摘要： PROBLEM TO BE SOLVED: To provide a photoelectric conversion module which can perform big packaging of the same alignment tolerance as an electric packaging precision in a regular multi chip module when a photoelectric conversion element and an electronic circuit element are packaged and which is excellent in radio frequency characteristics.
SOLUTION: When the photoelectric conversion element 3 and the electronic circuit element 7 are packaged and the photoelectric conversion module 1 is manufactured, the photoelectric conversion element 3 is optically mounted beforehand as the first package 6 of the optical element 4. Thereby, in sealing of the multi chip module, optical packaging at the time of formation of the photoelectric element module 1 becomes unnecessary by the same sealing as the regular electricity packaging package, and it can be manufactured simply with a low cost. Further, the photoelectric conversion element 3 is formed on one side of the semiconductor substrate 2. Since the photoelectric conversion element 3 is mounted only by flip chip packaging between the substrates 2 and 9 and wire bond packaging is used, its radio frequency characteristics can also be improved.
