US 2009/0267899 A1 · OPTICAL SENSOR MODULE FOR OPTICAL POINTING DEVICE AND METHOD OF FABRICATING THE SAME

Abstract

An optical sensor module for an optical pointing device and a method of fabricating the same are provided. The optical sensor includes: a lead frame having a light receiving hole formed in a pad; an image sensor attached to the pad and detecting light emitted from a light source through the light receiving hole; and a molding member for integrally molding the lead frame and the image sensor. The method includes: forming a light receiving hole in a pad of a lead frame; attaching an image sensor to the pad; connecting the image sensor to a lead of the lead frame by bonding using a wire; molding the lead frame and the image sensor; and trimming the lead of the lead frame to a certain length and forming the lead.
