Title: Fu-Chou Liu: Innovator in Semiconductor Technology

Introduction

Fu-Chou Liu is a prominent inventor based in Hsinchu, Taiwan. He has made significant contributions to the field of semiconductor technology, particularly in the development of light-emitting devices. With a total of 3 patents to his name, Liu's work has advanced the efficiency and functionality of light-emitting diodes (LEDs) and laser diodes (LDs).

Latest Patents

One of Liu's latest patents is a semiconductor light-emitting device with a conductive window layer. This innovative device features a structure where the light-emitting area is either a double heterostructure or a multi-layer quantum well structure. The light-emitting area is formed on a substrate, and an electrically conductive oxide layer serves as a transparent window layer to eliminate the crowding effect. The substrate consists of a GaAs substrate and a GaAsP layer, which increases the band gap energy of the substrate. The oxide layer is made from AlZnO(x) material, known for its lower electrical resistivity and high transparency in the visible wavelength region. The window layer is created using physical vapor deposition or metalorganic chemical vapor deposition techniques.

Another notable patent by Liu is a light-emitting diode with an anti-reflector. This design includes a semiconductor substrate of a first conductivity type, with a first electrode formed on part of the substrate. A reflection stack of the first conductivity type is built on the substrate, followed by an active layer on the reflection stack. An anti-reflection stack of a second conductivity type is then grown on the active layer, consisting of multiple layers with specific thicknesses. A window layer of the second conductivity type is formed on the anti-reflection stack, culminating in the formation of a second electrode on part of the window layer.
