Latest Patents
Yokota's latest patents include a method for making a compound semiconductor single-crystalline substrate for liquid phase epitaxial growth. This innovative method is designed to be cost-effective while maintaining excellent practicality. The substrate is prepared to have a surface roughness of at least 1 µm and not more than 10 µm, measured over a line of 1 mm length. This substrate is particularly useful for epitaxial wafers used in infrared or visible light-emitting diodes. The specific roughness of the substrate prevents slipping or falling during transportation in processing. Additionally, the manufacturing process eliminates the need for lapping and polishing, further reducing costs.
