Patent ID: 11881436
Assignee: APPLIED MATERIALS, INC.
Field: Measurement (Instruments)
Classification: CPC G  H | IPC G  H

Claim 8:
9. A substrate processing platform, comprising:
a factory interface for receiving a substrate;
a processing chamber connected to the factory interface for receiving the substrate for processing;
a system controller for controlling processing of the substrate; and
a metrology apparatus connected to one of the factory interface or the processing chamber for receiving the substrate and comprising:
an interferometer configured to obtain a first set of measurements at a first set of points along a surface of the substrate;
a sensor configured to obtain a second set of measurements at a second set of points different from the first set of points along the surface of the substrate;
an actuator configured to position the interferometer and the sensor at various positions along a measurement plane parallel to the surface of the substrate for obtaining the first set of measurements and the second set of measurements, wherein the actuator comprises an x-linear actuator that carries the interferometer and the sensor along an x-axis and a y-linear actuator that carries the interferometer and the sensor along a y-axis; and
a substrate support comprising a substrate support surface for supporting the substrate beneath the measurement plane while obtaining the first set of measurements and the second set of measurements.
