Patent number: 7097750Abstract: A device to fix a substrate for a thin film sputter, includes a mask, a mask pressing plate, a magnetic body, and a driving unit. The mask having patterns is positioned under the substrate so as to form the patterns on the substrate. The mask pressing plate is positioned over the substrate and moves toward and contacts a back surface of the substrate at a predetermined pressure. The magnetic body is placed over the mask pressing plate and moves toward the mask pressing plate so as to have the mask adhere closely to the substrate by a magnetic force of the magnetic body. The driving unit applies a driving force to move the magnetic body. Where the mask pressing plate descends, the mask pressing plate adheres closely to the substrate. Thereafter, the magnetic body descends toward the back surface of the substrate which is supported by the mask pressing plate. The mask underneath the substrate adheres closely to a front surface of the substrate by the magnetic force of the magnetic body.Type: GrantFiled: May 30, 2003Date of Patent: August 29, 2006Assignee: Samsung SDI Co., Ltd.Inventors: Chang Ho Kang, Yong Weon Jang, Tae Seung Kim

Publication number: 20060012280Abstract: A deposition mask and a method for manufacturing an organic light emitting display (OLED) using the same are provided. The deposition mask is intended for preventing an organic film from being damaged due to touching of a blocked-off portion of the mask to an emission layer (EML), or chemical transition from being generated at the organic film. For that purpose, the deposition mask stuck to a substrate of the OLED to deposit an organic EML includes an opening and an indentation. The opening is opened so as to deposit the organic EML. The indentation is indented a predetermined depth from a plane facing the substrate.Type: ApplicationFiled: July 14, 2005Publication date: January 19, 2006Inventors: Chang-Ho Kang, Tae-Seung Kim, Jae-Min Hong

Patent number: 6955726Abstract: A mask frame assembly includes a frame having an opening and a mask having at least two unit mask elements. Both ends of each unit mask element are fixed to the frame in a state of tension. The unit mask elements include a unit masking pattern, and overlap each other on a predetermined width to form a single mask pattern block. Each unit mask element has a recessed wall in an overlapping portion thereof so as to maintain the thickness of the mask constant at an overlap between the unit mask elements. Accordingly, the mask frame assembly reduces distortion in an evaporation pattern due to an increase in the size of a mask pattern, facilitates the adjustment of a total pitch of evaporation patterns, and prevents evaporation from occurring at undesired positions.Type: GrantFiled: June 3, 2003Date of Patent: October 18, 2005Assignee: Samsung SDI Co., Ltd.Inventors: Chang Ho Kang, Tae Seung Kim
