摘要:
During etching of a contact hole, not only the energy of ion irradiation but also the gas composition are altered to change the etching from a high-rate etching to a low-rate etching, thereby reducing the damage. In the low-rate etching where the gas composition is also altered, a firm fluorocarbon film is formed on the bottom of the contact hole, and the etching can be carried out while protecting the silicon surface. Consequently, inactivation of the impurities doped in the silicon surface can be prevented.

A dielectric film wherein N in the state of an Si3=≡N bonding is present in a concentration of 3 atomic % or more in the surface side of an oxide film and also is present in a concentration of 0.1 atomic % or less in the interface side of the oxide film can achieve the prevention of the B diffusion and also the prevention of the deterioration of the NBTI resistance in combination. When the Ar/N2 radical nitridation is used, it is difficult for the resultant oxide film to satisfy the condition wherein N in the above bonding state is present in a concentration of 3 atomic % or more in the surface side of an oxide film and simultaneously is present in a concentration of 0.1 atomic % or less in the interface side of the oxide film, whereas, the above distribution of the N concentration can be achieved by using any of the gas combinations of Xe/N2, Kr/N2, Ar/NH3, Xe/NH3, Kr/NH3, Ar/N2/H2, Xe/N2/H2 and Kr/N2/H2.

摘要:
A hydraulic control apparatus for a single action cylinder includes a switch valve for supplying fluid to and draining fluid from the cylinder, a cylinder side passage connected to the cylinder, a switch valve side passage connected to the switch valve, and a valve body accommodation chamber. The valve body accommodation chamber linearly extends between the cylinder side passage and the switch valve side passage. An on-off valve is located in a vicinity of a first end of the valve body accommodation chamber. The on-off valve defines a first back pressure chamber. A flow control valve is located in a vicinity of a second end that is opposite to the first end. The flow control valve defines a second back pressure chamber. The on-off valve and the flow control valve are separated from each other by a partitioning member.

A hydraulic parking brake device is selectively switched between a braking state and a non-braking state. A braking force decreases as a pressure in the control oil chamber increases and increases as the pressure in the control oil chamber decreases. The device includes a discharged oil restrictor located in a discharge passage and an accumulator connected to the control oil chamber. The accumulator is capable of releasing hydraulic oil to the control oil chamber when the braking force is greater than that at the time when the parking brake device is switched from the non-braking state to the braking state and the braking force can further be increased during the braking state of the parking brake device. Thus, the parking brake device can gradually brake the vehicle from the running state.

A microwave plasma processing apparatus is disclosed that enables fast and easy plasma ignition at the pressure for plasma processing In the microwave plasma processing apparatus, a plasma ignition facilitating unit is provided to facilitate plasma ignition induced by a microwave. The plasma ignition facilitating unit includes a deuterium lamp that emits vacuum ultraviolet rays, and a transmission window that allows the vacuum ultraviolet rays to penetrate and irradiate a plasma excitation space. The transmission window is a convex lens, and focuses the vacuum ultraviolet rays to enhance ionization of the plasma excitation gas. With such a configuration, it is possible to induce plasma ignition easily and quickly.

In a microwave plasma processing apparatus, the reflection of microwave by the joint unit between the microwave supplying waveguide and the microwave antenna is reduced by providing a taper surface or a member having a medium permittivity between the microwave supplying waveguide and the microwave antenna so as to moderate an impedance change. Accordingly, the efficiency of power supplying is improved, and reduced discharge ensures stable formation of plasma.
