2. Doubled size of IC

Try doubling the size of the IC to make a more powerful CPU...
    40 ICs attempted
   - 4 defective ICS
    -- -------------
    36 good ICs -- a 90% yield

x $240 per IC (Twice previous cost
 -----            PLUS 20% premium)
 $8640
-  360 (same labor/packaging costs
 -----                   at $10/IC)
 $8280 "profit"

 -- a $1440 increase
     over Standard Process!!
