Publication number: 20110239941Abstract: Provided is an evaporation apparatus which reduces deformation of a mask, improves adhesion between a substrate and an evaporation mask, and improves accuracy of dividing a region on which a film is to be formed and a region on which the film is not to be formed. The evaporation apparatus includes a pressing mechanism for pressing a film forming substrate disposed on an evaporation mask including a magnetic material against the evaporation mask. The pressing mechanism includes a magnet for attracting the mask toward at least a corner portion of the film forming substrate.Type: ApplicationFiled: March 29, 2011Publication date: October 6, 2011Applicant: CANON KABUSHIKI KAISHAInventors: Yoshiyuki Nakagawa, Masanori Yoshida, Masamichi Masuda, Junji Ohyama, Akio Koganei, Naotoshi Miyamachi, Hirohito Yamaguchi, Tetsuya Karaki, Nobutaka Ukigaya, Toshiaki Yoshikawa

Patent number: 6949174Abstract: A milling apparatus is provided in which temperature rise of a treatment-object in milling treatment, especially of the substrate thereof, is prevented. In the apparatus, ionization mechanism 2 comprises casing 20d having an opening at the center portion of the face thereof opposing to substrate 5 held by substrate holder 6; a filament is placed at the position where the straight line drawn from the filament to substrate 5 is intercepted by casing 20d; and electromagnets 31, 32 are provided around ionization mechanism 2 for generating a magnetic field to produce magnetic lines extending through opening 20j to substrate 5.Type: GrantFiled: May 27, 2003Date of Patent: September 27, 2005Assignee: Canon Kabushiki KaishaInventors: Hirohito Yamaguchi, Masahiro Kanai, Atsushi Koike, Katsunori Oya

Patent number: 6878241Abstract: Sputtering particles emitted from a target are ionized by the Penning ionization process. And the sputtering particles ionized are caused to fly in the direction of the substrate by a magnetic field formed by ambipolar diffusion due to a magnetic field generating means without scattering the particles to deposit the particles on the substrate. The partial pressure of a sputtering discharge gas in a discharge space is set to 1.3 Pa or less and a distance from the target to an ionization space is within twice the mean free path of the partial pressure of the sputtering discharge gas.Type: GrantFiled: April 9, 2003Date of Patent: April 12, 2005Assignee: Canon Kabushiki KaishaInventors: Hirohito Yamaguchi, Masahiro Kanai, Atsushi Koike, Katsunori Oya
