硅基AlGaN紫外大功率LED外延、芯片与封装的专利分析

Patent Analysis of Silicon-based AlGaN UV High Power Epitaxy, Chip and Package

UV-LEDs具有高效可靠等特点,在照明、水和空气净化以及紫外光刻等方面的广泛应用,也逐渐引起人们越来越多的关注。各国LED企业纷纷加大研发力度及知识产权布局保护。本文对中国、美国和欧洲地区的硅基AlGaN外延、芯片与封装方面的专利技术发展现状展开研究,并对专利申请量、IPC分类号以及重要专利权人进行剖析,从而分析出硅基AlGaN专利技术竞争热度以及知识产权竞争状况,以便于指导国内LED企业在硅基AlGaN器件专利的布局。

Considering that UV-LEDs are of high efficiency and reliability,they have been widely used in many aspects,such as,lighting,water and air purification,ultraviolet lithography and so on,and have attracted more and more attention.Therefore,LED enterprises in various countries have put increased effort in products research and development together with intellectual property.This paper aims to study the patent technology development status of China,America and Europe by analyzing Silicon-based AlGaN epitaxy,chip and package,and analyzes the number of patent applications,IPC classification numbers and important patent holders.Thereby,the competition heat of silicon-based AlGaN patented technology and the competition situation of intellectual property rights are analyzed,in order to guide the domestic LED enterprise’s patent layout in silicon-based AlGaN devices.
