Ideal 3D Stacked Die Test - Ira Feldman - IEEE SWTW2013

I had the pleasure of presenting “Ideal 3D Stacked Die Test” in Session Two “Industry Trends and Advanced Packaging Challenges” of the 23rd annual IEEE 
Semiconductor Wafer Test Workshop (SWTW) on Monday June 10, 2013.

Integrated circuits using 2.5D advanced packaging are shipping. 3D packaging with thru-silicon vias (TSV) has been demonstrated. “5.5D” packages may not be far behind. Probe card suppliers have made progress building interconnect technology for the micro-bump arrays. Standards committees have started defining IC interface standards and test access protocols.

But what does the Test Engineer and Management really want? What can they afford? What are the most likely scenarios? Factors that determine which test technology can support the desired test flow are examined. In particular, probe card technology for probing TSV bumps and potential usage models are reviewed.
