Publication number: 20120285379Abstract: Demands such as higher definition, higher opening aperture, and higher reliability on a full-color flat panel display have been increased. Such demands are big objects in advancing higher definition (increase in the number of pixels) of a light-emitting device and miniaturization of each display pixel pitch with reduction in size of the light-emitting device. An organic compound-containing layer is selectively deposited using a laser beam which passes through openings of a mask. An irradiated substrate provided with a light absorption layer and a material layer containing an organic compound and a deposition substrate provided with first electrodes are placed so as to face each other. The light absorption layer is heated by a laser beam which has passed through the openings of the mask, and the organic compound at a position overlapping with the heated region is vaporized, and accordingly the organic compound is selectively deposited over the deposition substrate.Type: ApplicationFiled: July 26, 2012Publication date: November 15, 2012Inventors: Yoshiharu Hirakata, Hisao Ikeda, Takahiro Ibe, Shunpei Yamazaki

Patent number: 8252378Abstract: To improve the use efficiency of a vapor-deposition material, reduce the manufacturing cost of a light-emitting device including a layer containing an organic compound, and shorten the manufacturing time for manufacturing a light-emitting device. Inside of a film formation chamber is made in a reduced pressure state, and conductive-surface substrate is energized, so that the conductive-surface substrate is heated rapidly, and a material layer over the conductive-surface substrate is evaporated in a short period of time to be vapor-deposited on a film formation substrate, whereby film formation of the material layer is performed on the film formation substrate. Note that the heating area of the conductive-surface substrate which is rapidly heated is set to be the same size as the film formation substrate so that film formation on one film formation substrate is completed by one heating.Type: GrantFiled: March 12, 2008Date of Patent: August 28, 2012Assignee: Semiconductor Energy Laboratory Co., Ltd.Inventors: Takahiro Ibe, Hisao Ikeda
