Latest Patents
Izumi's latest patents showcase his expertise in creating innovative manufacturing processes for LEDs. His patents include:
1. **Method of manufacturing a light emitting diode** - This patent outlines a method that involves bringing a semiconductor substrate of p-type or n-type into contact with a growth solution at a high temperature. Subsequently, the temperature is lowered to form a monocrystalline epitaxial layer of the same type as the semiconductor substrate. Following this step, additional lowering of the temperature allows for the formation of a first monocrystalline epitaxial layer of a reverse type to the initial epitaxial layer. The process concludes with an epitaxial wafer being created after cutting off the growth solution, resulting in a second monocrystalline epitaxial layer of the same kind as the first on top of it.
2. **Method of manufacturing a light emitting diode using LPE at different temperatures** - Similar to his first invention, this method details the process of using a growth solution at high temperature before lowering the temperature to create monocrystalline epitaxial layers. This technique enhances the efficiency and performance of LEDs, making them more reliable for various applications.
