Latest Patents

One of Takano's latest patents involves an epitaxial substrate that features a single crystal substrate with projections arranged in an array on a plane. Each projection is designed with a conical or pyramidal shape that tapers in a normal direction to the plane. The AlN layer in this patent includes a first AlN crystal that covers both the plane and the projections, with the tips of the projections being exposed. Additionally, second AlN crystals protrude from the tips of the projections, taking the shape of columns whose cross-sectional area increases as the distance from the tip increases. A third AlN crystal serves as a layer that interconnects the ends of the second AlN crystals, opposite the single crystal substrate.

Another notable patent by Takano is for an organic electroluminescence element and lighting device. This element comprises a moisture-proof substrate, a light-emitting stack that includes a first electrode, a light-emitting layer, and a second electrode, along with an enclosing member that bonds to the substrate to enclose the stack. The design also features a light-outcoupling structure on the side of the substrate facing the first electrode, which has an uneven structure made of material with a refractive index almost equal to or lower than that of the substrate. The uneven structure is divided into a matrix of sections, with multiple protruded parts having nearly the same heights allocated to specific sections of the matrix.
