摘要: A photodiode has integrated shields for the rejection of noise-producing electromagnetic interference and ambient light. The electromagnetic shield forms a conductive matrix which covers the photodiode active area. The matrix is deposited as a metallization layer onto the photodiode and provides exposed portions of the active area for light detection. A pad is electrically connected to the shield to allow external termination of the shield. The ambient-light shield is in the form of a colored encapsulant surrounding the photodiode. The encapsulant provides a high-pass light transmission characteristic which passes signal light and rejects out-of-band ambient light. The photodiode is particularly advantageous for use in pulse oximetry probes.

摘要: An optoelectronic component has a lens that is formed in the surface of an encapsulant surrounding a semiconductor diode element. With respect to emitters, the lens reduces internal reflection and reduces dispersion to increase overall efficiency. With respect to detectors, the lens focuses photons on the active area of the detector, increasing detector sensitivity, which allows a detector having a reduced size and reduced cost for a given application. The lens portion of the encapsulant is generally nonprotruding from the surrounding portions of the encapsulant reducing contact surface pressure caused by the optoelectronic component. This non-protruding lens is particularly useful in pulse oximetry sensor applications. The lens is advantageously formed with a contoured-tip ejector pin incorporated into the encapsulant transfer mold, and the lens shape facilitates mold release.
