An electronic package includes a substrate wafer having front and rear faces. An emitting integrated circuit chip is mounted to the front face of the substrate wafer and includes a light radiation optical emitter. A receiving integrated circuit chip is also mounted to the front face of the substrate wafer and includes at least one light radiation optical sensor. A transparent encapsulant extends above the optical sensor and the optical emitter. An opaque encapsulant encapsulates the transparent encapsulant. The opaque encapsulant has a front window situated above the optical emitter and which is offset laterally relative to the optical sensor. The transparent encapsulant accordingly has an uncovered front face situated above the optical emitter and offset laterally relative to the optical sensor. The opaque encapsulant may include an additional front window. The receiving integrated circuit chip further includes a second optical sensor situated opposite the additional front window.

A semiconductor component, semiconductor wafer and semiconductor package include an integrated-circuit chip having, on a front face, an optical sensor and electrical connection pads between the edge of this face and this optical sensor. A protective patch made of a transparent material is placed in front of the optical sensor but does not cover the said optical connection pads. The said protective patch is fixed to the front face of the said chip by a bead of an adhesive extending annularly between, and at a certain distance from, the edge of the said optical sensor and of the electrical connection pads. At least one of the faces of the patch is covered with a protective layer of a material that filters out infrared light rays.
