Semiconductor device

The utility model relates to a semiconductor device. The utility model discloses an aim at of an aspect provides the semiconductor device that a not controlled reducible or that the elimination tube core attaches to connect the material removed. The utility model relates to a semiconductor device, include: the lead frame, the setting is in the electrically conductive barrier material of non - on the first side of lead frame partly, the setting is in the lead frame tube core on first side partly attaches the material of connecing, and the electrically conductive barrier material in its central africa does not have on setting up and have the first side that the tube core attaches the first region partly at least that connects the material and substrate in the first side of lead frame the tube core attaches between the second district that connects the material, and attaches the semiconductor tube core that connects to the at least first region of the first side of lead frame. The utility model discloses a techn
