A sensor-in-package device, a process for fabricating a hermetically-sealed sensor-in-package device, and a process for fabricating a hermetically-sealed sensor-in-package device with a pre-assembled hat that employ example techniques in accordance with the present disclosure are described herein. In an implementation, the sensor-in-package device includes a substrate; at least one thermopile, at least one photodetector, at least one light-emitting diode, an ultraviolet light sensor, and a pre-assembled hat disposed on the first side of the substrate, where the pre-assembled hat includes a body; a first lid; and a second lid; where the body, the substrate, and the first lid define a thermopile cavity that houses the at least one thermopile, and where the body, the substrate, and the second lid define an optical cavity that houses at least one of the at least one photodetector, the at least one light-emitting diode, or the ultraviolet light sensor.

Hermetic solution for thermal and optical sensor-in-package

Embodiments of the present invention include a method for multi-chip packaging. For example, the method includes positioning a first integrated circuit (IC) on a substrate package based on a first set of reference markers in physical contact with the substrate package and confirming an alignment of the first IC based on a second set of reference markers in physical contact with the substrate package. A second IC is stacked onto first IC based on the first set of reference markers. An alignment of the second IC is confirmed based on the second set of reference markers, where the second set of reference markers is disposed at a different location on the substrate package than the first set of reference markers.

Method of chip positioning for multi-chip packaging

An optical sensor device, system, and method are described that include a substrate, an electronic device disposed on the substrate, a molding layer, a lens, and a light-emitting diode (LED) package disposed on the substrate and at least partially over the sensor and molding layer. The LED package can include an LED substrate, an LED, a lens disposed on the LED, and electrical interconnections for coupling the LED to the substrate. In implementations, a process for fabricating the optical sensor device includes backgrinding a sensor die to a slim profile; attaching the sensor die onto a substrate; placing a molding layer on the sensor die; forming a lens on the molding layer; and placing an assembled light-emitting diode package on the substrate and at least partially over the sensor die and molding layer, where the assembled light-emitting diode package includes a 3D substrate.

Stacked LED for optical sensor devices

Embodiments of the present invention include a substrate package, a method for multi-chip packaging, and a multi-chip package. For example, the substrate package includes a first set of reference markers and a second set of reference markers. The first set of reference markers is disposed on the substrate package, where the first set of reference markers is configured to provide a first alignment for positioning a first integrated circuit (IC) and a second alignment for positioning a second IC on the substrate package. Further, the second set of reference markers is disposed at a different location on the substrate package than the first set of reference markers, where the second set of reference markers is configured to provide confirmation of the first alignment and the second alignment.
