Fab 36 will be a full-capacity 300-mm fab. Fab 38 will likely be a
small-capacity 300-mm fab, producing maybe only half as much as Fab 36
can. Then Fab 40 would be another full-capacity fab. Part of the reason
that Fab 38 will be smaller capacity than the other two is because a
bump-and-test building will be built right into it which will serve the
other fabs too; this will reduce the amount of space available in Fab
38.
