Abstract:
1. A physical-quantity detection device comprising: at least first and second semiconductor substrates secured together in a stacked relationship, the first semiconductor substrate including a pixel-array section in which pixels are arranged in a two-dimensional matrix having rows and columns, wherein, said pixels in said pixel array generate pixel signals, each of the first and second semiconductor substrates has a plurality of terminals arranged along the same direction near a first edge of the substrate, the terminals of the first and second substrates have the same pitch, the terminals of the first and second substrates extend in the same direction as a row direction of the pixel-array section, the terminals are positioned in registry with each other, the terminals are alternately staggered along the column direction, the terminals of the first and second substrates are connected to each other by bump electrodes, a plurality of dummy electrodes positioned between the first and second substrates along a second edge opposite the first edge in a manner to effectively maintain an even spacing between the first and second substrates, each column of the pixel array has a corresponding terminal on the first substrate, each terminal of the first substrate is connected in parallel to a corresponding one terminal of the second substrate, the first semiconductor substrate transmits a pixel signal to the second semiconductor substrate in parallel through the terminals, and the second semiconductor substrate includes circuitry configured to scan the transmitted pixel signal to input the signal into a next stage circuit.
