Computer-controlled individual chip management system for processing wafers

A chip-managing system for managing production of wafers on each of which a plurality of chips requiring different kinds of processing information are mounted, said chip-managing system comprising:

• a first terminal for receiving lot information, device information, processing information, and chip position information;
• a line terminal for receiving production line interior information;
• a processing apparatus for processing chips in a lot;
• a host computer, to which said first terminal and said line terminal are connected, for creating information concerning a processing of each individual chip from said lot information entered into said host computer and supplying the created information to said processing apparatus;
• a processing information storage means connected to said host computer and serving to receive the processing information input from said first terminal via said host computer and to store said processing information;
• a line interior information storage means connected to said host computer and serving to receive line interior information input from said line terminal via said host computer and to store said line interior information;
• a chip-managing computer connected to said host computer and serving to create maps of the chips on said wafers from said lot information, said device information and said chip position information and to number said chips so as to correlate the device information with respective chip numbers, for creating map information;
• and
• a chip information storage means connected to said chip-managing computer and serving to store said map information.
