Patent number: 8115208Abstract: An image display system and manufacturing method are disclosed. According to the present invention, the image display system comprises a substrate, a switching TFT, a driving TFT, a photo sensor and a capacitor. A buffer layer is formed on a substrate. A separation layer is formed in a first area for forming a switching TFT, but no heat sink layer is formed thereon. A heat sink layer is formed on a second area for forming the driving TFT, the photo sensor and the capacitor, and then, the separation layer is formed thereafter. The present invention can form poly silicon layers with different crystal grain sizes on the first area and on the second area in a single laser crystallization process by utilizing the heat sink phenomenon of ELA with or without the heat sink layer. Therefore, the image display system of the present invention can operate with good luminance uniformity.Type: GrantFiled: April 29, 2009Date of Patent: February 14, 2012Assignee: Chimei Innolux CorporationInventors: Yu-chung Liu, Te-yu Lee

Publication number: 20110312183Abstract: For patterning during integrated circuit fabrication, a first pattern of first masking structures is formed, and a buffer layer is formed on exposed surfaces of the first masking structures. Also, a second pattern of second masking structures is formed in recesses between the buffer layer at sidewalls of the first masking structures. Furthermore, the first and masking structures are formed from spin-coating respective high carbon containing materials. Such first and second masking structures pattern a target layer with higher pitch than possible with traditional photolithography.Type: ApplicationFiled: August 25, 2011Publication date: December 22, 2011Inventors: Shi-Yong Yi, Myeong-Cheol Kim, Dong-Ki Yoon, Kyung-Yub Jeon, Ji-Hoon Cha

Publication number: 20110312190Abstract: A coating method based on such a technique includes a prewetting step of supplying a prewetting liquid to the center of a substrate (W) and rotating the substrate thereby spreading the prewetting liquid over the whole surface of a first substrate, and a coating film forming step of supplying a coating solution (e.g., a resist solution) to the substrate supplied with the prewetting liquid and drying the coating solution thereby forming a coating film on the surface of the first substrate. The prewetting liquid used is a mixed liquid obtained by mixing a solvent capable of dissolving components of the coating film (e.g., components of resist) and a high surface tension liquid having a surface tension higher than that of the solvent, the mixed liquid having a surface tension higher than that of the coating solution.Type: ApplicationFiled: June 16, 2011Publication date: December 22, 2011Applicant: Tokyo Electron LimitedInventors: Katsunori Ichino, Kentaro Yoshihara, Kousuke Yoshihara

Patent number: RE43045Abstract: In one embodiment the present invention is a method of conducting multiple step multiple chamber chemical vapor deposition while avoiding reactant memory in the relevant reaction chambers. The method includes depositing a layer of semiconductor material on a substrate using vapor deposition in a first deposition chamber followed by evacuation of the growth chamber to reduce vapor deposition source gases remaining in the first deposition chamber after the deposition growth and prior to opening the chamber. The substrate is transferred to a second deposition chamber while isolating the first deposition chamber from the second deposition chamber to prevent reactants present in the first chamber from affecting deposition in the second chamber and while maintaining an ambient that minimizes or eliminates growth stop effects. After the transferring step, an additional layer of a different semiconductor material is deposited on the first deposited layer in the second chamber using vapor deposition.Type: GrantFiled: May 5, 2010Date of Patent: December 27, 2011Assignee: Cree, Inc.Inventor: David Todd Emerson
