What factors will affect the cost of a wafer?

[littleming]

Dear all,

When I get my chip fabricated by some foundry(e.g. tsmc), what factors will affect the cost of a wafer (how much money I have to pay)?
Wafer Size(300mm/450mm)? Number of metal layers? Technology node(.18/.13)? and what else?
Is there any method to estimate this thing?

Thanks a lot!

Added after 1 hours 52 minutes:

and what's the rough value for different size wafer?

I found some data, but I'm not sure whether it's correct.
8-inch : $1000 per wafer
12-inch: $4000 per wafer

how much does a wafer cost

Costs vary from fab to fab and they depends mainly on the technology node.
The more aggressive the technology, the more expensive the wafer.
In reality, the big cost is related to mask building. So, the $/wafer is depending on the total number of wafer you need.
