A great number of blades are disposed in a shell inside with appropriate distances left between them in a circumferential direction of a shell. Each blade has an approximately fan-shaped blade body and a flange protruding from an inner peripheral edge in a prescribed direction along a circumference of a shell. An outer peripheral edge of each blade is secured to the shell. The flange of each blade is made contact with a neighboring blade over the entire circumferential length of the blade, and these contacting portions are secured each other in a watertight manner. A core ring is not installed.

A solid-state image sensor includes: a semiconductor substrate 22; a plurality of pixels 23 arranged on the semiconductor substrate 22 and respectively including photoelectric conversion regions 24; and an isolation region 25 electrically isolating the pixels 23 from one another. The first pixel 31 includes a first photoelectric conversion region 32 and a first color filter 41 having a peak of its optical transmission in a first wavelength range. The second pixel 34 adjacent to the first pixel 31 includes a second photoelectric conversion region 35 and a second color filter 42 having peaks in its optical transmission in the first wavelength range and a second wavelength range including shorter wavelengths than the first wavelength range. A portion 33 of a deep portion of the first photoelectric conversion region 32 extends across the isolation region 25 to reach a portion under the second photoelectric conversion region 35.

A solid-state imaging element includes a layered substrate made of silicon and composed of, for example, an N-type substrate, a P-type layer, and an N-type layer. In the layered substrate, an imaging region in which a plurality of pixels are arranged and a peripheral circuit region are formed. A recess reaching the reverse face of the P-type layer is formed in a reverse face portion of the layered substrate in the imaging region, and a reflective film is formed on at least the inner face of the recess. Light is reflected on the reverse face and the obverse face of the layered substrate.

In each of pixels 10 arranged in an array pattern, an insulating isolation part 22 electrically isolates adjacent photoelectric conversion elements 11, and the photoelectric conversion element 11 and an amplifier transistor 14. The insulating isolation part 22 constitutes a first region A between the photoelectric conversion elements 11 where the amplifier transistor 14 is not arranged, and a second region B between the photoelectric conversion elements 11 where the amplifier transistor 14 is arranged. A low concentration first isolation diffusion layer 23 is formed below the insulating isolation part 22 constituting the first region A, and a high concentration second isolation diffusion layer 24 and a low concentration first isolation diffusion layer 23 are formed below the insulating isolation part 22 constituting the second region B. A source/drain region of the amplifier transistor 14 in the second region B is formed in a well region 25 formed simultaneously with the second isolation diffusion layer 24.
摘要:
A plurality of pixel portions (12) are formed on a silicon substrate (11). A photoelectric converter portion (10) constituting each of the pixel portions (12) is electrically isolated by an element isolation portion (13) comprising an insulating film formed on the silicon substrate (11). The photoelectric converter portion (10) partitioned by the element isolation portion (13) is so formed that a crystal orientation of the sides in contact with the element isolation portion (13) corresponds to a direction. This makes it possible to reduce dark current caused by stress in the vicinity of the interface of the element isolation portion (13) and maintain high sensitivity even if the pixel portions (12) are made smaller in size.
