Abstract:
1. A method of controlling a semiconductor processing apparatus, the semiconductor processing apparatus storing a recipe group and the method comprising: setting processing conditions, wherein the processing conditions comprise a set recipe; loading a lot into the semiconductor processing apparatus; performing a validation process to determine whether the set recipe is within the recipe group; performing an identification process, wherein the identification process comprises determining whether the quantity of wafers indicated by the basic process information is correlated to the quantity of wafers read by the semiconductor processing apparatus through lot mapping; starting the semiconductor fabrication process according to the set recipe, if the quantity of wafers indicated by the basic process information is correlated through lot mapping to the quantity of wafers read by the semiconductor processing apparatus and if the set recipe is within the recipe group, or determining that there is a process failure in the semiconductor fabrication process and unloading the lot from the semiconductor processing apparatus, if the quantity of wafers indicated by the basic process information is not correlated through lot mapping to the quantity of wafers read by the semiconductor processing apparatus; and, performing an invariability check process during the semiconductor fabrication process, wherein the invariability check process determines whether a current recipe of the semiconductor processing apparatus is correlated to the set recipe, wherein setting processing conditions comprises:
