Publication number: 20070231941Abstract: An organic device element including a high-quality protective film is manufactured. In a step of forming a protective film on an organic device substrate on which an organic device is formed, an electroconductive rear plate provided on a rear side of the organic device substrate is divided into a peripheral portion which is in contact with a substrate circumference portion and a central portion which is in contact with a substrate central portion. A bias voltage of ?10 V is applied to the central portion and a bias voltage of ?5 V is applied to the peripheral portion. Therefore, an electric field intensity of a surface of the organic device substrate caused by a discharge unit is made uniform over the entire substrate to reduce a film thickness distribution of the formed protective film to ±2%.Type: ApplicationFiled: March 14, 2007Publication date: October 4, 2007Applicant: CANON KABUSHIKI KAISHAInventor: Hiroshi Sugai
