Abstract
Abstract An image sensor package includes an image sensor having bond pads and an active area on an upper surface of the image sensor. The image sensor package further includes a window support on the upper surface of the image sensor. The window support entirely encloses the upper surface including the active area and the bond pads. A window is in contact with the window support, the window overlying the active area. Generally, the window support and the window entirely enclose, and thus protect, the active area of the image sensor.
