This application claims priority to U.S. Provisional Application No. 62/302227, filed on Mar. 2, 2016, entitled “High Reliability Housing for a Semiconductor Package,” invented by Yu-Te Hsieh, and is incorporated herein by reference and priority thereto for common subject matter is hereby claimed.
BACKGROUND Technical FieldAspects of this document relate generally to semiconductor packages with dies having sensing areas. More specific implementations involve chip on board packages with image sensors.
Background ArtConventionally, to seal a semiconductor package, liquid encapsulation (LE) or molding is used. The LE covers and protects the connectors from mechanical damage and protects the area where the glass lid and die are coupled together from moisture.
SUMMARYImplementations of semiconductor packages may include: a substrate coupled to one or more die and to one or more connectors, a glass lid coupled over one or more die by an adhesive and a housing comprising one or more sides and a bottom opening and a top opening. The substrate may be coupled to the housing at the bottom opening and the glass lid may be coupled under the housing at the top opening.
Implementations of semiconductor packages may include one, all, or any of the following:
The substrate may be a ball grid array substrate.
The one or more die may be stacked on each other.
A mold compound may encapsulate at least a portion of one of the one or more die or at least one of the one or more connectors.
The housing may be made of an opaque material.
The housing may be formed through injection molding, transfer molding or any combination thereof.
A plurality of ball mounts may be coupled to a second side of the substrate opposing a side of the substrate coupled to the die.
The one or more lenses may be coupled to the housing in an optical path of the glass lid.
Implementations of semiconductor packages may be manufactured using implementations of a method of making a semiconductor package. The method may include providing a substrate and coupling one or more die to the substrate. The method may also include electrically coupling the die to the substrate using one or more connectors. The method may also include coupling a glass lid to the one or more die using an adhesive. The method may also include simultaneously coupling a housing to the substrate at a bottom opening of the housing and over a glass lid at a top opening of the housing using an adhesive.
Implementations of a method of making a semiconductor package may include one, all or any of the following:

A plurality of ball mounts may be coupled to a second side of the substrate opposing a side of the substrate coupled to the die.
One or more lenses may be coupled to the housing in an optical path of the glass lid.
Semiconductor package implementations disclosed herein may be manufactured using another implementation of a method of manufacturing a semiconductor package. The method may include providing a substrate, coupling one or more die to the substrate and electrically coupling the die to the substrate using one or more connectors. The method may also include encapsulating one or more connectors and at least a portion of one of the one or more die using a mold compound. The method may also include coupling an additional die to one of the one or more die. The method may also include electrically coupling the additional die to the substrate with one or more connectors. The method may also include coupling a glass lid to the additional die using an adhesive. The method may also include simultaneously coupling a housing to the substrate at a bottom opening of the housing and over the glass lid at a top of the housing using an adhesive.
