Abstract
A packaging structure suitable for an integrated circuit device receiving short-wavelength laser light is provided. The integrated circuit device having a photo detecting part, leads and wires for connection therebetween are encapsulated in an encapsulation section. A recess is formed on the light incident surface of the encapsulation section above the photo detecting part, to thin the encapsulation section on the surface of the photo detecting part and thereby reduce the energy of light absorbed by the encapsulation section.
