摘要： Implementations disclosed describe a method of obtaining a first image of a sample using a first light, wherein the sample has been subjected to a processing operation associated with a change of a thickness of the sample. The method further includes weighing the sample to obtain a first mass of the sample. The method further includes determining, based at least in part on the first image of the sample and the first mass of the sample, one or more properties of the sample, such as the change of a thickness of the sample, a change of an refractive index of the sample, and/or a change of an optical density of the sample a distribution of the change of the thickness of the sample.

摘要： Methods for performing imaging reflectometry measurements include illuminating a measurement area on a sample using an input beam having a first peak wavelength, and obtaining multiple images of the measurement area using portions of the input beam reflected from the sample. A reflectance intensity value is determined for each of a plurality of pixels in each of the images. A parameter associated with the particular structure is determined using the reflectance intensity value.

摘要： An imaging reflectometer includes a source module configured to generate a plurality of input beams at different nominal wavelengths. An illumination pupil having a first numerical aperture (NA) is arranged so that each of the plurality of input beams passes through the illumination pupil. A large field lens is configured to receive at least a portion of each of the plurality of input beams and provide substantially telecentric illumination over a sample being imaged. The large field lens is also configured to receive reflected portions of the substantially telecentric illumination reflected from the sample. The reflected portions pass through an imaging pupil having a second NA that is lower than the first NA and are received by an imaging sensor module that generates image information.

摘要： Implementations disclosed describe a system that includes a deposition chamber, a light source to produce an incident beam of light, wherein the incident beam of light is to illuminate a region of the deposition chamber, and a camera to collect a scattered light originating from the illuminated region of the deposition chamber, wherein the scattered light is to be produced upon interaction of the first incident beam of light with particles inside the illuminated region of the deposition chamber. The described system may optionally have a processing device, coupled to the camera, to generate scattering data for a plurality of locations of the illuminated region, wherein the scattering data for each location comprises intensity of the scattered light originating from this location.

摘要： A system includes a radiation source configured to emit a radiation beam. The system further includes a first optical sensor configured to detect a first intensity of a first portion of the radiation beam reflected from a surface of an object. The system further includes a second optical sensor configured to detect a second intensity of a second portion of the radiation beam scattered by the surface of the object. The system further includes a processing device communicatively coupled to the first optical sensor and the second optical sensor. The processing device is configured to determine at least one of a roughness or an emissivity of the surface of the object based on a comparison of the first intensity and the second intensity.

摘要： Methods and systems for monitoring etch or deposition processes using image-based in-situ process monitoring techniques include illuminating a measurement area on a sample disposed in a process chamber. The measurement area is illuminated using an input beam generated remote from the process chamber and transmitted to a first viewing window of the process chamber by a first optical fiber. Portions of the first input beam reflected from the measurement area are transmitted from the first viewing window to an imaging sensor by a second optical fiber. A sequence of images is obtained at the imaging sensor, and a change in reflectance of pixels within each of the images is determined. The etch or deposition process is monitored based on the change in reflectance.

摘要： Implementations disclosed describe, among other things, a system and a method of scanning a substrate with a beam of light and detecting for each of a set of locations of the substrate, a respective one of a set of intensity values associated with a beam of light reflected from (or transmitted through) the substrate. The detected intensity values are used to determine a profile of a thickness of the substrate.
