| 20090072123 | Solid-state imaging device and drive control method for the same - A CMOS sensor has unit pixels each structured by a light receiving element and three transistors, to prevent against the phenomenon of saturation shading and the reduction of dynamic range. The transition time (fall time), in switching off the voltage on a drain line shared in all pixels, is given longer than the transition time in turning of any of the reset line and the transfer line. For this reason, the transistor constituting a DRN drive buffer is made proper in its W/L ratio. Meanwhile, a control resistance or current source is inserted on a line to the GND, to make proper the operation current during driving. This reduces saturation shading amount. By making a reset transistor in a depression type, the leak current to a floating diffusion is suppressed to broaden the dynamic range. | 03-19-2009 |

| 20100123240 | SEMICONDUCTOR DEVICE AND MANUFACTURING METHOD THEREOF - A semiconductor device is provided with improved reliability. A semiconductor chip is mounted over a chip mounting portion of a lead frame via solder. A metal plate is arranged over a source pad of the semiconductor chip and a lead portion of a lead frame via solder. A solder reflow process is performed thereby to bond the semiconductor chip over the chip mounting portion with a solder, and to bond the metal plate to the source pad and the lead portion with the other solders. The lead frame is formed of a copper alloy, and thus has its softening temperature higher than the temperature of the solder reflow process. The metal plate is formed of oxygen-free copper, and has its softening temperature lower than the temperature of the solder reflow process, whereby the metal plate is softened in the solder reflow process. Thereafter, a gate pad electrode of the semiconductor chip is coupled to a lead portion via the wire, a sealing resin portion is formed, and then the lead frame is cut. | 05-20-2010 |
