US 2003/0075488 A1 · Method and apparatus for sorting semiconductor devices

Abstract

A method and apparatus is provided for sorting semiconductor devices for processing where the semiconductor devices have been singulated from a strip containing a plurality of semiconductor devices and where an electronic strip map has been created corresponding to the strip of semiconductor devices and the electronic strip map contains address and quality information related to each individual singulated semiconductor device. The method includes the steps of moving a pickup device to a location adjacent the singulated semiconductor devices and selectively picking up a first plurality of singulated semiconductor devices based on the electronic strip map information related to the singulated semiconductor devices and moving the semiconductor devices that have been picked up to a predetermined location based on the electronic strip map information related to the specific semiconductor devices that have been picked up and unloading the first plurality of semiconductor devices at the predetermined location.
