Embedded image sensor semiconductor packages and related methods
View Patent ↗An embedded image sensor package including a transparent cover having a first side and an opposing second side. A first layer couples over the second side of the transparent cover and has an opening. An electrically conductive layer couples in or over the first layer and electrically couples with one or more electrical contacts exposed on an outer surface of the package. An image sensor chip having a first side with an image sensor and an opposing second side electrically couples with the electrically conductive layer at the first side of the image sensor chip. The image sensor chip couples over the first layer so the first side of the image sensor chip faces the second side of the transparent cover through the opening. The image sensor chip, first layer, and transparent cover at least partially define a cavity hermetically sealed using an underfill material. The package includes no wirebonds.
