摘要: A tunneling-open failure mode is proposed and carefully studied. circuit with a tunneling open could pass at-speed Boolean tests but fail VLV testing or I/sub DDQ/ testing. Theoretical calculations as well experiments confirm the existence of opens. The Murphy experimental data show that seven out nine VLV-only circuits can be explained by this mode. All these survived 366 hours temperature burn-in. Finally, cost effective screening strategy proposed.
