Latest Patents
One of Okuyama's latest patents is a manufacturing method of a light-emitting device. This method includes a die-bonding process where a semiconductor light-emitting element is placed on a bonding target member using an adhesive containing a silicone resin. The adhesive is then heated to bond the semiconductor light-emitting element to the bonding target member. Additionally, a wire-bonding process is involved, where a wire is connected to the exposure surface of the semiconductor light-emitting element. This element features a laminated semiconductor layer with a light-emitting layer and an electrode made of a metal layer containing gold, covered by a layer of nickel or tantalum.
Another notable patent involves the production method of a Group III nitride semiconductor crystal. This method consists of two steps: the first step involves supplying a Group III raw material and a Group V raw material at a V/III ratio of 0 to 1,000 to form and grow a Group III nitride semiconductor on a heated substrate. The second step includes vapor-phase-growing a Group III nitride semiconductor crystal on the substrate using a Group III raw material and a nitrogen raw material.
