Integrated metrology tools for monitoring and controlling large area substrate processing chambers
Embodiments of an apparatus and method of monitoring and controlling a large area substrate processing chamber are provided. Multiple types of metrology tools can be installed in the substrate processing system to measure film properties after substrate processing in a processing chamber. Several number of a particular type of metrology tools can also be installed in the substrate processing system to measure film properties after substrate processing in a processing chamber. The metrology tools can be installed in a metrology chamber, a process chamber, a transfer chamber, or a loadlock.
1. A metrology chamber of a substrate processing module adapted to monitor and/or control at least one substrate processing chamber of the substrate processing module, comprising:
at least one first metrology tool disposed in the metrology chamber, wherein the at least one first metrology tool is a film thickness measurement tool; and
at least one second metrology tool. physically separate and distinct from the at least one first metrology tool, disposed in the same metrology chamber, wherein there are at least two film thickness measurement tools and one of the film thickness measurement tools is placed to measure film thickness near the center of a substrate that has been processed in one of the at least one substrate processing chamber and the other film thickness measurement tool is placed to measure film thickness away from the center of the substrate.
2. A large area substrate processing system comprising:
a plurality of substrate processing chambers coupled to a transfer chamber; and
a metrology chamber coupled to a transfer chamber, the metrology chamber comprising:
at least a first metrology tool disposed in the metrology chamber, wherein the first metrology tool is a film thickness measurement tool; and
at least a second metrology tool disposed in the same metrology chamber, wherein there are at least two film thickness measurement tools and the first film thickness measurement tool is placed to measure film thickness near the center of a substrate that has been processed in one of the plurality of substrate processing chambers and the second film thickness measurement tool is placed to measure film thickness away from the center of the substrate.
