Abstract
Official abstract text for this publication.
This photodiode array module includes a first semiconductor substrate 2 having a first photodiode array that is sensitive to light of a first wavelength band, a second semiconductor substrate 2 ′ having a second photodiode array that is sensitive to light of a second wavelength band, and a third semiconductor substrate 3 which is formed with a plurality of amplifiers AMP and on which the first and second semiconductor substrates 2, 2 ′ 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 substrate 2 and the second semiconductor substrate 2 ′, stepped portions are formed, which thus allows performing measurement with low noise even when respective pixels are aligned successively over both substrates.
