Patent number: 7646042Abstract: When capacity coupling between an output gate electrode (OG) and a last-stage transfer electrode is large at an output end of a CCD shift register, an electric potential of the OG is varied according to transfer clocks with the result that noise is liable to generate in an output signal. As measures for this, convex portions projecting horizontally are formed in those positions of the last-stage transfer electrode and the OG, which correspond to a channel region, and overlap between the electrodes is caused only on the convex portions. A clearance is formed between the OG and the transfer electrode except those locations, in which the convex portions are provided. In that location, in which the OG and the transfer electrode, respectively, are extended relatively lengthily toward wirings, the electrodes do not overlap each other. In this manner, capacity coupling between the electrodes is reduced.Type: GrantFiled: January 19, 2006Date of Patent: January 12, 2010Assignee: Sanyo Electric Co., Ltd.Inventor: Takahiko Ogo

Patent number: 7537957Abstract: A solid state imaging device and a method for manufacturing the same that prevents the reproduction characteristic of an optical image from being affected by diagonal light on a semiconductor substrate surface. A CCD image sensor includes a semiconductor substrate, light receiving pixels formed on the semiconductor substrate, and a color filter arranged above the light receiving pixels and including filters transmitting light having different wavelengths. Dummy wires, which shield light that passes through the color filter and which are electrically isolated from clock wires, are arranged at locations corresponding to boundaries of regions, each defining one of the light receiving pixels.Type: GrantFiled: May 29, 2007Date of Patent: May 26, 2009Assignee: Sanyo Electric Co., Ltd.Inventors: Hidetaka Nishimura, Takahiko Ogo

Patent number: 7538811Abstract: In an image pickup portion of a frame transfer CCD image sensor, a constitution that inhibits color mixing from occurring between light-sensitive pixels adjacent along a vertical CCD shift register channel is provided. A protrusion extending on the channel is formed at a clock wiring formed on a channel stop of the vertical CCD shift register with an wiring layer having the light-shielding property. When the protrusion portion is disposed at a boundary of light-sensitive pixels in the channel, a non-light-shielding portion generated at the boundary can be suppressed. The protrusions are disposed so as to alternately protrude from the clock wirings on both sides of the channel.Type: GrantFiled: August 29, 2005Date of Patent: May 26, 2009Assignee: Sanyo Electric Co., Ltd.Inventors: Takahiko Ogo, Shinichiro Izawa, Kazutaka Itsumi
