Semiconductor package comprising an optical semiconductor device

摘要

A semiconductor package includes a transmissive support plate and includes at least one elongate hole. An integrated circuit semiconductor device is mounted on a rear face of the support plate. The semiconductor device includes first and second optical elements oriented towards the rear face of the support plate, where the first and second optical elements are placed on either side of the elongate hole. An encapsulation material made of an opaque material encapsulates the semiconductor device and fills the elongate hole so as to form an optical insulation partition between the first and second optical elements. A cavity is left, however, between each optical element and a rear face of the support plate.

1. A semiconductor package, comprising:
a support plate made of a light radiation transmissive material and having at least one elongate hole open at least on a rear face of this support plate, an integrated circuit semiconductor device mounted on the rear face of said support plate and having at least two optical elements facing the rear face of said support plate, the integrated circuit semiconductor device passing above the elongate hole and at least one of the at least two optical elements being placed on each side of said elongate hole, and an encapsulation block made of a single-composition opaque material encapsulating the semiconductor device on said support plate at least by enveloping the periphery of the integrated circuit semiconductor device and filling said elongate hole to form an optical insulation partition between said optical elements and leaving empty cavities remaining between the optical elements and the support plate.
