Title: Method and device for testing integrated circuits on wafers
Inventor: BRAU LUCIEN
IPC: H01L21/66
Filed: 1984-05-30
Abstract: In order to increase the speed of an individual test on a wafer carrying integrated logic circuits, two chips A and B joined by one of their corners are tested simultaneously by applying the same logic test signals AX0 to AX6; AY0 to AY3 to both chips after having previously made a similar (leakage current) test separately on each of them. The test plugboard therefore carries twice as many contacts as are required for a single chip. It also carries a switching circuit RL1 to RL7 to enable the test signals to be applied separately or simultaneously to both chips. Application to testing non-volatile integrated memories.
