Patent ID: 6905913

Claim:
A method of manufacturing a semiconductor device wherein first and second semiconductor elements different in performance are sealed with a resin, comprising the following steps: a step for determining the second semiconductor element, wherein one capable of implementing a desired function in cooperation with the first semiconductor element, of a plurality of semiconductor elements respectively having different performance, is selected as the second semiconductor element; a step for electrically connecting the first and second semiconductor elements to each other, wherein said first semiconductor element has a plurality of first pad electrodes and a plurality of second pad electrodes placed over a main surface of said first semiconductor element, said first pad electrodes are used for electrically connecting to their corresponding ones of a plurality of terminals for connection to the outside, and electrical connections of said first semiconductor element to said second semiconductor element are carried out by using the plurality of second pad electrodes; and a step for sealing the first and second semiconductor elements electrically connected to each other with a resin.
