Patent ID: 7079960

Claim:
A method for sorting semiconductor devices in support of an Automatic Classification Shipping function, comprising the steps of: entering user requirements into a supporting data base storage; entering wafer and chip logistics data into the supporting data base storage, said logistics data being required for control of wafer and chip product flow; entering a chip testing data into the supporting data base storage, thereby including test criteria, said test criteria being divided into a range of acceptable test result values, said range of acceptable test result values having a high limit value and a low limit value, said chip test criteria further comprising a biasing parameter; positioning said chip in a chip tester device to perform at least one test on said chip, thereby obtaining a test result; calculating at least one weight point for said at least one test, said calculation being based on comparing said test result with said high limit value or said low limit value; providing at least two chip classes; dividing said at least one chip class into at least one multiple chip class.
