This thread is for discussing the lifecycle document "Business Case & Technology Choice: stage guide".
How a company decides whether a new fab, or a new phase of an existing one, is worth building, and on what technology, wafer size, capacity and phasing. It covers the demand outlook, the alternatives to building, the technology and capacity plan, the first tool list, the wafer cost model and the business case that funds site selection and design. It is written for strategy, finance, technology planning and process leaders and the executives who approve the investment.
