Aligning tool set metrics for operation in a Multi Technology High Mix Low Volume manufacturing environment

Abstract

Ireland Fab Operations (IFO) is transitioning and leading the way within Intel to Multi- Technology High Mix Low Volume (MT-HMLV) manufacturing. To avoid errors in estimating metrics, specific capacity tool set metrics for this manufacturing environment now need to be considered. Approximations for high volume manufacturing may be far enough from MT-HMLV realities that company revenue is affected by making delivery commitments that can not be met. The Intel Model of Record (MOR) which is used to determine the number of each tool set needed to produce a given volume of product does not consider MT-HMLV realities. Things such as product change-overs, cross qualified tools, and smaller than 'normal' lot sizes can create chaos on the manufacturing floor that has not been traditionally accounted for.
