Publication number: 20110237886Abstract: An imaging unit includes an objective optical system, an image sensor, a cover glass, a prism, and a heat conduction portion. The objective optical system imports light of an image of a subject. The image sensor forms an image of the light and outputs an imaging signal. The cover glass is provided on an imaging surface of the image sensor and seals the image sensor air-tightly. The prism is disposed between the objective optical system and the cover glass so as to guide the light from the objective optical system to the imaging surface. The heat conduction portion touches the prism and extends from the prism towards the image sensor so as to transmit heat of the image sensor to the prism.Type: ApplicationFiled: January 31, 2011Publication date: September 29, 2011Applicant: FUJIFILM CORPORATIONInventors: Goki YAMAMOTO, Kazuaki TAKAHASHI, Kosuke TAKASAKI

Patent number: 7988803Abstract: A device for joining substrates (11) is provided inside a clean booth (12). a single axis robot (46) and a five axis robot (47) convey a wafer (25) and a glass substrate (33). A transcribing station (91) obtains a transcribing film (112) on which adhesive is applied from a film supplying section (113), and presses the transcribing film (112) to the glass substrate (33) so as to transcribe the adhesive to the glass substrate (33). A peeling station (92) peels the transcribing film (112) from the glass substrate (33). A joining station (57) positions the wafer (25) and the glass substrate (33), adjusts parallelism of joining surfaces of the wafer (25) and the glass substrate (33), and joins these substrates together. Since the handling and the joining of the wafer (25), the glass substrate (33) and the transcribing film (112) are performed in the clean booth, it is prevented that a yield ratio of the product decreases because of the adhesion of foreign matters.Type: GrantFiled: January 8, 2010Date of Patent: August 2, 2011Assignee: Fujifilm CorporationInventors: Kosuke Takasaki, Kiyofumi Yamamoto, Kazuo Okutsu, Koji Tsujimura

Publication number: 20100060757Abstract: A solid-state image pickup device (1) comprises: an image sensor wafer (2A) including image sensors (3); an optically-transparent protection member (4) connected by use of an adhesive agent (7) via a spacer (5) arranged to surround the image sensors (3); and an electrostatic (ESD) protection circuit (10) disposed on the image sensor wafer (2A) so as to avoid a position corresponding to a connected surface where the spacer (5) and the image sensor wafer (2A) are connected. Accordingly, in this configuration, even when polarization occurs in the adhesive agent, since the p-well layer between diffusion layers of the ESD protection circuit is not disposed immediately below the connected surface, the p-well layer is not inverted by electric charges in the element interface and thus parasitic MOS transistor does not turn on, allowing suppression of leak current.Type: ApplicationFiled: December 10, 2007Publication date: March 11, 2010Applicant: FUJIFILM CorporationInventors: Kosuke Takasaki, Mamoru Iesaka, Hideki Wako

Patent number: 7651881Abstract: A transfer film, on which an adhesive is applied, is glued to plural spacers formed on a glass substrate. The glass substrate is laid on a working table, and one end of the transfer film is fixed to a winding roller. A peeling guide is set at a position over the transfer film. The winding roller is driven to wind the transfer film while the working table moves horizontally. While winding the transfer film, the angle between the glass substrate and the transfer film is kept constant. After the transfer film is peeled off, the adhesive is uniformly transferred to each of the spacers.Type: GrantFiled: March 24, 2004Date of Patent: January 26, 2010Assignee: FUJIFILM CorporationInventors: Kosuke Takasaki, Kazuhiro Nishida, Kiyofumi Yamamoto
