Latest Patents

One of his latest patents is a semiconductor substrate manufacturing method. This method involves epitaxially growing a columnar III nitride semiconductor single crystal on a principal place of a circular substrate. It includes the removal of a hollow cylindrical region at the outer peripheral edge of the III nitride semiconductor single crystal, leaving a solid columnar region inside. The process ensures that the shape of the III nitride semiconductor single crystal maintains axial symmetry, with the center axis defined as the symmetric axis.

Another significant patent is a nitride semiconductor single crystal substrate manufacturing method. This method entails providing a template where a first nitride semiconductor single crystal layer is hetero-epitaxially grown on a heterogeneous substrate. It involves forming a plurality of linear grooves on the template's surface, which reach the inside of the heterogeneous substrate. The pattern of these grooves exhibits three-fold or six-fold rotational symmetry concerning the central axis of the template. Subsequently, a second nitride semiconductor single crystal layer is epitaxially grown on the template, and a nitride semiconductor single crystal substrate is cut from this layer.
