The semiconductor industry’s introduction of 300 mm wafers required addressing some significant manufacturing challenges. The industry is now contemplating 450 mm wafers. Respondents to a survey conducted by Wright Williams & Kelly, Inc. (WWK) in April of 2007 suggested that the challenges to 450 mm wafer introduction may be economically insurmountable. WWK followed up on the survey results by using economic models to compare profitability of 300 mm and 450 mm wafer fabs based on current manufacturing and economic trends. This article will look at some of the challenges that 300 mm manufacturing overcame and some of the anticipated challenges that 450 mm manufacturing must address.
