So is the innovation using Ti as a barrier in sputtering Cu? Or is that just incidental information?

Cu as filling of TSV has already been used since long time ago.

Using Ti instead of tantalum as barrier cuts cost according to AM. Cu goes inside the barrier--as usual.

Misleading Headline?

While I agree that AMAT's HVM tool for PVD of barrier and seed layers is exciting news, lets not get ahead of ourselves by making false claims in the title just to get the click-throughs. TSVs will go into HVM when the volume orders start rolling in from customers. A more accurate title would be "HVM PVD Tool Enables Industry to Manufacture 3D IC Stacks in High Volume."

You are right; this is actually a incremental development or stepping stone for the high volume production of 3D Chips. This kind of incremental developments are really required in increasing manufacturability of 3D Chips.

I also think that these are incremental improvements but whether there are enough for companies to switch to 3D stack for cost is not yet clear.

I don't write the final headline, my suggested headline read:

World's First 3-D TSV Volume Manufacturing Tool

But in defense of our headline writers, AM does already have 30 customers, some working with the tool for as long as 18 months, which "sends" could resonably be argued to accurately describe :)

and how many of those 30 customers for this AMAT tool are using it for TSVs ??

I assumed that all 30 are using Ventura for TSVs, but I just checked with Applied Materials to make sure my memory served me well, and they confirmed that Applied Materials has "sent 30 chambers to multiple customers.  And yes, Ventura was developed specifically for fabricating TSVs."

Thank you very much for your query. Its good to make sure that all our published facts are checked and verified. Thanks again.

That will require another incremental development to correctly mould this idea in actual practice including cost concerns.

David Patterson, known for his pioneering research that led to RAID, clusters and more, is part of a team at UC Berkeley that recently made its RISC-V processor architecture an open source hardware offering. We talk with Patterson and one of his colleagues behind the effort about the opportunities they see, what new kinds of designs they hope to enable and what it means for today’s commercial processor giants such as Intel, ARM and Imagination Technologies.
