Title: Yi-Hung Chen: Innovator in Light-Emitting Technology

Introduction

Yi-Hung Chen is a notable inventor based in Miaoli County, Taiwan. He has made significant contributions to the field of light-emitting devices, holding two patents that showcase his innovative approach to technology.

Latest Patents

His latest patents include a light-emitting diode and a manufacturing method thereof. This invention describes an LED that consists of a substrate, a light-tight reflective layer, an inner epitaxial layer, an outer epitaxial layer, a non-conducting layer, an ohmic metallic body, a first electrode, and a second electrode. The design features a separation space between the inner and outer epitaxial layers, which forms a closed path surrounding the light exit hole. This configuration effectively blocks electrical current and enhances light emission from the inner layer, resulting in a low side light ratio.

Another significant patent is for a light-emitting device and its manufacturing method. This device includes a base plate, a bonding metal layer, a conductive oxide layer, an epitaxial layer, an insulation layer, and multiple ohmic contact layers. The innovation lies in the use of a conductor line to connect the ohmic contact layer, eliminating the need for wire bonding. This advancement reduces the size of the light-emitting device and simplifies the packaging process, ultimately lowering fabrication costs and streamlining operations.
