Abstract:
1. A method for manufacturing a vertical nitride semiconductor device, the method comprising: preparing a conductive substrate and a semiconductor layer and forming a bonding layer on at least one of the conductive substrate and a second electrode, the semiconductor layer being formed on a front surface of an insulating substrate, having the second electrode bonded thereto, and being made of nitride; bonding the semiconductor layer prepared in the preparing step to one front surface of the conductive substrate via the bonding layer; removing the insulating substrate from the semiconductor layer; forming a first electrode on the semiconductor layer and forming a metal layer on the conductive substrate; cutting off the semiconductor layer and part of the conductive substrate in a thickness direction so as to expose a side surface of the semiconductor layer and a side surface of the conductive substrate, thereby forming a plurality of remaining parts of the conductive substrate to manufacture a plurality of laminating devices connected to each other by the remaining parts of the conductive substrate; and dividing the remaining parts of the conductive substrate to manufacture the plurality of vertical nitride semiconductor devices each having a flange part.
