Abstract:
A semiconductor device has a substrate containing a transparent or translucent material. A spacer is mounted to the substrate. A first semiconductor die has an active region and first conductive vias electrically connected to the active region. The active region can include a sensor responsive to light received through the substrate. The first die is mounted to the spacer with the active region positioned over an opening in the spacer and oriented toward the substrate. An encapsulant is deposited over the first die and substrate. An interconnect structure is formed over the encapsulant and first die. The interconnect structure is electrically connected through the first conductive vias to the active region. A second semiconductor die having second conductive vias can be mounted to the first die with the first conductive vias electrically connected to the second conductive vias.
Abstract:
A semiconductor device has a semiconductor die and conductive layer formed over a surface of the semiconductor die. A first channel can be formed in the semiconductor die. An encapsulant is deposited over the semiconductor die. A second channel can be formed in the encapsulant. A first insulating layer is formed over the semiconductor die and first conductive layer and into the first channel. The first insulating layer extends into the second channel. The first insulating layer has characteristics of tensile strength greater than 150 MPa, elongation between 35-150%, and thickness of 2-30 micrometers. A second insulating layer can be formed over the semiconductor die prior to forming the first insulating layer. An interconnect structure is formed over the semiconductor die and encapsulant. The interconnect structure is electrically connected to the first conductive layer. The first insulating layer provides stress relief during formation of the interconnect structure.
Abstract:
A semiconductor device is made by forming an interconnect structure over a substrate. A semiconductor die is mounted to the interconnect structure. The semiconductor die is electrically connected to the interconnect structure. A ground pad is formed over the interconnect structure. An encapsulant is formed over the semiconductor die and interconnect structure. A shielding cage can be formed over the semiconductor die prior to forming the encapsulant. A shielding layer is formed over the encapsulant after forming the interconnect structure to isolate the semiconductor die with respect to inter-device interference. The shielding layer conforms to a geometry of the encapsulant and electrically connects to the ground pad. The shielding layer can be electrically connected to ground through a conductive pillar. A backside interconnect structure is formed over the interconnect structure, opposite the semiconductor die.

Abstract:
A semiconductor package is made using a prefabricated post carrier including a base plate and plurality of conductive posts. A film encapsulant is disposed over the base plate of the post carrier and around the conductive posts. A semiconductor die is mounted to a temporary carrier. The post carrier and temporary carrier are pressed together to embed the semiconductor die in the film encapsulant. The semiconductor die is disposed between the conductive posts in the film encapsulant. The temporary carrier and base plate of the post carrier are removed. A first circuit build-up layer is formed over a first side of the film encapsulant. The first circuit build-up layer is electrically connected to the conductive posts. A second circuit build-up layer is formed over a second side of the film encapsulant opposite the first side. The second circuit build-up layer is electrically connected to the conductive posts.
