Abstract:
A system for cutting and sorting automation, comprising:a loader for receiving a first cassette storing a substrate from a stocker or other equipment, and for holding the first cassette; a cutter for cutting the substrate into a plurality of cut substrates of predetermined sizes after receiving the substrate in the first cassette from said loader; a substrate identifier reader for reading an identifier of each cut substrate received from said cutter; an unloader for sorting and storing the plurality of cut substrates to a second cassette placed on a cassette storing station according to a read result of each cut substrate and a predetermined operating mode after receiving the plurality of cut substrates from said substrate identifier reader; and a system controller for receiving a request for operation information on each cut substrate from said unloader, and transmitting the operation information and operation commands to said unloader, wherein when the substrate has a defective cell, said unloader performs the predetermined operating mode to sort the plurality of cut substrates, said predetermined operating mode selected from a plurality of predetermined operating modes comprising: (a) a sequence mode in which each cut substrate is supplied in sequence to the second cassette, (b) a position mode in which each cut substrate is supplied to the second cassette according to a position where each cut substrate was cut from the substrate, and (c) a grade mode in which each cut substrate is supplied to the second cassette according to a predetermined defect grade of each cut substrate.
