Title: Manufacture of semiconductor device and semiconductor manufacturing device
Inventor: HORI MASARU
IPC: C23F4/00
Filed: 1992-01-13
Abstract: PURPOSE:To remove an organic film pattern by dry-etching step rapidly and surely at a high selection ratio to a carbon film by a method wherein the etching gas containing an active species containing halogen atoms and another active species containing oxygen atoms is used. CONSTITUTION:When oxygen gas only is used as an etching gas, both a resist and a carbon film are not etched away but the etching rate of the resist can be accelerated by mixing a bit of CF4 gas with the oxygen gas. Accordingly, when the flow rates of CF4 and O2 are respectively specified to be 20 SCCM and 480 SCCM, the etching rates of the resist and the carbon film are respectively to be 1000 Angstrom /min and 16Angstrom /min thereby enabling the title manufacture to have the high selection ratio of 600. Through these procedures, the resist film can rapidly be removed at a high selection ratio to the carbon film.

Filed: 1982-01-15
Abstract: PURPOSE:To receive a desired signal only for sharp communication, without interference, by controlling a transmission circuit and a reception circuit so that the reception is stopped at the transmission and the oscillation is stopped at the reception with an output of an oscillation circuit and receiving the transmission output of itself and spurious component. CONSTITUTION:When an output of an oscillation circuit 5a is ''H'', i.e., the control input of a transmission circuit 1a is ''H'', then the circuit 1a makes transmission, and when the control input of a reception circuit 3a is ''H'', a reception circuit 8a stops reception, and when both the control inputs are ''L'', the circuit 1a stops the transmission and the circuit 3a makes reception. 5b is oscillated with the same frequency fb (fanot equal to fb) as the frequency of the oscillation circuit 5a of the device B and controls a transmission circuit 1b and a reception circuit 3b similarly. Thus, since the reception of the circuit 3a is stopped when the transmission circuit 1a makes transmission, the transmission output of itself and its spurious component are not received and since the transmission output of the circuit 1a is stopped when the circuit 3a makes reception, the effect of the transmission output of the circuit 3a is not effected.
