Latest Patents

Yuanyuan Yu holds a patent for a superjunction device. This device features a unique design where the corner portions of each annular-shaped second trench are composed of a plurality of alternately arranged first sides and second sides. The first sides are parallel to a series of first trenches in a current-flowing area, while the second sides are perpendicular to the first sides and the first trenches. This design ensures that the Miller indices of the sidewalls and bottom face of any portion of each second trench belong to the same family of crystal planes. Additionally, the corner portions of the second trenches can be filled with silicon epitaxial material at the same rate as the rest of the portions, ensuring uniform and defect-free filling, which ultimately improves the performance of the superjunction device.
