Patent ID: 7640126

Claim:
A combine-information processing apparatus comprising: an inspectional equation storage unit in which an inspectional equation for calculating one or more principal component scores can be stored, said inspectional equation being obtained by performing a principal component analysis on normal measured data that is measured data regarding a plurality of measuring objects in terms of two or more correlated measurement items, and said plurality of measuring objects being processed by a manufacturing apparatus whose adjustable conditions are changed while said manufacturing apparatus is in a normal state; an inspected measured-data acceptance unit for accepting inspected measured data that is measured data regarding the measuring objects processed by said manufacturing apparatus in terms of the measurement items corresponding to each term contained in said inspectional equation; a principal-component-score calculation unit for calculating the principal component scores using the inspected measured data, accepted by said inspected measured-data acceptance unit, with said inspectional equation; an inspecting unit for inspecting the state of said manufacturing apparatus using the principal component scores calculated by said principal-component-score calculation unit; and an output unit for outputting inspecting results obtained by said inspecting unit.
