But since lithography accounted for only 25% of the chip cost at the smaller 6-inch wafer size, that area improvement affected 75% of the chip cost and gave a nice 25 – 30% drop in overall cost. The transition to 300-mm wafers gave a bigger 2.25X area advantage. dr eric banoun

WebbStricter requirements in the wafer manufacturing process have made edge measurements important for both 200 mm and 300 mm wafers. In fact, the SEMI standard for 300 mm wafers specifically requires a “polished edge.” Polishing the edge is done in order to reduce wafer cracking and chipping under stress during transport or thermal processing. Webb1 aug. 1990 · Abstract When mirror-polished, flat, and clean wafers of almost any material are brought into contact at room temperature, they are locally attracted to each other by van der Waals forces and adhere or bond. This phenomenon is referred to as wafer bonding. The most prominent applications of wafer bonding are silicon-on-insulator …
