Patent number: 7297566Abstract: A display device is formed by burying at least part of a light emitting device in an insulating material, wherein a drive electrode for the light emitting device is formed so as to be extracted on a surface of the insulating material. A display unit is produced by two-dimensionally arraying such light emitting devices on a base body. Since the display device is modularized by burying a light emitting device finely formed in an insulating material, to re-shape the light emitting device into a size easy to handle, it is possible to suppress the production cost of the display unit using such display devices, and to ensure a desirable handling performance of the light emitting device; for example, facilitate the carrying of the light emitting device or the mounting thereof on a base body.Type: GrantFiled: April 11, 2005Date of Patent: November 20, 2007Assignee: Sony CorporationInventors: Toyoharu Oohata, Hideharu Nakajima, Yoshiyuki Yanagisawa, Toshiaki Iwafuchi

Patent number: 7233030Abstract: A device transfer method includes the steps of: covering a plurality of devices, which have been formed on a substrate, with a resin layer; forming electrodes in the resin layer in such a manner that the electrodes are connected to the devices; cutting the resin layer, to obtain resin buried devices each containing at least one of the devices; and peeling the resin buried devices from the substrate and transferring them to a device transfer body. This device transfer method is advantageous in easily, smoothly separating devices from each other, and facilitating handling of the devices in a transfer step and ensuring good electric connection between the devices and external wiring, even if the devices are fine devices.Type: GrantFiled: December 23, 2003Date of Patent: June 19, 2007Assignee: Sony CorporationInventors: Yoshiyuki Yanagisawa, Toyoharu Oohata, Toshiaki Iwafuchi

Patent number: 7205214Abstract: A method of selectively transferring devices arrayed on a first substrate to a second substrate on which an adhesive resin layer is previously formed is provided. The method includes steps of selectively heating the adhesive resin layer on the second substrate by laser irradiation from the back surface side of the second substrate, and curing the selectively heated portions of the adhesive resin layer, thereby adhesively bonding those to be transferred of the devices to the second substrate. At this time, portions, corresponding to the devices, of the adhesive layer are heated directly or indirectly via the devices or wiring portions by laser irradiation from the back surface side of the substrate. The heated portions of the adhesive resin layer selectively exhibit the adhesive forces. The heated portions of the adhesive layer are then cured, so that only the devices to be transferred are selectively transferred to the second substrate.Type: GrantFiled: March 14, 2005Date of Patent: April 17, 2007Assignee: Sony CorporationInventors: Kunihiko Hayashi, Yoshiyuki Yanagisawa, Toshiaki Iwafuchi, Hisashi Ohba
