Abstract
There is provided a hybrid mounted device that includes a element such as semiconductor laser diode (LD), and a board such as a silicon platform having formed thereon an optical waveguide. The LD is mounted to the silicon platform, and is optically coupled to the optical waveguide. The mounting position of the LD is determined by positioning first alignment marks formed on the board and second alignment marks formed on the LD. In this configuration, initial positional deviation amount measuring marks that can measure the initial positional deviation amount of the first alignment marks themselves are formed on the board. The mounting position of the is corrected to a position where the second alignment marks are shifted with respect to the first alignment marks according to the initial positional deviation amount measured from the initial positional deviation amount measuring marks.
