Abstract :
Assuring full electrical performance of known good die is a continuous issue for semiconductor manufacturers. On the other hand, reducing test costs is also a constant issue for semiconductor manufacturers. This paper describes a method to satisfy both needs on a mixed-signal device by multi-die probing. 4-die probing for 16 bit Δ Σ DAC was attempted using the HP9490 mixed-signal LSI test system and a vertical contact probe card. A comparison of analog characteristics between wafer probing and final test, yield, and test throughput is discussed
