Publication number: 20250116004Abstract: Provided is a substrate processing apparatus. The positions of a first electrode and a second electrode are adjusted in advance in consideration of differences in coefficients of thermal expansion so that a short circuit created by contact between the first electrode and the second electrode is prevented even in the case in which the first electrode and the second electrode are thermally expanded during processing. Even in the case in which the first electrode and the second electrode are thermally expanded due to an increase in temperature during processing, a short circuit between the first electrode and the second electrode can be prevented, and the uniformity of a thin film can be maintained in the substrate processing apparatus for processing a large substrate.Type: ApplicationFiled: December 17, 2024Publication date: April 10, 2025Inventors: Jae Wan LEE, Yong Hyun KIM, Yoon Jeong KIM, Yun Hoe KIM, Chang Kyun PARK, Gu Hyun JUNG, Ki Bum KIM, Seung Youb SA, Chul Joo HWANG

Patent number: 10741141Abstract: A method of arranging components in an integrated circuit includes providing two or more circuit cells of a first type and providing two or more circuit cells of a second type. The circuit cells of the first type are configured to operate in conjunction with the circuit cells of the second type. The method further includes arranging the circuit cells of the first and second types in an alternating pattern such that each circuit cell of the first type is adjacent to at least one circuit cell of the second type. The alternating pattern may be an array of rows and columns and may include a repeating pattern of one first type cell and one second type cell in each of the columns. The alternating pattern may include a repeating pattern of one cell of the first type and two cells of the second type in each of the columns.Type: GrantFiled: February 6, 2015Date of Patent: August 11, 2020Assignee: Kopin CorporationInventors: Yong Seok Seo, Jin Kuk Kim, Seung Youb Kim

Patent number: 10636347Abstract: A method of driving a pixel array includes providing a ramp signal to one or more columns of the pixel array. For each cycle of the ramp signal, the method further includes providing a first row driving signal to at least a first row of the pixel array and a second row driving signal to a second row of the pixel array. A pixel array driver may include a ramp signal generator configured to produce a ramp signal, a first amplifier configured to receive the ramp signal and produce a first amplified ramp signal, and a second amplifier configured to receive the ramp signal and produce a second amplified ramp signal. The first amplified ramp signal may be electrically connected to a first set of pixels of a pixel array, and the second amplified ramp signal may be electrically connected to a second set of pixels of the pixel array.Type: GrantFiled: April 12, 2019Date of Patent: April 28, 2020Assignee: Kopin CorporationInventors: Jin Kuk Kim, Yong Seok Seo, Seung Youb Kim, Jang Ho Kim, Frederick Herrmann
