Abstract: Various embodiments of an integrated circuit package and a method of forming such package are disclosed. The package includes a substrate having a core layer disposed between a first dielectric layer and a second dielectric layer, a die disposed in a cavity of the core layer, and an encapsulant disposed in the cavity between the die and a sidewall of the cavity. The package further includes a first patterned conductive layer disposed within the first dielectric layer, a device disposed on an outer surface of the first dielectric layer such that the first patterned conductive layer is between the device and the core layer, a second patterned conductive layer disposed within the second dielectric layer, and a conductive pad disposed on an outer surface of the second dielectric layer such that the second patterned conductive layer is between the conductive pad and the core layer.

Abstract: Various embodiments of a sealed package and a method of forming such package are disclosed. The package includes a housing, a substrate hermetically sealed to the housing, and a light source disposed on a first major surface of the substrate. The package further includes a detector disposed on the first major surface of the substrate and having a detecting surface. The package also includes a masking layer disposed on at least one of the first major surface and a second major surface of the substrate, where the masking layer includes a first aperture aligned with an emission axis of the light source in a direction orthogonal to the first major surface of the substrate. The masking layer further includes a second aperture aligned with a detection axis of the detector in a direction orthogonal to the first major surface of the substrate.
