An information acquisition system configured to acquire information upon a substrate processing apparatus configured to process a substrate held by a substrate holder includes a base body, instead of the substrate, held by the substrate holder; and multiple position sensors provided at the base body such that detection directions thereof are different from each other, and each configured to detect a position of a common detection target object located outside the base body.

Information acquisition system and information acquisition method

A state determination device determines the state of a drive mechanism configured to operate while holding a substrate in a substrate processing apparatus. The state determination part includes: an acquisition part configured to acquire operation data for the drive mechanism; a model generation part configured to generate a monitoring model for the drive mechanism by executing machine learning using an auto-encoder based on normal operation data that is derived from the operation data acquired by the acquisition part when the drive mechanism is operating normally; and a first determination part configured to determine the state of the drive mechanism based on first output data obtained by inputting, to the monitoring model, evaluation data that is derived from the operation data acquired by the acquisition part when the drive mechanism is being evaluated.

State determination device, state determination method, and computer-readable recording medium

A substrate processing apparatus configured to process a substrate includes a functional component constituting a part of the substrate processing apparatus; a nozzle, provided on a surface of the functional component, allowing a gas to pass therethrough; a nozzle flow path which is connected to the nozzle of the functional component and through which the gas flows; a flow rate sensor configured to measure a flow rate of the gas flowing through the nozzle flow path; and a controller configured to make a determination upon a state of a distance between an interfering object and the functional component based on a measurement result obtained by the flow rate sensor.

A heat treatment apparatus of heating a substrate mounted on a mounting plate heated by a heating part includes: plural types of physical quantity detecting parts for detecting plural types of physical quantities, respectively; a state estimating part for estimating an occurrence probability occurring for each of abnormality modes by a neural network, and including an input layer to which a group of time-series detection values obtained for each of physical quantity detection values detected respectively by the physical quantity detecting parts is inputted; and a selecting part for selecting one of correspondence processes based on the occurrence probability of each of the abnormality modes estimated by the state estimating part. One of the physical quantity detection values is a temperature detection value detected by a temperature physical quantity detecting part for detecting a temperature of the mounting plate among the physical quantity detecting parts.

Heat treatment apparatus, method of managing heat treatment apparatus and storage medium

Disclosed is an inspection device for inspecting deformation of a substrate holding member of a substrate transport apparatus. The substrate holding member is moved in the forward-and-backward direction relative to the transport base to pass across a light path of the detection light formed by an optical detection unit. The position, with respect to a direction transverse to the forward-and-backward direction, of the substrate holding member is detected based on a detection signal of the optical detection unit. Based on a correlation data expressing the relationship between a first parameter indicative of a change of a position of the substrate holding member with respect to the forward-and-backward direction and a second parameter indicative of the change of the position of the substrate holding member with respect to the direction transverse to the forward-and-backward direction, whether or not deformation occurs in the substrate holding member is judged.
