    摘要: A method for monitoring a processing tool in a semiconductor manufacturing facility includes selecting key hardware parameters for a virtual sensor system based on manufacturing data associated with a fabrication tool and collecting manufacturing data associated with the fabrication tool. The method further includes dynamically maintaining the virtual sensor system during the manufacture of a plurality of semiconductor products and using the virtual sensor system and the collected manufacturing data for predicting a condition of a semiconductor product after being processed by the fabrication tool.

    摘要: A semiconductor manufacturing information framework to operate a processing tool includes a data acquisition system (DAS), a virtual metrology (VM) system, a fault detection and classification (FDC) system and an advanced process control (APC) system. The DAS is operable to receive data related to the processing of a workpiece by the processing tool or sensors coupled on tool. The VM system is operable to receive the data from the DAS and predict results of the workpiece processed by the processing tool or sensors. The VM system generates at least one first output indicative of the results. The FDC system is operable to receive the data and generate at least one second output indicative of an operating status of the processing tool. The APC system is operable to receive the at least one first or second outputs, and, in response, generate at least one third output to control the processing tool.

    摘要: Uniform spatial distribution of plasma over the face of a semiconductor wafer is achieved using a multi-zone electrode forming part of an electrostatic chuck used to hold the wafer in a processing chamber. The electrode includes a plurality of concentric electrode portions to which differing RF bias voltages may be applied to produce an electric field having a desired spatial distribution. Sensors are used to monitor either the spatial distribution of the plasma or the process effects of the plasma, and the sensed information is fed back to a controller that adjusts the bias voltage on the electrode portions in a manner to maintain the spatial uniformity of the plasma.
