Latest Patents

The latest patent awarded to Sang Y Lee is for a Laser Diode and Method for Fabricating the Same. This invention introduces a ridge waveguide laser diode featuring an inverse mesa structure that is not only heat resistant but also improves the adhesion of contact metal to the contact layer. By strategically forming a polyimide spacer, which remains only at the lower part of the corner of the inverse mesa structure, the contact metal is minimized from breaking off at the opposing sides of the mesa structure.

Another noteworthy patent by Lee is for the Electron Cyclotron Resonance Apparatus. This invention promises advanced cryogenic cooling effects and mitigates challenges commonly faced during the fabrication of next-generation integrated micropatterns. By utilizing the radioactive motion property of radicals, Lee’s apparatus successfully avoids side wall etching of photoresist. Furthermore, it addresses the conflicting increase or decrease phenomena observed in conventional etching equipment, achieving both desired vertical etching and a rapid etch rate, ultimately enhancing yield and productivity.
