Abstract
The present disclosure discloses a trench Insulated Gate Bipolar Transistor (IGBT) packaging structure and a method for manufacturing the trench Insulated Gate Bipolar Transistor packaging structure. The trench IGBT packaging structure includes: a trench IGBT, which includes an emitting electrode metal layer, and a trench gate electrode; a lead frame, which includes a chip placement area and an emitting electrode lead-out end; a first bonding wire connecting the emitting electrode metal layer and an emitting electrode pin. One end of the first bonding wire is connected to a surface, away from the trench gate electrode, of the emitting electrode metal layer to form a strip-shaped first solder joint, the other end is connected to the emitting electrode lead-out end to form a second solder joint, and an extension direction of the first solder joint is perpendicular to an extension direction of the trench of the trench gate electrode.
