有點忘了，怎麼算這個東西..
Assume you are in a company that will market a certain IC chip.
The fixed costs, including R&D , fabrication and equipments, and so on , add
up to $500,000. The cost per wafer is $6000, and each wafer can be diced into
1500 dies. The die yield is 50%. Finally, the dies are packaged and tested,
with a cost of $10 per chip.The test yield is 90%; only those that pass the
test will be sold to customers. If the retail price is 40% more than the cost,
at least how many chips have to be sold to break even?
Cost Per Die = Cost per wafer/(Dies per wafer x Yield)
麻煩各位幫忙了
謝謝
