Introduction

Man-Fang Huang is a notable inventor based in Hsinchu 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

Huang'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 by 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 serves as a bonding agent, and the bonded LED element is heated in a specialized wafer bonding tool. The 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 involves growing a light emitting region on a temporary substrate, but it bonds a transparent substrate of glass or quartz to the light emitting region. A metal bonding agent, which also functions as an ohmic contact layer, is used to bond the transparent substrate, forming a dual substrate LED element. Similar to the previous patent, this element is heated in a wafer holding device that includes a graphite lower chamber and a graphite upper cover, with a stainless steel screw applying pressure to assist in the bonding process.
