It's all up in the air BUT what is different is that this is a game for far fewer players than it was at 300-mm and that concentrates the expense in relatively few pockets.
Could that make it a transition too far?
@Dylan: the "...the transition to 450-mm wafers is inevitable..." is only true to some, not all. I believe the number will be a small one. Given this, how are the 10 wafer fab equipment suppliers fund that 80 percent of the R&D required to support the transition?
Interesting forecast on the fab demography in 2017...
Thanks MP. I agree with you, and I suspect that Bob Johnson of Gartner would agree also. There will be only a few companies that move to 450. As far as how they will fund it, I suspect that we saw an example of that yesterday, when Intel announced it would take a stake in ASML and provide additional funding for 450-mm and EUV development. This is the way I think it has to be, because the tool vendors themselves are not going to be able to afford all of the R&D on their own.
Not sure that ASML should set the standard for all tool vendors, though I'm sure any vendor will now like to ask for upfront $$ to fund R+D. Regarding 450mm photo development, it seems we're really talking EUV. I believe there are some toolsets like implant that face significant challenges to upsize from 300mm to 450mm, but I would think that this asml example will be the exception, not the rule.
I am with you. I think every tool maker would like to get money up front for 450-mm development. But I am not sure that that many are negotiating from ASML's position of strength in lithography. Sadly, in more competitive equipment markets, bearing the cost of 450-mm development may be table stakes.
What is also interestng is what happens to 300-mm wafer fabs when the leading-edge digital logic and memory ICs are made in a very few 450-mm megafabs.
History teaches that the 300-mm fabs will become the domain of More-than-Moore, trailing-edge digital, 57 varieties of analog, mixed-signal, image sensors, MEMS and so on.
And most 200-mm wafer factories will probably become economically unviable if they are trying to compete with larger 300-mm wafer fabs.
The result will be a complete changing of the order.
And then, talking with the Cymer folks, their EUV teech will be rolling out before 450mm is ready, even on the most optimistic predictions, which could increase yields on 300mm enough to make 450mm unnecessary in the short term.
What are the engineering and design challenges in creating successful IoT devices? These devices are usually small, resource-constrained electronics designed to sense, collect, send, and/or interpret data. Some of the devices need to be smart enough to act upon data in real time, 24/7. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
