Title: The Innovations of Takeshi Kamikawa
Introduction
Takeshi Kamikawa is a prominent inventor based in Santa Barbara, California. He has made significant contributions to the field of semiconductor technology, holding a total of 7 patents. His work focuses on methods that enhance the fabrication and performance of III-nitride semiconductor layers.
Latest Patents
One of Kamikawa's latest patents is a method for flattening a surface on an epitaxial lateral overgrowth (ELO) layer. This innovative approach results in a smooth surface with island-like III-nitride semiconductor layers. The method involves stopping the growth of the ELO layers before they coalesce, followed by the removal of a growth restrict mask. This process decreases the supply of excess gases to the side facets of the island-like layers, ultimately leading to a smoother surface. Additionally, this method prevents the compensation of a p-type layer by decomposed n-type dopants from the mask, such as Silicon and Oxygen atoms.
Another notable patent by Kamikawa is a method of fabricating non-polar and semi-polar devices using epitaxial lateral overgrowth. This method includes forming a growth restrict mask on a III-nitride substrate and growing island-like III-nitride semiconductor layers. The substrate features an in-plane distribution of off-angle orientations, which range from about +28 degrees to about −47 degrees towards a c-plane. The island-like layers are designed to have distinct long and short sides, with the long side being perpendicular to the a-axis. Importantly, these layers do not coalesce with neighboring layers, allowing for enhanced device performance.
