Abstract
This photodiode array module includes a first semiconductor substratehaving a first photodiode array that is sensitive to light of a first wavelength band, a second semiconductor substrate' having a second photodiode array that is sensitive to light of a second wavelength band, and a third semiconductor substratewhich is formed with a plurality of amplifiers AMP and on which the first and second semiconductor substrates′ are placed side by side without overlapping, and which connects each photodiode to the amplifier AMP via a bump. In adjacent end portions of the first semiconductor substrateand the second semiconductor substrate′, stepped portions are formed, which thus allows performing measurement with low noise even when respective pixels are aligned successively over both substrates.
