Patent ID: 8488735

Claim:
A solid-state imaging device which comprises a photodetecting section having M×N pixel portions P 1,1 to P M,N two-dimensionally arrayed so as to form a matrix of M rows and N columns, each of the pixel portions P 1,1 to P M,N including a photodiode that generates charge of an amount according to an incident light intensity, and a reading-out switch connected to the photodiode, each of the M and N being an integer not less than 2, wherein the photodiode, included in a pixel portion P m,n of the photodetecting section, is constituted by a first semiconductor region having a first conductivity type, and a second semiconductor region which has a second conductivity type and is formed on the first semiconductor region, the m being an integer not less than 1 and not more than M, the n being an integer not less than 1 and not more than N, wherein the photodetecting section has a channel stopper provided in a region sandwiched by each of the pixel portions P 1,1 to P M,N , the channel stopper being constituted by a third semiconductor region which has the first conductivity type and a higher impurity concentration than that of the first semiconductor region, and wherein the photodetecting section includes plural first dummy photodiodes arranged around one pixel portion without completely surrounding the one pixel portion, the each first dummy photodiode provided in a region surrounded by any 2×2 pixel portions adjacent to one another of the pixel portions P 1,1 to P M,N , while being surrounded by the channel stopper, the each first dummy photodiode being constituted by the first semiconductor region, and a fourth semiconductor region which has the second conductivity type and is formed on the first semiconductor region.
