Abstract: An image sensor package includes an image sensor having an active area, a window, and a window support in contact with the active area and in contact with the window. The window support entirely encloses, and thus protects, the active area of the image sensor. During use, radiation passes through the window, passes through the window support, and strikes the active area, which responds to the radiation. By forming the window and the window support to have a similar refractive index, the amount of reflected radiation is minimized thus enhancing the sensitivity of the image sensor package. Further, the window support completely fills the region between the window and the active area thus eliminating any possibility of moisture condensation within the image sensor package.
