Abstract
A method is provided to suppress detachment between semiconductor packages while preventing dislocation at the time of mounting a stacked semiconductor package on a motherboard. Semiconductor packages PK1 and PK2 are bonded to each other through protruding electrodes and resin is provided between the semiconductor packages PK1 and PK2. The resin is provided in the peripheries of the protruding electrodes so as to contact each of the protruding electrodes while not contacting a semiconductor chip.
Claims2
A method of manufacturing a semiconductor device, comprising:
- providing flux, which contains resin, on lands formed on a first semiconductor package;
- arranging solder balls, provided on a second semiconductor package, on lands provided with the flux;
- and
- melting the solder balls to bond the solder balls to the lands by executing a reflow process while making the resin contained in the flux crawl up along surfaces of the solder balls during the reflow process.
A method of manufacturing a semiconductor device, comprising:
- providing flux, which contains resin, on lands formed on a first semiconductor package;
- arranging solder balls, provided on a second semiconductor package, on lands provided with the flux;
- and
- melting the solder balls to bond the solder balls to the lands by executing a reflow process while simultaneously making the resin contained in the flux crawl up along surfaces of the solder balls during the reflow process.
