Filed: 1991-08-28
Abstract: PURPOSE:To prevent too high temperature over the heat resistance limit of a photoresist itself due to heat produced by the peaction heat with the etching species by previously determining a suitable range of combinations of the etching rate and the pressure of the etching atmosphere and etching it in a down--flow type of plasma etching. CONSTITUTION:CF4+O2 mixture gas is used as reaction gas 3, and a wafer 11 is etched with photoresist as a mask material. It is necessary to prevent a too high temperature over the heat resistance limit of the photoresist itself even if a temperature rises due to heat generated by the reaction with etching species. Thus, the range of combinations of the etching rate of the photoresist and the pressure of the etching atmosphere are previously determined. In the combination range, the rate is under 310mm/min the pressure is over 0.29Pa. The rate is obtained by optically measuring the thickness of the resist before and after the etching, and dividing it by the etching time. The pressure is measured by a Pirani vacuum gauge 13.

Filed: 1987-09-29
Abstract: PURPOSE:To automatically switch a fountain control circuit by previously recording an auxiliary signal to be used as the discriminating signal in a compact cassette tape for fountain control, and identifying the tape for fountain control from the reproduced contents. CONSTITUTION:The music signals A and B of a magnetic tape 1 and a fountain- control auxiliary signal group C are reproduced by a magnetic tape reproducing device 2. Meanwhile, the null for more than a specified time is detected by the stop detecting circuit 7.

Filed: 1987-09-28
Abstract: PURPOSE:To correctly read a new clock run signal and an index signal by providing a carrier signal sector longer than the sum of an index sector and a clock run signal sector to the start of the index sector of a magnetic track. CONSTITUTION:A carrier signal sector 155 is formed by 3H from the tip of recording pulse of a 6H recording pulse, then a clock run signal SCL is formed by 2H and then an index signal CDIX is recorded over 1H respectively.
