Latest Patents

One of his latest patents is a light emitting device that features a structure where a p-type InGaAs layer serves as an electrode contact layer, and an ITO electrode layer functions as an oxide transparent electrode layer. This configuration is formed on the first major surface of a light emitting layer section. On the second major surface, an n-type InGaAs layer is also used as an electrode contact layer, along with another ITO electrode layer. The ITO electrode layers, together with the p-type and n-type InGaAs layers, cover both major surfaces of the light emitting layer section entirely. Another notable patent is for a GaAsP-based light emitting element that maintains excellent light emission properties over time. This element features a p-n junction interface formed between a p-type GaAsP layer and an n-type GaAsP layer, with a nitrogen-doped zone included at the p-n junction interface. The manufacturing method involves varying the nitrogen concentration while keeping the mixed crystal ratio constant, allowing for optimization of emission luminance.
