Optical device and method for fabricating the same

摘要

An optical device includes: a base 10 ; an optical element chip 5 mounted on the base 10 ; an integrated circuit chip 50 bonded to the back surface of the optical element chip 5 ; and a transparent member (window member 6 ). An interconnect 12 is buried in the base 10 . The interconnect 12 has an inner terminal portion 12 a, an outer terminal portion 12 b and an intermediate terminal portion 12 c. Pad electrodes 5 b on the optical element chip 5 are connected to the inner terminal portion 12 a via bumps 8 . Pad electrodes 50 b on the integrated circuit chip 50 are connected to the intermediate terminal portion 12 c via fine metal wires 52 . The integrated circuit chip 50 equipped with peripheral circuits and other circuits and the optical element chip 5 are combined into one package.
