Title: Innovations of Cliff Knollenberg
Introduction
Cliff Knollenberg is a notable inventor based in Mountain View, CA (US). He has made significant contributions to the field of semiconductor technology, particularly in the development of light-emitting structures. With a total of 3 patents to his name, Knollenberg's work has advanced the capabilities of deep ultraviolet light-emitting diodes.
Latest Patents
One of his latest patents is titled "Light emitting structure including high-al content MQWH." This invention involves a GaN/AlN superlattice formed over a GaN/sapphire template structure. This superlattice serves as a strain relief layer for the growth of subsequent layers, such as deep UV light-emitting diodes. The GaN/AlN superlattice effectively mitigates the strain between the GaN/sapphire template and a multiple quantum well heterostructure active region. This innovation allows for the use of a high Al mole fraction in the active region, enabling emission in deep UV wavelengths.
Another significant patent by Knollenberg is "Method of manufacturing a semiconductor device including a superlattice strain relief layer." Similar to his previous patent, this invention also utilizes a GaN/AlN superlattice over a GaN/sapphire template structure. It serves the same purpose of strain relief for the growth of subsequent layers, enhancing the performance of deep UV light-emitting diodes.
