A resist pattern forming method using a coating and developing apparatus and an aligner being connected thereto which are controlled to form a resist film on a surface of a substrate with a base film and a base pattern formed thereon, followed by inspecting at least one of a plurality of measurement items selected from: reflection ratio and film thickness of the base film and the resist film, line width after a development, an accuracy that the base pattern matches with a resist pattern, a defect on the surface after the development, etc. A parameter subject to amendment is selected based on corresponding data of each measurement item, such as the film thickness of the resist and the line width after the development, and amendment of the parameter is performed. This results in a reduced workload of an operator, and the appropriate amendment can be performed.

Substrate processing method and apparatus

Resist pattern forming method

A resist pattern forming apparatus comprising a controller having a controlling portion that controls a processing of a coating and developing apparatus with a coating unit and a developing unit being provided therewith and an aligner being connected thereto, while an inspecting portion and the like measures at least one of a plurality of measurement items selected from, a reflection ratio and a film thickness of a base film and a resist film, a line width after the development, an accuracy that the base film matches with a resist pattern, a defect after the development, and so on. The measured data is transmitted to the controller. At the controller, a parameter subject to an amendment is selected based on the corresponding data of each of the measurement item such as the film thickness of the resist and the line width after the development, and the amendment of the parameters subject to the amendment is performed. As a result, the amending operation is facilitated by a reduced workload of an operator and in the same time, the appropriate amendment can be performed.

Processing apparatus and information storage apparatus and method

An object of the present invention is to grasp easily a process history of a target object such as a semiconductor wafer. The processing apparatus of the present invention includes: a processing apparatus body which includes a plurality of process units for executing a prescribed process to a target object, and transport mechanism for transporting said target object between the process units; a first controller for controlling the processing apparatus as a whole; a second controller for controlling the process units; an information storage section for taking in a signal transmitted and received between the first and second controllers; and a host computer for monitoring operation states of the process units. The present invention is extended to a processing system including a plurality of the processing apparatuses connected with a host computer which is further connected with a monitor computer through a communication network.

Substrate processing apparatus and information storage apparatus and method

A resist pattern forming method using a coating and developing apparatus and an aligner being connected thereto which are controlled to form a resist film on a surface of a substrate with a base film and a base pattern formed thereon, followed by inspecting at least one of a plurality of measurement items selected from: reflection ratio and film thickness of the base film and the resist film, line width after a development, an accuracy that the base pattern matches with a resist pattern, a defect on the surface after the development, etc. A parameter subject to amendment is selected based on corresponding data of each measurement item, such as the film thickness of the resist and the line width after the development, and amendment of the parameter is performed. This results in a reduced workload of an operator, and an appropriate amendment can be performed.

When a base film of a substrate is formed, for instance, on a scribe line of a wafer, a quadrangular first inspection pattern is formed in advance, and when a resist pattern is formed, a second inspection pattern are formed so as to be on a straight line to the first inspection pattern in a top plan view. When light is irradiated to a region including the first inspection pattern and the second inspection pattern and a spectrum is formed based on the reflected diffracted light, information of a line width of the second inspection pattern and a pitch of both inspection patterns is contained therein. In this connection, by preparing in advance a group of spectra based on various kinds of inspection patterns according to simulation and by comparing with an actual spectrum, the most approximate spectrum is selected, and thereby the line width and the pitch are estimated to evaluate the resist pattern.
