a disaster with misalignment of the 200kW laser that damaged some other components

Sounds like the CO2 laser missed the tin plasma and struck the collector mirror on the other side. That's quite crippling. Wonder if they'll replace the source, even if the tool is running again.

Not sure EETimes attended the same papers I attended.  I heard both papers, and spoke with several colleaggue.  The consensus was universal: all believed in the Semiconductor Engineering version (link above).  The papers were anything but a revival.

Gridded arrays are being adopted by logic greatly simplifying the difficulty of printing patterns.

Yes indeed this would make things much simpler, we may not need more than two passes through 193i litho even for quadruple patterning at 7 nm.

Rick, that sounds good. I am probably a couple of months away from a full result set.

@ScottenJ: I'd love to do an interview on your assessment of the aternatives when you have the numbers together!

I haven't seen good cost estimates but that is actually my primary area of experitise these days.  I am currently working with several lithography and materials experts on detailed comparisons of all of the alternatives.

I can say that Intel has detailed plans through 10nm and they are forecasting that their cost per die is going to continue to go down ~30% for each of the 14nm and 10nm nodes. Intel is a little bit unique at the moment in that they are doing a full srink at 14nm where many foundries are maintaing the same BEOL for 14/16nm that they have at 20nm

@ScottenJ: Thankls for your take from the event, especially the other sessions you saw.

Have you heard any estimates of the kinds of cost adders people might see with quad and octal patterning?

@eejack: I suspect you are right. There are probably some pretty interesting shoes yet to fall.

LATEST ARCHIVED BROADCAST
As data rates begin to move beyond 25 Gbps channels, new problems arise. Getting to 50 Gbps channels might not be possible with the traditional NRZ (2-level) signaling. PAM4 lets data rates double with only a small increase in channel bandwidth by sending two bits per symbol. But, it brings new measurement and analysis problems. Signal integrity sage Ransom Stephens will explain how PAM4 differs from NRZ and what to expect in design, measurement, and signal analysis.
