Abstract
A plurality of semiconductor chips are mounted on an insulating substrate with bumps and through use of dielectric resin for mounting purposes. The semiconductor chips are sealed with transfer mold resin through a single operation while remaining on the insulating substrate. Then, the plurality of semiconductor chips are separated together with the insulating substrate and the mounting resin into individual semiconductor devices. The productivity and reliability of packaged semiconductor devices is improved.
