Patent ID: 7440019

Claim:
A solid-state image pick-up device having a plurality of photoelectric converting devices arranged in a row direction and a column direction orthogonal thereto over a surface of a semiconductor substrate, comprising: a vertical transfer section for transferring charges from the photoelectric converting devices in the column direction; a horizontal transfer section for transferring the charges from the vertical transfer section in the row direction; and an output section for outputting a signal corresponding to a charge transferred through the horizontal transfer section, wherein the photoelectric converting device includes a plurality of high-sensitivity photoelectric converting devices arranged like a tetragonal grid in the row direction and the column direction orthogonal thereto and serving to carry out a photoelectric conversion having a relatively high sensitivity, and a plurality of low-sensitivity photoelectric converting devices arranged like the tetragonal grid in the row direction and the column direction orthogonal thereto and serving to carry out a photoelectric conversion having a relatively low sensitivity, the high-sensitivity photoelectric converting devices and the low-sensitivity photoelectric converting devices are arranged at an equal array pitch in positions shifted by ½ of the array pitch from each other in the row direction and the column direction, the vertical transfer section includes a plurality of vertical transfer channels formed on the semiconductor substrate corresponding to the photoelectric converting devices provided in the column direction, a plurality of vertical transfer electrodes formed to cross each of the vertical transfer channels as seen on a plane, and a charge reading regions for reading the charges of the photoelectric converting devices onto the vertical transfer channels, each of the vertical transfer channels takes a winding shape extended wholly in the column direction between the photoelectric converting devices, each of the vertical transfer electrodes takes a winding shape extended wholly in the row direction between the photoelectric converting devices, the charge reading regions of the photoelectric converting devices which are adjacent to each other in the column direction are formed between the adjacent photoelectric converting devices and the vertical transfer channels which are different from each other, four vertical transfer electrodes are provided corresponding to one of the photoelectric converting devices adjacent to each other in the column direction, other four vertical transfer electrodes are provided corresponding to the other of the photoelectric devices adjacent to each other in the column direction, and the vertical transfer electrodes are driven by vertical transfer pulses having eight phases.
