Latest Patents

One of his latest patents is for a semiconductor light emitting device. This device includes a substrate, a common conductive portion formed on the substrate, a semiconductor light emitting element mounted on the common conductive portion, and an electronic component mounted on the common conductive portion. This structure shortens the conductive path between the semiconductor light emitting element and the electronic component, thereby reducing capacitance caused by the conductive path. As a result, while reducing parasitic capacitance, the semiconductor light emitting element and the electronic component are electrically connected. Another notable patent is for a surface-emitting semiconductor laser. This laser includes a first-conductivity-type layer, an active layer, and a second-conductivity-type layer. The active layer and the second-conductivity-type layer are electrically connected in a current constriction layer through an opening. The surface-emitting semiconductor laser also features an insulating layer that has translucency with respect to the emission wavelength of the active layer, along with first and second electrodes connected to the respective layers. The design of the insulating layer is such that it enhances the efficiency of light emission.
