Patent number: 11898249Abstract: A method of processing a substrate according to a PECVD process is described. Temperature profile of the substrate is adjusted to change deposition rate profile across the substrate. Plasma density profile is adjusted to change deposition rate profile across the substrate. Chamber surfaces exposed to the plasma are heated to improve plasma density uniformity and reduce formation of low quality deposits on chamber surfaces. In situ metrology may be used to monitor progress of a deposition process and trigger control actions involving substrate temperature profile, plasma density profile, pressure, temperature, and flow of reactants.Type: GrantFiled: February 13, 2023Date of Patent: February 13, 2024Assignee: Applied Materials, Inc.Inventors: Nagarajan Rajagopalan, Xinhai Han, Michael Wenyoung Tsiang, Masaki Ogata, Zhijun Jiang, Juan Carlos Rocha-Alvarez, Thomas Nowak, Jianhua Zhou, Ramprakash Sankarakrishnan, Amit Kumar Bansal, Jeongmin Lee, Todd Egan, Edward W.

Patent number: 9335151Abstract: In one embodiment, a sample is tested by an eddy current sensor at two distances separated by a known incremental distance. In one aspect, at least one of an unknown distance of the sensor from the test sample and the film thickness of the test sample may be determined as a function of a comparison of sensor output levels of a single parameter and the known incremental distance to calibration data. In yet another aspect, the distance between the sensor and the test sample may oscillated to produce an oscillating sensor output signal having an amplitude and mean which may be measured and compared to calibration data to identify at least one of the unknown film thickness of a conductive film on a test sample, and the unknown distance of the test sample from the sensor.
