Answer 1

bigger chips is not cost effective for manufacturers, as these thnigs are produced in Silicon wafers which are individually expensive. so there is a economical interest in fitting as many chips as possible per Unit.

this also falls into the 2nd part: Yield, some chips will be faulty at production, a smaller chip means a faulty unit wont be as much of a loss.
