Title: Edmund Harold Linfield: Innovator in Laser Technology and Semiconductor Processing
Introduction
Edmund Harold Linfield is a distinguished inventor based in Cambridge, GB. He has made significant contributions to the fields of laser technology and semiconductor processing, holding a total of 7 patents. His innovative work has advanced the understanding and application of lasers in various scientific and industrial contexts.
Latest Patents
One of Linfield's latest patents is a laser system for imaging and materials analysis. This invention utilizes a THz quantum cascade laser to investigate a target by directing a first beam of laser radiation at it. The interaction between the first beam and the target produces a second beam of laser radiation. The self-mixing of these beams within the laser leads to variations in a signal, such as the operating voltage of the laser. By monitoring and processing these variations, the invention allows for the production of various images of the target, revealing material properties.
Another notable patent involves the removal of oxide from semiconductor surfaces using a flux of indium atoms. This method entails arranging a semiconductor body in a vacuum chamber while maintaining its temperature within a predetermined range. The surface is then exposed to a flux of indium atoms, effectively removing at least one oxide. This process prepares the surface for the epitaxial growth of layers or films, contributing to the manufacturing of semiconductor devices.
