Solid-state image pickup device using layers having different refractive indices

A solid-state image pickup apparatus comprising:

• a plurality of pixels, each pixel comprising a photoelectric conversion element including a first area of a first conductivity type and a second area which is formed in the first area and has a second conductivity type opposite to the first conductivity type, an amplifier transistor for amplifying and outputting a signal output from said photoelectric conversion element, and a reset transistor for resetting a control electrode of the amplifier transistor;
• an output line for outputting a signal from said each pixel;
• a reset signal line for supplying a predetermined signal to a control electrode of said each reset transistor;
• and
• a concave upper surface portion positioned over said each second area;
• wherein said concave upper surface portion is positioned on steps of at least intersecting two of said output line, a power supply line, a select line and said reset signal line, and wherein no leveling layer exists in an area which is located in a vertical direction between said concave upper surface portion and said output line, said power supply line, said select line and said reset signal line.
