Abstract:
1. A solid-state imaging device comprising: a photosensitive region having cells two-dimensionally arranged in row and column directions on a semiconductor substrate, each of the cells including a photodiode, a transfer transistor, a floating diffusion layer, an amplifier transistor, and a reset transistors a power supply line commonly connected to drains of said amplifier transistors; and a plurality of vertical signal lines each commonly connected to said amplifier transistors arranged in a same column, wherein: the floating diffusion layer included in a given one of the cells is connected to a gate of an amplifier transistor included in a cell adjacent to the given cell in a direction other than the row direction, in each cell, the floating diffusion layer and the reset transistor share a portion in an active region, and the amplifier transistor and the reset transistor share another portion in the active region, the power supply line and the vertical signal lines are made of a same wiring material, a first contact is provided on the floating diffusion layer so as to connect the floating diffusion layer with a gate of the amplifier transistor, a second contact is connected to the power supply line, a third contact is connected to the vertical signal line and the first contact, the second contact, and the third contact are aligned substantially in a straight line.
