Hi there, I was wondering if wafer costs vary significantly based on the type of product being produced. For example, if we're building a 28nm product for Logic vs. a 28nm product for power semiconductors (IGBT), will the wafer price/ASP (average selling price) significantly differ between the two?
I'm basically wondering if this chart is a good gauge for all types of products produced on a certain node type (within a range of course, I don't expect it to be exact). In fact, I read that this chart wasn't too accurate at the advanced nodes, but I'm more interested in the price of wafers in mature technology. Thanks!
I have seen several articles recently discussing foundry wafer selling prices for leading edge wafers, these articles all quote estimates from a paper by the Center for Security and Emerging Technology (CSET). The paper is available here. My company IC Knowledge LLC is the world leader in cost...

I'm not familiar with IGBT wafer pricing, can't you just call TSMC or GF?
They are dramatically different. IGBT processes are much simpler and there is no such thing as a 28nm IGBT any way. IGBTs are typically 600 volts plus and there is no reason to use such small line widths. If you really want to know what IGBTs cost you can buy our Discrete and Power Products Cost and Price model available here: https://www.icknowledge.com/products/powermodel.html
