having worked for a semiconductor company for 7 years, I know that wafer allocation and defect models are a huge area of concern. every wafer has defects and it behoves the manufacturer to figure out how to minimize the number of die that fall on obvious defect areas. not simple at all. more viable die per wafer, means a greater yield. since the wafer is a fixed cost, greater yield means lower cost per die. which means more profit (or greater market share due to lower price).
