  • Patent number: 11951562
    Abstract: A laser processing system is equipped with a processing laser beam irradiation device configured to irradiate a processing object with processing laser beam and perform ablation processing. The laser processing system is configured to obtain an ablation image of a processed portion of the processing object based on scattered light from the processed portion during processing of the processing object with the processing laser beam and to estimate an ablation volume by applying a learning result obtained by deep learning of a relationship between the ablation image and the ablation volume to the obtained ablation image.

  • Publication number: 20230145009
    Abstract: A configuration of the present disclosure specifies a signal point of a specific component and a background point, based on time series two-dimensional spectroscopic image data of a gas; calculates a correlation coefficient between a time series detection signal at the signal point and a time series detection signal at the background point; and generates a time series detection signal of the specific component, based on a corrected time series detection signal obtained by subtracting a product of the correlation coefficient and the time series detection signal at the background point from the time series detection signal at the signal point.

  • Patent number: 11350515
    Abstract: A laser system includes A. a laser apparatus configured to output pulsed laser light; B. a rare gas chamber; C. a light focusing optical system configured to focus the pulsed laser light in the rare gas chamber to excite the rare gas; D. a filter chamber configured to selectively transmit EUV light contained in harmonic light produced in the rare gas chamber; E. an exhauster connected to the filter chamber; F. at least one through hole disposed in the optical path between the rare gas chamber and the filter chamber; G. a rare gas supplier; H. a flow rate control valve configured to control the flow rate of the rare gas flowing from the rare gas supplier into the rare gas chamber; I. a first pressure sensor configured to detect the pressure of the rare gas in the rare gas chamber; J. a first controller configured to control the flow rate control valve in such a way that the pressure detected with the first pressure sensor falls within a reference range; and K.

  • Publication number: 20210299788
    Abstract: Deep learning is performed by using a material of a processing object, a laser beam parameter showing a property of laser beam which the processing object is irradiated with, and pre-processed part data and post-processed part data that respectively reflect laser processing-involved three-dimensional shapes of a processed part before and after irradiation of the processing object with the laser beam. A first relationship of input data that are the material of the processing object, the pre-processed part data, and the laser beam parameter to output data that is the post-processed part data after irradiation with the laser beam in relation to the input data is accordingly obtained as one learning result.
