Title: Innovations of Chien-Chieh Lee
Introduction
Chien-Chieh Lee is a notable inventor based in Jhongli, Taiwan. He has made significant contributions to the field of light-emitting devices and micromachining technology. With a total of 2 patents, his work focuses on enhancing the performance and efficiency of LED devices and filters.
Latest Patents
One of his latest patents is titled "LED device having reduced spectrum." This invention presents a structure of light-emitting diode (LED) that effectively reduces its spectral width. The LED structure is applied in a three-color mixing of a backlight module to broaden the color space and improve the saturation of color displays. A grating structure is utilized as a waveguide layer to coordinate with the LED structure. Importantly, this invention does not affect the original thermal and electrical characteristics of the LED structure and features a simple fabrication method.
Another significant patent by Chien-Chieh Lee is the "Guided-mode resonance filter and fabrication method of same." This invention employs silicon bulk-micromachining technology to fabricate a GMR filter by utilizing the structure of a suspended silicon nitride (SiNx) membrane on a silicon substrate. A first silicon nitride (SiNx) thin film and a second silicon nitride (SiNx) thin film are formed on opposite sides of the silicon substrate. A first opening is defined in the first silicon nitride (SiNx) thin film, while a grating structure is defined in the second silicon nitride (SiNx) thin film. By etching off a portion of the silicon substrate exposed from the first opening until a portion of the second silicon nitride (SiNx) thin film is exposed, a light path space is defined.
