Proximity sensor having electro-less plated shielding structure

A proximity sensor comprising:

• a substrate panel 10 having an emitter region and a receiver region;
• an emitter unit 20 disposed on the emitter region of the substrate panel and configured to emit electromagnetic signals at a particular wavelength;
• a receiver unit 30 disposed on the receiver region of the substrate panel and configured to respond to electromagnetic signals emitted by the emitter unit;
• a transparent molding unit 40 disposed on the emitter region and the receiver region of the substrate panel 10 for covering the emitter unit 20 and the receiver unit 30, the transparent molding unit 40 being transparent to electromagnetic waves generated by the emitter unit;
• and
• an optical shielding layer selectively disposed on the external surfaces of the substrate panel and the transparent molding unit, the shielding layer having an emitter window formed in correspondence to the emitter unit and a receiver window formed in correspondence to the receiver unit,
• wherein the emitter window and the receiver window are correspondingly arranged toward a designated detection region.
