    Abstract: An image sensor is provided to enable two adjacent pixels to share one OG and one OD to increase a fill factor, thereby improving the optical sensitivity of the image sensor. An image sensor includes a CCL(Common Column Line) and pixels(PX). The pixels are connected to the CCL in parallel. Each of the pixels includes a photoelectric conversion area, a TG(Transfer Gate), an OG(Overflow Gate), and an OD(Overflow Drain Area). The TG is disposed between the photoelectric conversion area and the CCL. The OG is spaced from the TG with the photoelectric conversion area. The OD is positioned oppositely to the photoelectric conversion area with the OG. Two adjacent pixels share one OG and one OD. An overflow transistor(MO) discharges unnecessary photoelectric charges, which a PD(Photo Diode) can not receive at a predetermined storage capacitance, to a VDD(Voltage Drain Drain) terminal. A transfer transistor(MT) only transmits photoelectric charges to an output terminal. The MT receives a transmission gate signal. A source follower transistor(MD) and a reset transistor(MR) are connected to the CCL.

    Abstract: An image sensor, a manufacturing method thereof, and an image sensing method are provided to suppress a crosstalk due to a random drift of charges by forming a potential barrier on a lower substrate region. A photoelectric converter(110) is formed in a semiconductor substrate(101) with a depth between 1 and 3 mum and includes a photodiode with a second conductivity type and a capping layer with a first conductivity type. The photodiode accumulates charges corresponding to an incident beam. The capping layer is formed on the photodiode. A charge detector(120) receives the accumulated charges from the photoelectric converter and converts the charges into an electrical signal. A charge transfer part(130) delivers the accumulated charges to the charge detector. A voltage application unit(Vb) applies voltages on the capping layer and a lower portion of the semiconductor substrate, such that a width of a depletion layer is adjusted. The depletion layer is formed on the photodiode.

    Abstract: A beam forming apparatus for reflecting characteristics of an actual noise environment and a method thereof are provided to effectively apply a voice interface technology used between mobile devices to an environment having a noise. A beam forming apparatus for reflecting characteristics of an actual noise environment includes a microphone array(300) and a beam forming unit(310). The microphone array is composed of at least one microphone(300-1~300-N) to output an input signal inputted through the microphone. The beam forming unit has a coherence function generation unit(312), a spatial filter coefficient calculation unit(320), and a beam forming performing unit(322). The coherence function generating unit calculates the average of coherences in accordance with the same distance after the coherences are calculated according to each microphone interval with respect to the input signal. After the coherence function generating unit filters the calculated average coherences, the coherence function generating unit outputs the filtered value. The spatial filter coefficient calculation unit calculates a spatial filter coefficient by using the filtered average coherences to output. The beam forming performing unit outputs the noise processed signals by performing the beam forming for the input signal by using the spatial filter coefficient.
