Let us consider the following data for a semiconductor design company “X”:
• Actual yield, Y = 0.9
• Die area A = 1.5 cm × 1.5 cm
• Dies are processed on an R = 200 mm diameter wafer at $1500/wafer
• Each mask cost $100,000 (Total 10 masks)
• 5-man development team at $200,000 per designer
• CAD tool costs are $1,000,000
• Market for this part is 2,000,000 units
1. If the company wants to make 10% profit on each chip, what would be the cost of the chip in the market, calculate the cost of each chip for the semiconductor design company X?
2. Calculate the number of out-of-spec (due to yield) chips per wafer. Assume that a rogue Assembly want to sell these out-of-spec chips in the marker. How much profit will he/she make per each wafer?
