Patent ID: 7563644

Claim:
A method for fabricating an optical device, comprising steps in an order of: (a) of molding a lead frame with a wiring pattern to form a molded structure of bases with a plurality of optical device formation regions each surrounded by respective opening; (b) attaching, after the step (a), an optical element chip to each of the optical device formation regions so that the chip partially covers the opening, the optical device formation regions being located in the molded structure of the bases or in individual separated parts made by splitting the molded structure; (c) partially sealing, after the step (b), the optical element chips and connecting portions of the molded structure or of the separated parts of the molded structure respectively with a first resin member; (d) attaching, translucent members to the molded structure or the separated parts of the molded structure respectively so that each of the translucent members faces the corresponding optical element chip with the opening interposed therebetween; and (e) sealing, the translucent members and the molded structure of the bases or the separated parts with a second resin member, wherein in the step (a), a resin sealing is carried out with an internal terminal portion of the wiring pattern put on a projection of a lower die of molding dies and thereby sandwiched by an upper die and the lower die.
