Patent ID: 8193558

Claim:
An optical electronic component manufactured using a method employing a die, the die including a first piece, a second piece having cavities and being arranged opposite to said first piece, and a third piece arranged between said first and second pieces, and a mold release film covering said cavities to seal and mold an optical device in each of said cavities with resin, comprising: attaching to said first piece a substrate having the optical devices mounted thereon; bringing said mold release film which is sandwiched between said second and third pieces into contact with each surface of said cavities along a geometry of said cavities; closing said first, second and third pieces together and sealing said optical devices in said cavities with melted resin or resin in a form of liquid; setting said melted resin or said resin in the form of liquid to result in a transparent set resin; separating said first, second and third pieces; removing from said first piece said substrate having said optical devices sealed in said transparent set resin; and forming optical electronic components by cutting said substrate having said optical devices sealed in said transparent set resin, wherein each of said cavities has a curved portion corresponding to each of said optical devices, and a flat portion allowing the curved portions to communicate with each other to allow the melted resin or the resin in the form of liquid to flow from one curved portion to another.
