Latest Patents
Ota's latest patents include the development of an indium phosphide wafer and a method for producing a monocrystalline indium phosphide. This innovative photoelectric conversion element utilizes group III-IV compound semiconductor single crystals containing zinc as an impurity as a substrate. The method allows for the substrate to be increased in size without compromising conversion efficiency. A heat-resistant crucible is employed, filled with raw materials and a sealant, which are heated to create a melt. The encapsulant is softened and covers the melt, while the temperature is carefully controlled to facilitate the growth of single crystals from a seed crystal. This process results in a large compound semiconductor wafer, at least two inches in diameter, with a low dislocation density of 5,000 cm, despite a low average zinc concentration.
