METHOD OF MANUFACTURING A SEMICONDUCTOR DEVICE |
摘要 |
A soldering method achieves little void and good joint condition in soldering an insulated circuit board and a semiconductor chip using a tin—high antimony solder material. A method of manufacturing a semiconductor device includes the steps of preparing a solder plate having a U-shape; mounting the solder plate on a substrate; mounting a semiconductor chip on the solder plate; fusing the solder plate in a reducing gas atmosphere; and reducing a pressure of the reducing gas atmosphere to a pressure lower than the atmospheric pressure when melting the solder plate. |
