    • The solid-state imaging element is provided with pixels formed on a semiconductor substrate; a photoelectric conversion section arranged in the pixel for converting light into an electric signal; and a microlens arranged above the photoelectric conversion section. The microlens has a flat plane shape wherein linear distances from the center to the lens end are different. The microlens has n number of first bottom portions (n is a natural number) wherein the linear distances are relatively long in the vicinity of lens end, and second bottom portions not including the first bottom portions. The height in the vertical direction from the upper plane of the photoelectric conversion section is less at the first bottom portion than that at the second bottom portion. Thus, light is efficiently focused on the photoelectric conversion section. ® KIPO & WIPO 2008
    • 固态成像元件设置有形成在半导体衬底上的像素; 光电转换部,配置在像素中,用于将光转换为电信号; 以及布置在光电转换部上方的微透镜。 微透镜具有平面形状,其中从中心到透镜端的线性距离不同。 微透镜具有n个第一底部(n是自然数),其中在透镜端附近的线性距离相对较长,而第二底部不包括第一底部。 在光电转换部的上面的垂直方向上的高度比第一底部的高度低于第二底部。 因此,光被有效地集中在光电转换部上。 ®KIPO&WIPO 2008
