Latest Patents

One of In-Jae Song's latest patents is a method of fabricating a freestanding GaN substrate. This innovative process involves preparing a GaN substrate within a reactor, treating its surface with HCl and NH gases to form a porous GaN layer, and subsequently creating a GaN crystal growth layer on top. The entire process is performed in-situ within a single reactor, significantly simplifying traditional methods. This approach not only reduces manufacturing costs but also allows for self-separation of thick GaN without cracking, leading to a high yield and short process time.

Another notable patent is the method of fabricating multi-freestanding GaN wafers. This method entails mounting a GaN substrate in a reactor, forming a GaN crystal growth layer, and processing the surface to create a GaN porous layer. By repeating these steps, a stack of alternating layers is formed, which self-separates upon cooling. This technique also emphasizes cost reduction and high-quality wafer production without cracks.
