Abstract:
A method of manufacturing a known good die comprising the steps of:providing a substrate having a plurality of metal lines formed on one surface thereof and having a plurality of conductive pins which are projected from an opposite surface of the substrate and which are electrically connected to the metal lines;forming an adhesive film, having a melting point of about 150.degree. C., on the surface on which the metal lines are formed;adhering an integrated circuit chip having a plurality of bonding pads and a plurality of bumps each formed on the respective corresponding bonding pads, on the substrate through the adhesive film such that the bumps each are aligned to the respective corresponding metal lines;carrying out a burn-in test of the integrated circuit chip;separating the integrated circuit chip from the substrate by vaporizing the adhesive filmpositioning the integrated circuit chip on the adhesive film in a state that the bumps of the integrated circuit chip face the metal lines of the substrate and are aligned with the metal lines of the substrate; andpressurizing the integrated circuit chip downward at a glass transition temperature of the adhesive film or less.
