Title: Manufacture of semiconductor device
Inventor: SUGAWARA ATSUSHI
IPC: H01L21/3213
Filed: 1996-01-12
Abstract: PROBLEM TO BE SOLVED: To form a gate electrode constituted of a polysilicon film with high precision without complicating a process, by setting a ratio of HBr in etching gas composed of HBr and Cl2 to be smaller than or equal to a specified value in a just etching process, and setting it to be larger than or equal to the specified value in an over etching process. SOLUTION: A polysilicon film 4 is formed on a semiconductor substrate 1 via a gate oxide film 3. Mixture gas of HBr and Cl2 is used as etching gas, the ratio of HBr is set smaller than or equal to 55%, and the polysilicon film 4 is anisotropically etched as far as its film thickness. Over etching is performed by setting the ratio of HBr in the etching gas larger than or equal to 65%. For example, a photoresist film 5 is used as a mask, the ratio of HBr in etching gas 6 composed of HBr and C is set to be about 30%, and the polysilicon film 4 is just etched. Then the ratio of HBr in etching gas 7 is set to be 70%, and residue 4A of the polysilicon film 4 is over etched and eliminated.

IPC: H04J1/16
Filed: 1984-01-12
Abstract: PURPOSE:To always attain mutual monitoring of the reception state of monitor signals between both end offices by transmitting two types of monitor signals from both sides of a transmission line and controlling the monitor signal transmitted from own office at each of both end offices according to the reception state of the signal sent from the remote side office. CONSTITUTION:Two types of monitor signals S1 (104.08kHz) and S2 (84.08kHz) and a transmission signal S are transmitted to an end office B from an end office A via a transmission line 1 after hybrids 9a and 10a respectively. The office B demultiplex 11b and 12b these signals, delivers a reception signal R and detects 5b and 6b monitor signals S1 and S2. A logical circuit 7b transmits a control signal when the signal S1 is faulty and opens a switch 8b to stop the transmission of the signal S2. Both end offices A and B have exactly same constitution and therefore same actuation. For instance, a fault of at least a transmission line 2 is decided when detection is impossible for both signals S1 and S2 at the office A and the fault to a transmission line 1 when only signal S1 is detected. The signals S1 and S2 are detected when no fault is detected. Thus it is possible to always monitor the states of both offices with each other.

Title: Controller for reactive power compensator

IPC: G05F1/70
Filed: 1990-01-16
Abstract: PURPOSE:To obtain the optimum responsiveness by calculating the estimated value of a power impedance from a changed variable of the system voltage produced by the ON/OFF of a static capacitor and the capacity of a capacitor, and adjusting the control gain based on the estimated power impedance. CONSTITUTION:A power impedance estimating circuit 18 receives the ON/OFF switch signal and estimates a power impedance Z as Z = DELTAV/omegaCV from a changed variable DELTAV of the system voltage V and the capacity of a static capacitor C. A gain adjusting circuit 19 adjusts the gain Kp of a reactive power deciding circuit 15 in adverse proportion to the estimated impedance value Z. Thus the transient response of a control circuit 9 is delayed when the value Z is reduced. Thus the gain Kp of the circuit 15 is increased. On the contrary, the transient response of the circuit 9 is accelerated and the hunting is produced with increase of the value Z. Then the gain Kp of the circuit 15 is reduced for the stabilization of a series. In such constitution, the reactive power is controlled in a fast and stable way.
