Patent number: 11167303Abstract: A repeatable manufacturing process uses a printer to deposits liquid for each product carried by a substrate to form respective thin films. The liquid is dried, cured or otherwise processed to form from the liquid a permanent layer of each respective product. To perform printing, each newly-introduced substrate is roughly mechanically aligned, with an optical system detecting sub-millimeter misalignment, and with software correcting for misalignment. Rendering of adjusted data is performed such that nozzles are variously assigned dependent on misalignment to deposit droplets in a regulated manner, to ensure precise deposition of liquid for each given area of the substrate. For example, applied to the manufacture of flat panel displays, software ensures that exactly the right amount of liquid is deposited for each “pixel” of the display, to minimize likelihood of visible discrepancies in the resultant display.Type: GrantFiled: March 18, 2019Date of Patent: November 9, 2021Assignee: Kateeva, Inc.Inventors: Michael Baker, Nahid Harjee, Douglas Bacon

Patent number: 8642136Abstract: A substrate processing method includes performing a deposition process of depositing a thin film on the substrate while depressurizing the inside of the processing chamber and introducing the gas thereinto; and, while the deposition process is being performed, irradiating light, which is transmitted through a monitoring window installed at the processing chamber, toward the inside of the processing chamber through the monitoring window, and monitoring a reflection light intensity of reflection light by receiving the reflection light through the monitoring window. The substrate processing method further includes measuring a temporal variation in the reflection light intensity during the deposition process and calculating a termination time of the deposition process based on a measurement value of the temporal variation; and terminating the deposition process by setting the termination time as an end point of the deposition process.Type: GrantFiled: October 7, 2009Date of Patent: February 4, 2014Assignee: Tokyo Electron LimitedInventors: Masato Kushibiki, Eiichi Nishimura, Akitaka Shimizu

Patent number: 8609442Abstract: A coating film (90) is formed by causing vapor deposition particles (91) discharged from a vapor deposition source opening (61) of a vapor deposition source (60) to pass through a space between a plurality of control plates (81) of a control plate unit (80) and a mask opening (71) of a vapor deposition mask in this order and adhere to a substrate, while the substrate (10) is moved relative to the vapor deposition mask (70) in a state in which the substrate (10) and the vapor deposition mask (70) are spaced apart at a fixed interval. A difference in the amount of thermal expansion between the vapor deposition source and the control plate unit is detected and corrected. It is thereby possible to form, at a desired position on a large-sized substrate, the coating film in which edge blur and variations in the edge blur are suppressed.Type: GrantFiled: October 11, 2011Date of Patent: December 17, 2013Assignee: Sharp Kabushiki KaishaInventors: Satoshi Inoue, Shinichi Kawato, Tohru Sonoda
