The cooperation between the four companies is yet another sign of quickly rising cost for semiconductor research and development, which forces most chip manufacturers into collaboration efforts to make the economics work. According to a press release distributed by IBM, Chartered, Infineon and Samsung, the joint-development of 45 nm technology may "facilitate [an] earlier transition to the new process" and enable "multi-fab manufacturing capability for maximum design leverage" by using a single design approach. The companies expect their 45 nm process to be installed and fully qualified at Chartered, IBM and Samsung 300 mm fabs by the end of 2007. Mass production is scheduled to begin sometime in 2008.
Well, IBM and AMD are partners on this one. I wouldn't be surprised if AMD offers 45nm chips a few months after intel's since that's what they were saying a while ago.
