As semiconductor manufacturing technology advances, power dissipation and noise in scan testing has become a critical problem. In our studies on practical LSI manufacturing, we have found that power supply voltage drops cause testing problems during shift operations in scan testing and we have analyzed this phenomenon and its causes. In this paper, we present a new testing method named MD-SCAN (Multi Duty-Scan) which solves power supply voltage drop problems in scan testing, as well as offering… CONTINUE READING
