Patent number: 9496298Abstract: A first semiconductor substrate 1 and a second semiconductor substrate 2 are different in material, and therefore have sensitivities to incident light of mutually different wavelength bands. Respective photodiodes of photodiode arrays are connected to amplifiers of the first semiconductor substrate 1. According to this method, the second semiconductor substrate 2 is separated from the wafer by etching the second semiconductor substrate 2 and then dicing a deepest portion of the etched groove. The density of crystal defects in a side surface produced by etching is smaller than the density of crystal defects in a side surface produced by dicing. Because a photodiode located in an end portion of the second semiconductor substrate 2 does not need to be removed, a reduction in the number of photodiodes can be suppressed.Type: GrantFiled: March 27, 2012Date of Patent: November 15, 2016Assignee: HAMAMATSU PHOTONICS K.K.Inventors: Masatoshi Ishihara, Nao Inoue, Hirokazu Yamamoto
