Abstract
A method for making an optical proximity sensor includes forming a package top plate having an optical transmit opening and an optical receive opening extending therethrough, attaching an optical transmit element to the package top plate adjacent the optical transmit opening, and attaching an optical receive element to the package top plate adjacent the optical receive opening. A package body is formed onto the package top plate to define an optical transmit cavity receiving the optical transmit element and an optical receive cavity receiving the optical receive element.
