Publication number: 20240105656Abstract: A packaging device including bumps and a method of manufacturing the packaging device are presented. In the method of manufacturing a packaging device, a dielectric layer that covers a packaging base is formed and a lower layer is formed over a packaging base including first and second connecting pads. A plurality of dummy bumps that overlaps with the dielectric layer is formed. A sealing pattern that covers the dummy bumps, filling areas between the dummy bumps, is formed. A lower layer pattern in which the plurality of dummy bumps have been disposed is formed by removing portions of the lower layer that are exposed and do not overlap with the sealing pattern.Type: ApplicationFiled: March 20, 2023Publication date: March 28, 2024Applicant: SK hynix Inc.Inventors: Jae Jun LEE, Jong Yeon KIM, Jong Hoon KIM, Ju Heon YANG, Mi Seon LEE

Patent number: 8337614Abstract: The surface of a gallium nitride single crystal substrate is processed, e.g., comprising steps by planarizing the top side and the bottom side of a gallium nitride original substrate positioned on a support bed; radiating light having wavelengths ranging from 370 to 800 nanometers (nm) onto the planarized gallium nitride original substrate; measuring transmittance of the gallium nitride original substrate; and confirming whether the transmittance is within the range of 65 to 90%. A gallium nitride single crystal substrate obtained through the method of processing the surface has high transmittance ranging from 65 to 90% measured using light having wavelengths of 370 to 800 nm. The thickness ratio (DLa/DLb) of the damage layers on the both sides of the gallium nitride single crystal substrate can be obtained within the range of 0.99 to 1.01.Type: GrantFiled: October 29, 2007Date of Patent: December 25, 2012Assignee: Samsung Corning Precision Materials Co., Ltd.Inventors: Jin Suk Jeong, Ki Soo Lee, Kyoung Jun Kim, Ju Heon Lee, Chang Uk Jin

Publication number: 20110295660Abstract: Disclosed herein is a mobile advertisement processing method. The method is performed by a mobile terminal and an advertisement server connected over a network to an application server for providing an application. An advertisement to be exposed on the application and an advertisement completion condition are set. Advertisement data to be played on the application is provided in response to a request of the application run in the mobile terminal. Notification of whether the user has recognized the advertisement is received through the application, and exposures of the advertisement are totalized. Accordingly, the present invention prevents users from getting tired with application-based mobile advertisements, and allows the users to positively respond to mobile advertisements, thus improving advertising effects.Type: ApplicationFiled: October 27, 2010Publication date: December 1, 2011Applicant: CoSTEP Co., Ltd.Inventor: Ju Heon Lee
