Title: Ray-Hua Horng: Innovator in Light Emitting Diode Technology
Introduction
Ray-Hua Horng is a prominent inventor based in Chang-Hua Hsien, Taiwan. He has made significant contributions to the field of light emitting diodes (LEDs), holding three patents that showcase his innovative methods in manufacturing LED technology. His work has had a substantial impact on the efficiency and effectiveness of LED applications.
Latest Patents
Horng's latest patents include a method for manufacturing a light emitting diode with a metal-coated reflective permanent substrate. This method 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 serves as a bonding agent, and the bonded LED element is heated in a specialized wafer bonding tool. This process utilizes the different thermal expansion coefficients of materials to enhance the bonding of the permanent substrate.
Another notable patent is for a light emitting diode with a permanent substrate made of transparent glass or quartz. This method also begins with growing a light emitting region on a temporary substrate, followed by bonding a transparent substrate to the light emitting region. A metal bonding agent is used to create an ohmic contact layer, forming a dual substrate LED element. Similar to his previous patent, this element is heated in a wafer holding device to assist in the bonding process.
