Patent ID: 8375340

Claim:
A test substrate manufacturing apparatus for manufacturing a test substrate on which are formed a plurality of test circuits that test a plurality of devices under test formed on a wafer under test, the test substrate manufacturing apparatus comprising: a test circuit database that stores circuit data of the plurality of test circuits in association with a plurality of types of testing content; a definition information storing section that stores definition information defining arrangements of device pads of the devices under test and testing content to be performed for each of the device pads; and a lithography data generating section that generates lithography data for the test substrate by (i) selecting, from the test circuit database, circuit data of each test circuit to be connected to a device pad based on the testing content defined by the definition information stored in the definition information storing section and (ii) determining positions on the test substrate where the test circuits corresponding to the selected circuit data are formed using lithography, based on the arrangements of the device pads as defined by the definition information, wherein the test substrate includes a plurality of individual regions corresponding to the devices under test, circuit blocks are formed in the individual regions, each of the circuit blocks including: a plurality of the test circuits; and a plurality of test pads formed at positions corresponding to the device pads of a corresponding device under test.
