IPC: H01L21/3065
Filed: 1994-07-11
Abstract: PURPOSE:To etch a SiO2 layer keeping high selectivity against a SixNy layer. CONSTITUTION:In a formation of self-matching contacts in an SRAM and in a selective dry etching of a SiO2 layer insulating film 39 on a SixNy etching stopping layer 38 that covers a gate electrode 35, a c-C4F8 gas at a just etching process and a c-C4F8/[(CH3)2N]4Si mixed gas at an over etching process are used. SixNy deposit generated in a gaseous state by decomposition of the [(CH3)2 N]4Si protects the exposed surface of the SixNy etching stopper layer 38 and improve the selectivity ratio. The deposit is removed by resolving in a hot phosphoric acid solvent after finishing the etching. With the etching of the SiOx layer with a SixNy mask in a similar gas, the dry 1 etching of high selectivity ratio is achieved.

Abstract: PURPOSE:To extend the range of an oscillation frequency under an given power supply voltage. CONSTITUTION:FET elements 6, 7 and 8 are parallel connected to an FET element 15 so that a current mirror circuit can be constituted. The respective FET elements of an FET element group 23 and FET elements 16 and 15 mutually consist of a current mirror circuit as well, and the respective FET elements of an FET element group 22 and an FET element 18 consist of the other current mirror circuit. A current I1 is changed corresponding to an input voltage signal VI, and a current I3 in proportion to the current I1 flows through the respective FET elements of the FET element groups 23 and 22. An oscillation frequency fOUT of a ring oscillator 21 is changed almost in proportion to the current I3. Since the current I1, is changed by selectively turning on/off the FET elements 6, 7 and 8 corresponding to control signals inputted to control terminals 3, 4 and 5, the oscillation frequency fOUT is changed over the much wider range. Thus, the range of the oscillation frequency is extended under the given power supply voltage.

Filed: 1996-06-20
Abstract: PROBLEM TO BE SOLVED: To execute communication by a high communication rate while keep ing occupation band width narrow. SOLUTION: SPU(signal processing unit) 62 of R/W(reader/writer) 41 BPSK (biphase shift keying) modulates data to be transmitted and, after that, outputs the modulating signal to a modulator/demodulator 63. The modulator/ demodulator 63 ASK-modulates the modulating signal and outputs it to a loop coil 64. The loop coil 64 generates a magnetic field corresponding to supplied modulation wave. An IC card 1 converts a part of the magnetic field radiated from RAW 41 into an electric signal by the loop coil 11, generates a power source from the electric signal and also extracts transmitted data. When data is transmitted to RAW 41, the load of the loop coil 11 is fluctuated in accordance with the data. Then, RAW 41 detects the load fluctuation of the loop coil in the IC card 1 which is magnetically connected by the loop coil 64.

Abstract: PURPOSE:To easily obtain a luminance signal and a color difference signal and to obtain a picture which has an extremely high resolving power especially in sensitivity by alternately giving one horizontal portion of dalay to an R signal and a B signal every one horizon in case of reading. CONSTITUTION:A switching switch 3, after a G' signal is read over the period of one horizon, is switched in order to read a G signal over the next period of one horizon and the read G' and G signals are recorded in the G channel of a magnetic disk 4. In the same way, by switching the switching switch 3, at first, one horizontal portion of the B signal is read and, next, one horizontal portion of the R signal is read, then the read B and R signals are recorded in the B/R channel of the magnetic disk 4. Since a G track and a B/R track are arranged in parallel, if these two tracks are simultaneously read by two magnetic heads the G and B signals or the G' and R signals are simultaneously obtained. Therefore, if the delay for the period of one horizon is given to the signal of the B/R channel, the G signal, the B signal and the R signal are simultaneously obtained.
