摘要: A method for manufacturing an intermediate to a vertical III-nitride semiconductor device comprising a shielding structure (5), the method comprising:
a. obtaining a stack of layers (3) in a reaction chamber of a vapor-phase epitaxy reactor, the stack of layers (3) comprising:
a III-nitride semiconductor stack (1), and
a patterned mask layer (2), the pattern comprising a first region (21) comprising mask material and a second region (22) not comprising mask material and exposing a region (10) of the III-nitride semiconductor stack (1), and
b. controlling the reactor so as to:
b1. selectively desorb material from the region (10) of the III-nitride semiconductor stack (1) exposed by the second region (22) of the patterned mask layer (2) so as to form a trench (4), then
b2. form the shielding structure (5) by epitaxially growing, in the trench, the III-nitride material doped with the p-type dopant.-

摘要: A step-flow growth of a group-III nitride single crystal on a silicon single crystal substrate is promoted. A layer of oxide oriented to a axis of silicon single crystal is formed on a surface of a silicon single crystal substrate, and group-III nitride single crystal is crystallized on a surface of the layer of oxide. Thereupon, a axis of the group-III nitride single crystal undergoing crystal growth is oriented to a c-axis of the oxide. When the silicon single crystal substrate is provided with a miscut angle, step-flow growth of the group-III nitride single crystal occurs. By deoxidizing a silicon oxide layer formed at an interface of the silicon single crystal and the oxide, orientation of the oxide is improved.
