Abstract

In its various embodiments, the method collects data from process and metrology tools in a semiconductor manufacturing environment, generates statistics from that data, detects tool failures, processing errors, and other conditions that can jeopardize product output, and performs high level process control in the form of tool shutdowns, lot holds, and lot releases. One method as disclosed automates the collection and recording of data from process and metrology tools, automates configuration of data collection, and automates process equipment shut downs, all within the existing framework of existing MES systems and engineering data collection systems. Automation of configurations and data collection is conducted by creation of data collection plans, data collection capability specifications, and other versioned documents within a process control and data collection system as disclosed herein. These versioned documents may be generated through a common graphical user interface and presented via an Internet web browser or other network interface.
