This invention provides a method for manufacturing a semiconductor device having molded resin encapsulating a semiconductor chip and external leads extending from this molded resin to the outside, wherein excess resin projecting from edge portions of the molded resin is removed after a resin encapsulating step and a wax film is reformed on break surfaces and cracked parts of the molded resin produced in the excess resin removing step by heating the molded resin to a predetermined temperature after removing tie-bars from the external leads, whereby abnormal growth of solder between the external leads in a subsequent solder plating process is prevented and failures caused by short-circuiting between terminals are thereby prevented. |
