Patent ID: 8355069

Claim:
A solid-state image pickup device comprising: a plurality of pixels each including a photoelectric conversion unit having a plurality of transistors, the plurality of pixels being diagonally arranged; wiring extending in vertical and horizontal directions, the wiring being diagonally arranged, and further wherein a vertical signal line and well contact line extend in the vertical direction, at least one of the vertical signal line and well contact line having linear diagonal portions formed immediately adjacent corresponding boundary portions of the photoelectric conversion unit without any signal line or electronic component therebetween, such that the well contact line and vertical signal line are formed at opposite sides of each pixel and each of the vertical signal line and well contact line has portions immediately adjacent boundary portions of the photoelectric conversion unit and there being two sets of well contact lines and vertical signal lines in a common level located between horizontally adjacent pixels and only a single vertical signal line and a single well contact line located in the common level in region between two diagonally adjacent pixels; and wherein for each of the plurality of pixels, at least one among the plurality of transistors is shared by two or more photoelectric conversion units which are diagonally arranged.
