Configuration of a Manufacturing Line for Mixed Production of Ultra-Short TAT LSIs and Low-Cost LSIs

摘要

We propose a method for configuring LSI manufacturing lines so that they can not only be used to manufacture low-cost LSIs in bulk quantities but also can be used to manufacture small lots with ultra-short TAT. This is achieved by adding a relatively small amount of single-wafer processing equipment to a existing conventional processing line, and therefore involves minimum investment.
