Latest Patents

Kaneyama's latest patents include a Group III nitride compound semiconductor device featuring a superlattice structure. This innovative device utilizes a method where, after one of the layers constituting the superlattice structure is formed by an MOCVD method, NH gas is circulated together with H gas as a carrier gas to perform a purge step. Following this step, the next layer is formed. Another notable patent is for a Group III nitride compound semiconductor light-emitting device. This device includes a buffer layer of aluminum nitride (AlN) approximately 25 nm thick on a sapphire substrate. An n-layer of high carrier density, about 4.0 μm thick and made of GaN doped with silicon (Si), is formed on the buffer layer. An intermediate layer of non-doped InGaN is then created, followed by an n-type clad layer of GaN. The light-emitting layer is structured with two multilayer quantum well (MQW) cycles, enhancing its efficiency.
