Latest Patents

Jun-sung Choi holds 1 patent for his invention titled "Method of fabricating GaN." This method involves creating a thick GaN layer by first forming a porous GaN layer with a thickness of 10-1000 nm. This is achieved by etching a GaN substrate in a reaction chamber under an HCl and NH3 gas atmosphere. The process allows for the in-situ growth of a GaN layer within the same chamber, simplifying the overall procedure compared to prior art. The use of an HVPE process gas for both etching and growth significantly reduces costs.
