Device for testing semiconductor integrated circuits and method of testing the same

摘要

Tests of a semiconductor IC is conducted first by bringing a plurality of conductive pattern circuits formed on an insulator sheet into contact with a plurality of bump electrodes formed on a substrate of the semiconductor, second by connecting a plurality of signal transmission pattern circuits formed on a transmission circuit substrate with each conductive pattern circuit of the insulator sheet, and then by connecting the transmission circuit substrate with a body of the testing device. A probing test can be simplified since there is no need to manually adjust positions of conventional probe needles. Further, semiconductor ICs having a lot of bump electrodes can be test without being damaged.
