fatslob-:O said: The reason why Intel was slow to move Atom for cutting edge lithography is cause they didn't want to compromise on higher margin parts but if they had some extra fab capacity then they would've without doubt moved Atom on to more cutting edge lithography instantly ... The older technology, the cheaper it is mentality doesn't apply to chip manufacturing since newer process nodes have ALWAYS provided cost reduction aside from 28/22nm and below ... |
It provide reduction in costs after the mature of the new tech... at start a 28nm process will cost more than a mature 40nm for a series of reasons: production line not optimized to the new process, issues with the process (here you can be a lot of things that make the % of good yelds be really low) and low utilizations of the process.
Most companies start making only a chip in the new process until it gets mature enough to move all chips.
But yes... a solid and matured 28nm process will be always cheaper than a solid and matured 40nm process.
