Abstract: Methods and apparatus that monitors deposition on a shutter disk in-situ. In some embodiments that apparatus may include a process chamber with an internal processing volume, an enclosure disposed external to the internal processing volume where the enclosure accepts a shutter disk when the shutter disk is not in use in the internal processing volume, a shutter disk arm that moves the shutter disk back and forth from the enclosure to the internal processing volume, and at least one sensor integrated into the enclosure. The at least one sensor is configured to determine at least one film property of a material deposited on the shutter disk after a pasting process in the internal processing volume.

Abstract: Methods and apparatus perform backside via reveal processes using a centralized control framework for multiple process tools. In some embodiments, a method for performing a backside via reveal process may include receiving process tool operational parameters from process tools involved in the backside via reveal process by a central controller, receiving sensor metrology data from at least one or more of the process tools involved in the backside via reveal process, and altering the backside reveal process based, at least in part, on the process tool operational parameters and the sensor metrology data by adjusting two or more of the process tools involved in the backside via reveal process. The profile parameters are configured to prevent backside via breakage during a chemical mechanical polishing (CMP) process.
