1. A method of fabricating a camera module comprising:
- placing a window in a cavity of a first mold half;
moving a second mold half into a closed position on the first mold half, wherein the second mold half comprises an extension comprising a base, the base of the second mold half pressing against an interior surface of the window;
filling a space around the window and between the first mold half and the second mold half with a molding compound to form a lens mount enclosing the window;
removing the lens mount and window from the first mold half and the second mold half;
coupling an image sensor to a substrate; and
coupling the lens mount to the substrate around the image sensor.

Abstract
An image sensor package includes an image sensor, a window, and a molding, where the molding includes a lens holder extension portion extending upwards from the window. The lens holder extension portion includes a female threaded aperture extending from the window such that the window is exposed through the aperture. A lens is supported in a threaded lens support. The threaded lens support is threaded into the aperture of the lens holder extension portion. The lens is readily adjusted relative to the image sensor by rotating the lens support.

19. A method of fabricating an image sensor package comprising:
-
placing a window in a cavity of a first mold half, the first mold half comprising a compliant pad; moving a second mold half into a closed position on the first mold half, wherein the second mold half comprises a compliant pad, the compliant pad of the second mold half pressing against a central region of an interior surface of the window, the complaint pad of the first mold half pressing against a central region of an exterior surface of the window; filling a space around the window and between the first mold half and the second mold half with a molding compound to form a molding enclosing the window, the filling comprising; filling a space between the first mold half and a peripheral region of the exterior surface of the window; and filling a space between the second mold half and a peripheral region of the interior surface of the window; removing the molding and window from the first mold half and the second mold half; coupling an image sensor to a substrate; and coupling the molding to the substrate around the image sensor.
