Abstract
Optical semiconductor package and process for fabricating an optical semiconductor package, in which an electrical connection support plate ( ) has a through-passage ( ); a first semiconductor component ( ) such as a microprocessor placed behind the support plate and lying opposite the through-passage; electrical connection metal balls ( ) inserted into the annular space separating the first component from the support plate; encapsulation mechanism including an encapsulation material ( ) lying in the annular space; a second semiconductor component ( ), a front face ( ) of which has an optical sensor and a rear face of which is fixed to the front face ( ) of the first component ( ) through the through-passage ( ) of the support plate ( ); metal electrical connection wires ( ) connecting the front face of the second component and the front face of the support plate; a front encapsulation lid ( ) which covers the through-passage and the metal wires at some distance and which has at least one transparent part ( ) lying in front of the optical sensor, and external electrical connection ( ) located on an exposed part of the support plate.
