Title:
SOLID-STATE IMAGE PICKUP DEVICE
Document Type and Number:
WIPO Patent Application WO/2014/061100
Kind Code:
A1
Abstract:
In this solid-state image pickup device, N regions (6a, 6b, 6c) to be photoelectric conversion diodes are formed at the outer circumference portions of P regions (3a, 3b, 3c) of upper portions in island-like semiconductor sections (H1, H2, H3) formed on a substrate (1), and P+ regions (7a, 7b, 7c) to be connected to pixel selection line conductor layers (8) are formed on surface layer portions of upper end portions of the island-like semiconductor sections (H1, H2, H3) such that the P+ regions are in contact with N regions (6a, 6b, 6c) and P regions (3a, 3b, 3c). The thickness of the P+ region (7a) is less than that of the P+ region (7b), and the thickness of the P+ region (7b) is less than that of the P+ region (7c).
