Larger sizes ?
If a FAB is designed to make 28nm chips would it be capable of producing larger feature size chips (eg 40nm) or would the required processing conditions (eg temperature and chemicals) be too different ? If it is possible to produce the larger feature chips on a 28nm line then that could be a double win - use idle time on the 28nm line and produce some of the 40nm chips that are in short supply.
