Method and apparatus for adaptively scheduling tool maintenance

Abstract

A method for adaptively scheduling tool maintenance includes controlling an operating recipe of a tool using a plurality of control actions, monitoring the control actions to identify a degraded tool condition, and automatically initiating a tool maintenance recommendation in response to identifying the degraded tool condition. A manufacturing system includes a tool, a process controller, and a tool health monitor. The tool is adapted to process a workpiece in accordance with an operating recipe. The process controller is adapted to control the operating recipe of the tool using a plurality of control actions. The tool health monitor is adapted to monitor the control actions to identify a degraded tool condition and automatically initiate a tool maintenance recommendation in response to identifying the degraded tool condition.
