Title: Innovations of Sun-Chin Wei in Light Emitting Diodes
Introduction
Sun-Chin Wei is a notable inventor based in Tai-Nan Hsien, Taiwan. He has made significant contributions to the field of light emitting diodes (LEDs), holding two patents that showcase his innovative methods in manufacturing these essential components.
Latest Patents
Wei's latest patents include a "Light Emitting Diode with a Metal-Coated Reflective Permanent Substrate and the Method for Manufacturing the Same." This patent describes a method of manufacturing an LED that involves growing a light emitting region on a temporary substrate, bonding it to a metal-coated reflective permanent substrate, and subsequently removing the temporary substrate. The reflective metal layer also acts as a bonding agent, and the bonded LED element is heated in a specialized wafer bonding tool. This tool features a graphite lower chamber and a graphite upper cover, with a stainless steel screw that applies pressure during the heating process to enhance the bonding of the permanent substrate.
Another significant patent is the "Light Emitting Diode with a Permanent Substrate of Transparent Glass or Quartz and the Method for Manufacturing the Same." This method also begins with growing a light emitting region on a temporary substrate, followed by bonding a transparent substrate of glass or quartz to the light emitting region. A metal bonding agent serves as an ohmic contact layer, and the dual substrate LED element is heated in a wafer holding device similar to the previous method. The stainless steel screw again plays a crucial role in applying pressure during the heating process to assist in the bonding of the transparent substrate.
