Abstract: A gas treatment apparatus includes: a mounting part of a substrate; a gas diffusion plate of a processing gas; gas dispersion parts forming a diffusion space of the processing gas between the gas dispersion parts and the gas diffusion plate; and a flow path having an upstream side forming a common flow path of the gas dispersion parts and a downstream side connected to each of the gas dispersion parts, lengths from the common flow path to respective of the gas dispersion parts being aligned, wherein centers of the gas dispersion parts are located around a central portion of the diffusion space, and the gas dispersion parts are arranged along first circles with two or more of the gas dispersion parts arranged on each of the first circles and distances from the central portion of the diffusion space to the centers of gas dispersion parts being different from one another.

Abstract: A substrate transfer device includes a pick which has positioning pins to position a substrate and holds a positioned substrate; a drive unit which drives the pick such that the substrate is loaded/unloaded to/from a vacuum processing unit by using a pick; and a transfer control unit which controls a transfer operation of the substrate using the pick. The transfer control unit obtains in advance information on a reference position of the substrate at room temperature when the substrate is loaded into the vacuum processing unit, calculates a positional deviation from the reference position of the substrate when the substrate is loaded into the vacuum processing unit in actual processing, and controls a drive unit such that the substrate is loaded into the vacuum processing unit by correcting the positional deviation.
