Latest Patents

One of his latest patents is titled "Nitride semiconductor light-emitting element and method for fabricating the same." This invention discloses a nitride semiconductor light-emitting element that features an n-type AlGaN cladding layer grown on a GaN substrate. An InGaN active layer of a quantum well structure is then grown on this cladding layer at a temperature of about 800°C or less. Following this, a buffer layer of GaN, AlGaN, or InGaN is grown on the InGaN active layer at a temperature of about 900°C or less. The process continues with the growth of a p-type AlGaN cladding layer and a p-type GaN electrode layer. This innovative method results in a nitride semiconductor light-emitting element with high optical and thermal efficiency.

Another notable patent is for a "GaN system compound semiconductor and method for growing crystal thereof." This invention addresses the reduction of crystalline defects caused by lattice mismatch. It involves growing a GaN system compound semiconductor using an InAlN crystal as an intermediate buffer layer on a sapphire substrate. The method includes providing a sapphire substrate, growing an intermediate buffer layer of InAlN, and subsequently growing the GaN or InGaN system compound semiconductor.
