Abstract
In a solid-state image pick-up device 10 in which a microlens layer 16 is provided on a surface of a semiconductor substrate 11 having photoelectric converting units 12H and 12L for storing an electric charge corresponding to an amount of incident light arranged vertically and horizontally, a microlens 16H to be provided on the microlens layer 16 is disposed on only the photoelectric converting unit 12H to be used as a pixel having a high sensitivity and the microlens layer 16 in a position facing the photoelectric converting unit 12L to be used as a residual pixel having a low sensitivity has a planar structure 16L or a perforated structure 16L.
Claims5
A solid-state image pick-up device in which a microlens layer is provided on a surface side of a semiconductor substrate having photoelectric converting units for storing an electric charge corresponding to an amount of incident light, being arranged vertically and horizontally, wherein a microlens to be provided on the microlens layer is disposed above only the photoelectric converting unit to be used as a pixel of a high sensitivity, while the microlens layer in a position facing the photoelectric converting unit to be used as a residual pixel of a low sensitivity has a planar or perforated structure.
