1. Standard Production Yield

Let's consider a process where the resulting integrated circuit is shown as a square on the wafer at left.
    80 ICs attempted
   - 4 defective ICS
    -- -------------
    76 good ICs -- a 95% yield

x $100 per IC
 -----
 $7600
-  760 (labor/packaging costs
 -----              at $10/IC)
 $6840 "profit"
