Latest Patents

Horikoshi's latest patents include a method for forming thin films of compound semiconductors by flow rate and a preparation process of compound semiconductors. In his patented method, a compound semiconductor thin film is formed by growing multiple molecular layers one over another. The process involves the normal flow of a carrier gas and a small quantity of hydride containing an element from Group V or VI. An organometallic compound, diluted with hydrogen and containing an element from Group III or II, is alternately introduced over a substrate. This allows for the growth of atomic layers of elements from Group III or II and Group V or VI. The method results in layers with a high degree of purity and enables high-concentration doping of III-V compound semiconductors. This innovation is particularly advantageous for the fabrication of high-speed FETs and multi-quantum-well lasers.
