Textbook Question
Chapter 28, Problem 22QLP
The table that follows describes three wafer-manufacturing changes: increasing the wafer diameter, reducing the chip size, and increasing process complexity. Complete the table by filling in “increase,” “decrease,” or “no change,” and indicate the effect that each change would have on the wafer yield and on the overall number of functional chips.
| Change | Wafer yield | Number of functional chips |
| Increase wafer diameter Reduce chip size Increase process complexity |

Q1 – Area vs Die/wafer – a) What is the area ratio between a 300mm and 200mm diameter wafer? (The 300mm diameter waferhas x.xx times the area of a 200mm).b) How many 15x15mm die can be completely printed on a 100mm, 200mm, and 300mm wafer? Showyour work. Do not include partial fields; you may assume no scribe lines or edge exclusion zone. Thereis no flat, only a notch for the 200mm and 300mm wafers. How many times more die can you getwhen going from 200 to 300mm wafers? How does this number compare to the area increasebetween 200 and 300mm? c) Now assume a 100um scribe line and a 3mm edge exclusion zone. How may die per wafer for 200mmand 300mm wafers? How did you calculate this – show your work. How does this compare to the arearatio? Is it the same? If not, why not?
Calculate the number of finished goods (output) or N for the manufacturing process illustrated in the next page.
