Vince says we switched from Nextreme to Easicopy, Puppet says we should do Nextreme with Easicopy happening in parallel for later.
I would like to draw everyone's attention to the following diagram (pay close attention to the first step in purple, as it's a requirement for both approaches):
[...]
As such, the wisest move would probably be to do both, in parallel, but only after checking some samples work (Nextreme).
Nice digging, lucky I caught it in this maelstrom of trolling. Pretty much confirmed what I thought, however, it also strongly suggests my earlier hypothesis is correct: nextreme 3 is not ready. Your links refer to nextreme 2. No reason to assume the flow is any different, even the timing will be pretty much identical, but try to find any information or PR or whatever on Nextreme 3 on easic's site and you will draw a blank. ebeam might only take hours, but if you dont have prefabricated nextreme 3 wafers to apply the ebeam process to, that doesnt help you.
