Abstract :
TAT cost standard is defined and proposed by a relation between lot size, TAT and wafer cost in this paper. How to treat large variations of waiting time in a site data is excogitated. Proposed TAT costs equations and corrections can be used in a short TAT rate charge, TAT management etc. of many lines and products.
