    摘要: A maintenance device has a cover and a fixing member. The cover is in a vacuum atmosphere during substrate processing, is formed to have a size corresponding to a boundary line between a first part and a second part of a processing container, which can be separated into the first part and the second part, or an opening surface separating the first part and the second part, and has airtightness, and visual transparency at least in a part. The fixing member fixes in an airtight manner the cover along the boundary line between the first part and the second part of the processing container or to the opening surface separating the first part and the second part.

    摘要: A mounting table includes a wafer mounting surface mounting a wafer, a ring mounting surface disposed at a radially outer side of the wafer mounting surface and mounting a first ring having a first engaging portion and a second ring having a second engaging portion to be engaged with the first engaging portion, a lifter pin, and a driving mechanism. The second ring has a through-hole extends to reach a bottom surface of the first engaging portion, and the ring mounting surface has a hole at a position corresponding to the through-hole. A lifter pin has a first holding part that fits into the through-hole and a second holding part that extends from the first holding part and has a part protruding from the first holding part. The lifter pin is accommodated in the hole, and a driving mechanism vertically moves the lifter pin.

    摘要: A plasma etching method according to an exemplary embodiment comprises arranging a substrate on an electrostatic chuck in a region surrounded by a focus ring. The substrate, in a state of being held by the electrostatic chuck, is etched by means of ions from a plasma. The electrostatic chuck includes a plurality of electrodes including a first electrode and a second electrode. The first electrode extends under a central region of the substrate. The second electrode extends under an edge region of the substrate. A plurality of voltages are respectively applied to the plurality of electrodes, wherein the plurality of voltages are determined such that, in the state in which the substrate is held by the electrostatic chuck, the ions from the plasma are incident on both the central region and the edge region substantially vertically.

    摘要: Disclosed is a method of inspecting a flow rate measuring system used in a substrate processing system. The flow rate measuring system provides a gas flow path used for calculating a flow rate in a build-up method. A gas output by a flow rate controller of a gas supply unit of the substrate processing system may be supplied to the gas flow path. In the method, apart from a previously obtained initial value of a volume of the gas flow path, a volume of the gas flow path is obtained at the time of inspection of the flow rate measuring system. Then, the obtained volume is compared to the initial value.
