Latest Patents

Kaneko holds a patent for a GaP-base semiconductor light-emitting device. This invention involves a unique design where the main surface on the side of a p-type layer is defined as the first main surface, while the opposite side is the second main surface. The second main surface undergoes lapping and etching using aqua regia to create specular concave curved surfaces that enhance total light reflection. Conversely, the areas on the semiconductor substrate, excluding the first contact layer and the second main surface, are subjected to anisotropic etching to form outwardly-swelling convex curved surfaces, which help reduce total light reflection. The second contact layer is composed of an alloy of Au, Si, and Ni, while the first contact layer consists of an alloy of Au combined with either Be or Zn. This innovative design ensures a satisfactory level of luminance improvement, even with an emission mechanism that relies on indirect transition. Kaneko's patent is a testament to his expertise and creativity in semiconductor technology, with 1 patent to his name.
