摘要
A novel method for the inspection of the stacking misalignment in three-dimensional integration circuit (3DIC) by using electrical measurement is proposed. The metal line pattern designed in this paper combined with bump-less TSV fabrication process can successfully detect the direction and quantity of stacking fault. In addition, circuit combined with testing structure can be developed and simulated by using the current mirror concept and offered measurements with better efficiency.
