  • Patent number: 8338248
    Abstract: A semiconductor element includes: a p-type semiconductor region; an n-type light-receiving surface buried region buried in the semiconductor region; an n-type charge accumulation region buried in the semiconductor region, continuously to the light-receiving surface buried region, establishing a deeper potential well depth than the light-receiving surface buried region; a charge read-out region configured to read out the charges accumulated in the charge accumulation region; an exhaust-drain region buried in the semiconductor region, configured to extract the charges from the light-receiving surface buried region; a first potential controller configured to extract the charges from the light-receiving surface buried region to the exhaust-drain region; and a second potential controller configured to transfer the charges from the charge accumulation region to the charge read-out region.

  • Patent number: 8169799
    Abstract: A power factor correction circuit steps up and power-factor-corrects a rectified voltage, which has been rectified from an AC input voltage of an AC power source Vin, through an ON/OFF operation of a switching element Q1 and supplies a stepped-up output voltage to a DC-DC converter that is driven with a first pulse signal. The power factor correction circuit includes a delay circuit to receive the first pulse signal whose pulse width corresponds to an output voltage of the DC-DC converter, generate, in response to an ON pulse of the first pulse signal, a delay pulse signal whose pulse width corresponds to the rectified voltage, and synthesize the first pulse signal and the delay pulse signal into a second pulse signal. The power factor correction circuit also includes a driver to drive the switching element according to the second pulse signal.

  • Patent number: 7781131
    Abstract: A positive-type photosensitive resin composition comprises (A) an alkali-soluble resin having at least a polybenzoxazole precursor structure, (B) a sensitizer, and (C) a cyclic compound having an alcoholic hydroxyl group. A protecting layer and an insulating layer include a cured layer which is a cured product of the positive-type photosensitive resin composition. A semiconductor device and a display device include the cured layer. According to the present invention, a highly reliable positive-type photosensitive resin composition can be obtained even when cured at a low temperature.
