Abstract
PURPOSE:To evacuate in vacuum a pot and a cavity before pressurizing resin and to form a package having no void by forming a discharging passage communicating with the cavity and the pot in a metal mold for forming a semiconductor resin sealing package, and connecting a suction unit thereto. CONSTITUTION:A space 23 is formed of communicating grooves 21, 22 communicating with both cavities 6, 7. A discharging hole 24 for forming a first discharging passage is opened out of a metal mold 1. A second discharging passage 27 opened with the inside and the outside of a pot 10 is formed due to the diameter difference from a sealing pin 28 in a plunger 11. The receiving face 11a of the plunger 11 is in contact with the receiving face 28a of the pin 29 to apply the injecting pressure of the plunger to synthetic resin 1. A suction unit is driven before pressurizing the resin to discharge air in the cavities 6, 7 from discharging passages 25, 27 to the exterior to eliminate the formation of surface and interior void of the package 5 due to the invasion of the air into synthetic resin 14 at the time of pressurizing the resin.
