor driving circuit so that a difference between the maximum value and the minimum value of detected case temperature of respective switching elements may be a threshold value or lower. SOLUTION: An inverter main circuit 4 is constituted of switching element IGBTs T1 to T6 and diodes D1 to D6, and monitors the case temperature of power modules 5 to 7 of respective phases UVW during operation. The output of the inverter main circuit 4 is adjusted so that a difference between the maximum case temperature and the minimum case temperature in detected case temperatures of the respective phases UVW may be a threshold value or lower. In the threshold value, a value where the virtual junction temperature of IGBT indicating the maximum case temperature reaches an allowable value is obtained by calculation or experimental means for setting. As a result, the virtual junction temperature of the IGBT is adjusted to the maximum inverter output where it is allowable virtual junction temperature, thus it is possible to prevent overload in the IGBT with the maximum output maintained even at the time of motor locking.
