Abstract:
1. A system for fabricating a semiconductor device, comprising: a semiconductor fabrication tool having an integrated interface that measures a first process parameter of the fabrication tool, wherein the integrated interface is a wired I/O interface; a wireless sensor detachably coupled to the fabrication tool, wherein the sensor measures a second process parameter of the fabrication tool, the second process parameter being different from the first process parameter; and a diagnostic tool that is wirelessly coupled to the wireless sensor, wherein the diagnostic tool receives measured values of the first and second process parameters, wherein the diagnostic tool includes a centralized server that performs an analysis on the measured values of the first and second process parameters and generates a control signal in response to the analysis, the control signal instructing the semiconductor fabrication tool to adjust a fabrication operation, wherein the semiconductor fabrication tool includes a chemical mechanical polishing tool, and wherein the second process parameter includes a water resistance parameter.
