Claim One:
1. An alarm apparatus for sensing occurrence of abnormality in a plant that manufactures products by processing substrates, the alarm apparatus comprising: means responsive to an inspection result of a surface of the substrates during manufacturing the products for aggregating degree of occurrence of defects for each monitoring unit region to produce an aggregation result, the monitoring unit region being configured by dividing a surface of the substrate and having a prescribed size configured for each type of the abnormality, the degree of occurrence of defects being aggregated by summing the inspection results of a plurality of the substrates; means for comparing the degree of occurrence of defects in each of the monitoring unit regions with a reference; means responsive to detection of the monitoring unit region with the degree of occurrence of defects being higher than the reference for transmitting an alarm and outputting the aggregation result; means for determining whether there is any manufacturing apparatus used in processing a prescribed proportion or more of the substrates on which the monitoring unit region with the degree of occurrence of defects being higher than the reference is detected; and means responsive to presence of the manufacturing apparatus used in processing the prescribed proportion or more of the substrates for outputting, along with the alarm and the aggregation result, information indicating the manufacturing apparatus used in processing the prescribed proportion or more of the substrates.
