Abstract
A burn-in test process is omitted for some or all lots. In burn-in necessity determination processing, whether each semiconductor chip requires a burn-in test to be performed is determined based on measurement data obtained in a probe test process. In an assembly process, based on the results of determination made in the burn-in necessity determination processing, the assembled packages are sorted into a first lot which includes packages each including a semiconductor chip determined to require a burn-in test to be performed and a second lot which includes packages each including a semiconductor chip determined to require no burn-in test to be performed. In a burn-in test process, only the packages of the first lot are subjected to a burn-in test.
