re: Panel reveals concerns over 450-mm wafer work

I agree with your sentiment Kris. Europe has worried for over a decade than semiconductor manufacturing will leave and only be done in the U.S. and in Asia. Crolles was largely paid for by the French government to keep high tech industry in France. The odds are becoming higher that it will leave Europe if European governments do not provide funding. Intel has been seeking 450mm wafers for about a decade since its manufacturing is restricted by 300mm wafers. TSMC is also starting to come to the same conclusion as Intel. My own guess is we will see 450mm wafers in the next 5 to 8 years. 300mm wafers frankly would not be competitive compared to 450mm wafers at 40nm technology. The fabs can take a break from Moores Law somewhere below 20nm and gain efficiency and yield advantages with 450mm wafers. This will give lithography development some breathing room. Intel, TSMC, and Samsung will lead the way. It is in their interest to force this shift. Some additional fabs may eventually make the transition as well depending on funding sources.

The move to 450mm wafers is very expensive. For the captial cost to pay off, you have to run a lot of wafers. Only very large companies with deep pockets can do this. That is why the article states that this might cause the industry to collapse to only a few companies. As long as the smaller (12 inch is small?) wafer sizes can still compete on price, there is no worry of a collapse.

Interesting debate...I agree that if there are 3-4 players left after transition to 450-mm wavers Europe is in trouble...Intel will fab processors, Samsung memories, and TSMC/GlobalF the rest...Europe's fabs will all become boutique foundries unless they all pitch-in together and extra billions from European taxpayers somehow...Kris

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.
