Inventor: FURUTA TATSUHIKO
IPC: H04N5/372
Filed: 1999-03-12
Abstract: PROBLEM TO BE SOLVED: To improve the sensitivity of a solid-state image pickup element by preventing the occurrence of lens welding and effectively utilizing the light beams made incident to inter-lens gap areas. SOLUTION: A solid-stage image pickup element has a flattened layer 2, provided with a groove section 13 surrounding each light receiving section on a substrate, on which a plurality of light receiving sections is formed and convex lenses 1 outside the groove section 13 of the flattened layer 2 and concave lenses 15 inside the groove section 13.
