Abstract

A process for producing a semiconductor wafer having an adhesive film, by adhering an adhesive film onto a bump-formed surface of a semiconductor wafer having formed thereon bumps with a predetermined arrangement, which comprises: determining a particular arrangement axis direction in which intervals between adjacent linear arrangement axes connecting the bumps becomes the shortest; and adhering the adhesive film in the direction substantially at a right angle with the determined arrangement axis direction, so as to markedly reduce voids included in the adhesion surface upon adhering an adhesive film such as underfill onto a semiconductor wafer.
