Patent number: 8138502Abstract: To prevent a point defect and a line defect in forming a light-emitting device, thereby improving the yield. A light-emitting element and a driver circuit of the light-emitting element, which are provided over different substrates, are electrically connected. That is, a light-emitting element and a driver circuit of the light-emitting element are formed over different substrates first, and then electrically connected. By providing a light-emitting element and a driver circuit of the light-emitting element over different substrates, the step of forming the light-emitting element and the step of forming the driver circuit of the light-emitting element can be performed separately. Therefore, degrees of freedom of each step can be increased, and the process can be flexibly changed. Further, steps (irregularities) on the surface for forming the light-emitting element can be reduced than in the conventional technique.Type: GrantFiled: July 25, 2006Date of Patent: March 20, 2012Assignee: Semiconductor Energy Laboratory Co., Ltd.Inventors: Osamu Nakamura, Miyuki Higuchi, Yasuko Watanabe, Yasuyuki Arai

Patent number: 8134149Abstract: The present invention has an object of providing a light emitting device including an OLED formed on a plastic substrate, which can prevent the degradation due to penetration of moisture or oxygen. On a plastic substrate, a plurality of films for preventing oxygen or moisture from penetrating into an organic light emitting layer in the OLED (hereinafter, referred to as barrier films) and a film having a smaller stress than that of the barrier films (hereinafter, referred to as a stress relaxing film), the film being interposed between the barrier films, are provided. Owing to a laminate structure of a plurality of barrier films, even if a crack occurs in one of the barrier films, the other barrier film(s) can effectively prevent moisture or oxygen from penetrating into the organic light emitting layer. Moreover, the stress relaxing film, which has a smaller stress than that of the barrier films, is interposed between the barrier films, thereby making it possible to reduce a stress of the entire sealing film.Type: GrantFiled: May 16, 2011Date of Patent: March 13, 2012Assignee: Semiconductor Energy Laboratory Co., Ltd.Inventors: Shunpei Yamazaki, Toru Takayama, Mai Akiba

Patent number: 8129272Abstract: A strengthened semiconductor die substrate and package are disclosed. The substrate may include contact fingers formed with nonlinear edges. Providing a nonlinear contour to the contact finger edges reduces the mechanical stress exerted on the semiconductor die which would otherwise occur with straight edges to the contact fingers. The substrate may additionally or alternatively include plating traces extending at an angle from the contact fingers. Extending at an angle, at least the ends of the plating traces at the edge of the substrate are covered beneath a lid in which the semiconductor package is encased. Thus, when in use with a host device, contact between the ends of the plating traces beneath the lid and contact pins of the host device is avoided.Type: GrantFiled: June 29, 2009Date of Patent: March 6, 2012Assignee: SanDisk Technologies Inc.Inventors: Hem Takiar, Cheeman Yu, Ken Jian Ming Wang, Chin-Tien Chiu, Han-Shiao Chen, Chih-Chin Liao

Patent number: 8129823Abstract: Highly reliable interconnections for microelectronic packaging. In one embodiment, dielectric layers in a build-up interconnect have a gradation in glass transition temperature; and the later applied dielectric layers are laminated at temperatures lower than the glass transition temperatures of the earlier applied dielectric layers. In one embodiment, the glass transition temperatures of earlier applied dielectric films in a build-up interconnect are increased through a thermosetting process to exceed the temperature for laminating the later applied dielectric films. In one embodiment, a polyimide material is formed with embedded catalysts to promote cross-linking after a film of the polyimide material is laminated (e.g., through photo-chemical or thermal degradation of the encapsulant of the catalysts).Type: GrantFiled: November 27, 2007Date of Patent: March 6, 2012Assignee: Intel CorporationInventor: Ravindra V.

Publication number: 20110260147Abstract: The present invention relates to an organic/inorganic hybrid thin film passivation layer comprising an organic polymer passivation layer prepared by a UV/ozone curing process and an inorganic thin film passivation layer for blocking moisture and oxygen transmission of an organic electronic device fabricated on a substrate and improving gas barrier property of a plastic substrate; and a fabrication method thereof. Since the organic/inorganic hybrid thin film passivation layer of the present invention converts the surface polarity of an organic polymer passivation layer into hydrophilic by using the UV/ozone curing process, it can improve the adhesion strength between the passivation layer interfaces, increase the light transmission rate due to surface planarization of the organic polymer passivation layer, and enhance gas barrier property by effectively blocking moisture and oxygen transmission.Type: ApplicationFiled: April 20, 2011Publication date: October 27, 2011Inventors: Jai Kyeong Kim, Jung Soo Park, June Whan Choi, Dae-Seok Na, Jae-Hyun Lim, Joo-Won Lee
