Abstract:
An optical semiconductor package comprising:an electrical connection support plate having 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 semiconductor component from the support plate; encapsulation means comprising 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 means located on an exposed part of the support plate.
