Abstract

It is an object to provide a technique capable of providing a semiconductor device with information indicating a plurality of electrical characteristics. A semiconductor device sorting system includes a characteristic measurement unit measuring electrical characteristics of a semiconductor device, a rank determination database for classifying the electrical characteristics into ranks, a calculation unit classifying the plurality of electrical characteristics of the semiconductor device measured by the characteristic measurement unit into a plurality of ranks with reference to the rank determination database, a writing unit converting the plurality of ranks classified by the calculation unit into a graphic symbolic code and forming the graphic symbolic code on the semiconductor device, a reading unit reading the plurality of ranks from the graphic symbolic code formed on the semiconductor device, and a sorting unit sorting the semiconductor device based on the plurality of ranks being read by the reading unit.
