An imaging circuit ( ) is formed on a semiconductor substrate ( ) having first and second regions ( ) for capturing a light signal (LIGHT) to produce first and second charges, respectively. A conductive material ( ) is extended from the first region to the second region for controlling the first and second charges in response to a control signal (COL , ROW ) to produce an output signal (V ) of the imaging circuit.

Imaging device and method

An electronic component having an image sensing device ( ) and a method for improving pixel charge transfer in the image sensing device ( ). The image sensing device ( ) has a transfer gate ( ) between a source region ( ) and an image sensing region. The image sensing region is formed to have a wider device width proximate to the transfer gate ( ) than at a point distal from the transfer gate ( ).

Electronic component and method for improving pixel charge transfer in the electronic component

An image sensor (,) has an image sensing element that includes an N-type conducting region (,) and a P-type pinned layer (,). The two regions form two P-N junctions at different depths that increase the efficiency of charge carrier collection at different frequencies of light. The conducting region (,) is formed by an angle implant that ensures that a portion of the conducting region (,) can function as a source of a MOS transistor (,).

Method of making a semiconductor image sensor

An image sensor (10) has an image sensing element that includes an N-type conducting region (26) and a P-type pinned layer (37). The two regions form two P-N junctions at different depths that increase the efficiency of charge carrier collection at different frequencies of light. The conducting region (26) is formed by an angle implant that ensures that a portion of the conducting region (26) can function as a source of an MOS transistor (32).
