Apparently this is a stacked device, and a technology node of 22 nm is claimed. Is the 22 nm the technology node for the top layer (= light sensitive part), for the bottom layer (= processing part) or for both ? This is not really clear from the press release.
ReplyDeleteDon't know for sure, but similarly to Sony/Samsung/OmniVision I would think they are using the 22nm technology node for the bottom layer.
ReplyDeleteIt would be more helpful if they show number, rather than saying 20% increase, 20% reduction.
ReplyDeleteI already complained a hundred times about this, but it does not help ....
