Latest Patents

One of Baek's latest patents is titled "Real time epitaxial growth of vertical cavity surface-emitting laser using a reflectometry." This method involves the use of a main measuring laser that shares the same wavelength as the VCSEL. By analyzing the reflected signal, it estimates the growth periods required for the material layers, thus eliminating the need for prior knowledge of refractive indexes and growth speeds. This approach allows for in-situ epitaxial growth, improving reproducibility and uniformity. Additionally, a subsidiary measuring laser can be employed to enhance the accuracy of growth time control.

Another notable patent is the "Method for sensing etch of distributed Bragg reflector in real time." This method monitors the etching process during semiconductor device manufacturing. By irradiating a laser beam on the sample submerged in etching solution, the intensity of the reflected laser is measured to determine the etching speed in real time. This innovative technique ensures uniform etching across the entire sample, which is crucial for the quality of semiconductor devices.
