An etching method and an etching system are adapted to produce a high etch selectivity for a mask, an excellent anisotropic profile and a large etching depth. An etching system according to the invention comprises a floating electrode arranged vis-à-vis a substrate electrode in a vacuum chamber and held in a floating state in terms of electric potential, a material arranged at the side of the floating electrode facing the substrate electrode to form an anti-etching film and a control unit for intermittently applying high frequency power to the floating electrode. An etching method according to the invention uses a material arranged at the side of the floating electrode opposite to the substrate electrode to form an anti-etching film as target and only rare gas as main gas and is adapted to repeat a step of forming a film on the substrate by sputtering by applying high frequency power to the floating electrode and a step of subsequently etching the substrate by suspending the application of high frequency power to the floating electrode and introducing etching gas into the vacuum chamber in a predetermined sequence.

摘要:
A method for manufacturing a semiconductor device comprises dry-etching a thin film using a resist mask carrying patterns in which at least one of the width of each pattern and the space between neighboring two patterns ranges from 32 to 130 nm using a halogenated carbon-containing compound gas with the halogen being at least two members selected from the group consisting of F, I and Br. The ratio of at least one of I and Br is not more than 26% of the total amount of the halogen atoms as expressed in terms of the atomic compositional ratio to transfer the patterns onto the thin film. Such etching of a thin film avoids causing damage to the resist mask used. The resulting thin film carrying the transferred patterns is used as a mask for subjecting the underlying material to dry-etching.

摘要:
A housing has an intake passage extending substantially in a vertical direction of a vehicle. A valve is configured to open and close the intake passage. A shaft supports the valve. A bearing supports the shaft. A hose is connected with an upper side of the housing in the vertical direction and configured to lead intake air into the intake passage. A communication passage configured to communicate an inside of an internal combustion engine of the vehicle with the hose. The communication passage has an opening in the vicinity of a point directly above the bearing. The hose has a wall surface defining a condensate passage, which connects the opening with a target location from which condensate is to be dropped.
