A large number of leads including an inner lead 7 connected to the semiconductor element 4 by a wire 6 and an outer lead 8 connected to the inner lead 7, and 9 is a connecting piece for preventing resin flow interposed between the inner leads 7 of these leads 5. It is. 10 is the semiconductor element 4. This is a sealing resin that seals the wire 6 and the inner lead 7.

形品を取り出す。First, the lead frame before resin sealing is positioned on the lower template of the two upper and lower templates using positioning pins. Next, after the mold is clamped by both upper and lower mold plates, a resin tablet is inserted into the pot of the mold plate and pressurized with a plunger. At this time, the resin tablet is heated and melted to become a molten resin, which is filled into the cavity via the runner and the gate. After that, the mold is opened and the molded product is taken out.
このようにして、半導体装置の成形品を製造することが

A large number of leads each having an inner lead connected to the semiconductor element on the die pad by a wire and an outer lead connected to the inner lead, and a connecting piece for preventing the flow of sealing resin interposed between the inner leads among these leads. This connecting piece is made of an insulating material.

ャーによって加圧してから型開きをするのである。A molded product of a semiconductor device can be manufactured using the lead frame configured in this manner in the same manner as in the conventional method. That is, the lead frame before resin sealing is positioned on the lower template of the two upper and lower templates using positioning pins, and then the mold is clamped by both the upper and lower templates, and then a resin tablet is placed in the bottom of the template.
