PROBLEM TO BE SOLVED: To control the film thickness of an on-chip micro lens in proportion to the area of a unit pixel, to make a process control easy and to improve optical transparent efficiency. SOLUTION: Four convex lens sections 50A, 50B, 50C and 50D of the on-chip micro lens 50 are placed corresponding to a unit pixel 20. A reading gate 38 and a FD section 24 of a reading transistor M2 are arranged in a central part of a light receiving section 22A of a photo diode 22, with them isolated. A control wire 40 of the reading gate 38 and a wire 42 of the FD section 24 are placed by using boundaries of convex lens sections 50A, 50B, 50C and 50D of the on-chip micro lens 50. Other wire such as a wire 44 and a light blocking band wire 46 can be also placed in the boundaries. COPYRIGHT: (C)2003,JPO
