@Rick :

I wonder if TSMC is now doing REAL 3-d stack ( i,e. TSVs in active dice and stacking them ) or still just 2.5-d ( NO TSVs in the active dice, no active die on top of another ) like their earlier Vertex modules for Xilinx.

Your point about difficulty is however well taken. It took Micron at least 2 years to start sampling their HMC, a true 3-d stack.

But many technical questions ( ideal materials set & process flow, yield, device perf., reliability ) that still need to be settled re: 3-d w/ TSVs.

TSV is a very promising technology for 3D

If it clicks for SMIC then success in developing and implementing TSV technology will be game changing success for them, as further acceptance of 3D manufacturing of silicon is totally dependent of the success of TSV.

Rick, that's definitely a good data point.

Interesting the SMIC news comes the same day TSMC announced it was finally in volume production of Xilinx 2.5-D FPGAs. TSMC was early here and it seems the tech is harder than anyone thought.

Battle of 3D ICs

What's clear from SMIC's announcement today is the emerging battle -- over who gets more market share -- in the 3D IC foundry business.

Do you see any foundries doing better than others when it comes to producing TSV technology-based stacked devices?
