Abstract
An apparatus for assembling semiconductor devices includes a transportation line for transporting partially fabricated articles such as lead frames with a semiconductor chip mounted thereon; a working unit disposed in the transportation line for processing the partially fabricated articles by wire bonding or die bonding; an inspection unit disposed separately from the transportation line; a delivery unit for extracting a processed article from the transportation line, moving the extracted worked article to an inspection section and returning the processed article to the transportation line after checking; and a stock unit for stocking the processed articles. In the inspection section, one of the processed articles selected for sampling inspection is placed on a support and is checked with a microscope. During checking, the support and the microscope can be moved relative to each other to enable observation of the whole of the selected article.
