摘要:
A substrate processing apparatus for performing a plasma process on a target substrate includes a process container configured to accommodate the target substrate. The apparatus includes a gas feed passage configured to supply a process gas into the process container and an exhaust passage configured to exhaust gas from inside the process container. The apparatus further includes a plasma generation mechanism configured to generate plasma of the process gas inside the process container and a metal component to be exposed to plasma inside the process container. The metal component is provided with a silicon film that coats at least a portion thereof to be exposed to plasma and to suffer an intense electric filed generated thereabout.

In a plasma oxidation processing apparatus (100) which supplies a high-frequency bias power to an electrode (7) embedded in a stage (5), the interior surface, which is to be exposed to a plasma, of an aluminum lid (27) which functions as an opposite electrode for the stage (5) is coated with a silicon film (48) as a protective film. Positioned adjacent to the silicon film (48), an upper liner (49a) and a thicker lower liner (49b) are provided on the interior surfaces of a second container (3) and a first container (2). This prevents a short circuit or abnormal electrical discharge to the interior surfaces, making it possible to form a proper high-frequency current path and enhance the efficiency of power consumption.

A processing apparatus includes an openable/closable lid disposed on a process container, and an opening/closing mechanism configured to open/close the lid. The opening/closing mechanism includes a hinge structure swingably coupling the lid to one end of the process container, and a drive structure configured to swing the lid. The hinge structure includes a main shaft used as a rotation axis when the lid is swung by the drive structure, and an adjusting shaft located on a distal end side relative to the main shaft, for adjusting an angle of the lid.

A substrate table includes a substrate table main body provided with a heater embedded therein and having an upper surface serving as a heating face for heating a target substrate, and lifter pins inserted in the substrate table main body and configured to be moved up and down. Recessed portions are formed in the heating face of the substrate table main body at positions corresponding to the lifter pins and have a bottom lower than the heating face. Each of the lifter pins includes a lifter pin main body and a head portion formed at a distal end of the lifter pin main body and having a diameter larger than the lifter pin main body, the head portion being formed to correspond to each recessed portion and to be partly accommodated in the recessed portion. The head portion has a head portion upper end for supporting the target substrate and a head portion lower surface opposite to the head portion upper end. The lifter pins are movable between a first state where the head portion lower surface engages with the bottom of the recessed portion, and a second state where the head portion lower surface separates upward from the bottom of the recessed portion.

A plunger pump, includes: a plunger pump unit including a pump chamber and a plunger for pressing a hydraulic fluid in the pump chamber to perform a discharging operation of the hydraulic fluid; a motor; and a cam portion driven by the motor to rotate and press the plunger. The cam portion has at least two discharge regions for pressing the plunger and a suction region formed between the discharge region. The plunger performs the discharging operation two times or more by one rotation of the cam portion.

Each pin fixing portion is fitted in a through-hole formed in a lifter arm, and includes a flange portion, a movable portion, a screw portion, and a pin insertion hole. A pin is fixedly screwed into the pin insertion hole at a lower end. The movable portion is inserted with an allowance in the through-hole, and the flange portion is set in contact with an upper surface of the lifter arm. The screw portion projects downward from the through-hole. A lower support portion is screwed on the screw portion and set in contact with a lower surface of the lifter arm.

A method permits the use of a low-cost bearing and by which a bearing unit can be manufactured without requiring lathe turning or any special kind of compression, pressure application, etc., that experiences low loss and which assures high precision in the perpendicularity of the rotating shaft to be supported by the bearing. The process for manufacturing a bearing unit in which bearing that supports a rotating shaft in a freely rotatable manner is secured to mounting member. The process includes at least the following three steps: the first step for providing sizing bar in hole in bearing into which the rotating shaft is to be inserted; the second step for working an end portion of the bearing, thereby forming in an end portion of the hole a small-diameter portion that is equal in size to the outside diameter of the sizing bar; and the third step for securing the bearing to the mounting member.
