  • Patent number: 5037780
    Abstract: A method for fabricating semiconductor devices comprising pressing first and second semiconductor devices against a transparent board at different times by means of first and second pressure tools that are separate from each other and move upward and downward independent of each other so that a difference in thickness between the devices and a deflection of the devices can be absorbed and a reliable electrical connection between the electrodes of the devices and the conductors of the board can be attained, which makes it possible to continuously achieve a highly dense assembly of semiconductor devices with a minute gap therebetween.
