Image sensor package fabrication method
View Patent ↗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.
1. A method comprising:
coupling an image sensor to a first surface of a substrate;
coupling a molding to said substrate;

coupling said lens support to said molding; and
forming interconnection balls on a second surface of said substrate.
2. The method of claim 1 further comprising coupling bond pads of said image sensor to traces of said substrate.
3. The method of claim 2 wherein said coupling bond pads comprises forming bond wires between said bond pads and said traces.
4. The method of claim 1 wherein said coupling a molding to said substrate comprises applying an adhesive layer to a base of said molding.
5. The method of claim 4 wherein said applying comprises dispensing said adhesive layer.
6. The method of claim 4 wherein said applying comprises screen printing said adhesive layer.
7. The method of claim 4 wherein said applying comprise pressing said adhesive layer.
8. The method of claim 1 wherein said coupling a molding to said substrate comprises applying an adhesive layer to a periphery of said first surface of said substrate.
9. The method of claim 1 wherein said coupling a molding to said substrate comprises aligning said molding to said substrate using one or more alignment notches of said molding.
10. A method comprising:
coupling a first image sensor to a first substrate;
coupling a second image sensor to a second substrate, said second substrate being integrally connected to said first substrate;

15. The method of claim 14 wherein said bridge section has a narrow portion and a wide portion, said narrow portion having less width than said wide portion.
16. The method of claim 15 wherein said narrow portion has less mechanical strength than said wide portion.
17. The method of claim 15 wherein said snapping said bridge section comprises snapping said narrow portion.
18. The method of claim 10 wherein said bridge portion comprises:
a first body portion;
a second body portion; and
a finger portion extending between said first body portion and said second body portion.
19. A method comprising:
coupling an image sensor to a first surface of a substrate;
coupling a molding to said substrate;
coupling an optical element to a lens support;
coupling said lens support to said molding; and
coupling an interconnection structure on a second surface of said substrate to a larger substrate.
