These are separate issues. The transition to 300 mm wafers will allow more square chips to made from fewer round wafers by placing more on each wafer.

As you shrink the chips by using smaller lithography you can place more smaller chips on a single wafer. One problem is that as the chips shrink beyond .18 micron, it appears we leave the range of visible light; older mask generation equipment is not likely to be useful.
