Patent number: 10596582Abstract: A deposition apparatus uniformly controlling deposited quantities of a plurality of depositing sources by efficiently determining an abnormal depositing source. The deposition apparatus may reduce loss of materials by exactly determining an abnormal depositing source. The deposition apparatus includes: a plurality of depositing sources spraying a deposition material; a substrate holder fixing a substrate to face the depositing source; a depositing source shutter disposed at one side of the depositing source and opening and closing an passage of each depositing source; and a main shutter disposed between the depositing source and the substrate fixed to the substrate holder and depositing a part of the deposition material on the substrate through the main shutter.Type: GrantFiled: July 17, 2017Date of Patent: March 24, 2020Assignee: Samsung Display Co., Ltd.Inventors: Sung-Joong Joo, You-Min Cha, Seuk-Hwan Park

Patent number: 10151022Abstract: A deposition apparatus includes deposition sources, a deposition chamber, a mask assembly, and a transfer unit. The mask assembly includes a support member, a shutter member, and a drive member. The support member has a first opening configured to allow the deposition materials to pass through while supporting the base substrate on which the passed-through deposition materials are deposited. The shutter member is accommodated in the support member and has a second opening smaller than the first opening. The drive member is configured to change a position of the second opening with respect to the base substrate in accordance with the movement of the mask assembly.Type: GrantFiled: October 2, 2017Date of Patent: December 11, 2018Assignee: Samsung Display Co., Ltd.Inventors: Min Ho Kim, You Min Cha, Seuk Hwan Park

Patent number: 8574367Abstract: In an evaporation source, a separable heater is used when an organic thin film is formed on a substrate in order to realize full-colors so that it is possible to correspond to crucibles of various capacities. The evaporation source comprises a crucible in which an organic material which is an organic thin film material is accommodated, and the crucible includes a heating unit and at least one spray nozzle for spraying the organic material onto a substrate. In the heating unit, a heater divided into at least two parts is provided on the external surface of the crucible at uniform intervals, and the heaters are separately disposed with respect to each other, but are connected to each other by connecting members. Therefore, it is not necessary to perform an additional design whenever the capacity of the crucible is changed, it is not necessary to exchange the evaporation source, and it is possible to reduce cost and to improve repairing ability.Type: GrantFiled: March 21, 2007Date of Patent: November 5, 2013Assignee: Samsung Display Co., Ltd.Inventors: Seuk Hwan Park, Kyung Hoon Chung, Yoon Sang Kwon, Kyong Tae Yu, Hyung Min Kim
