Title: The Innovative Contributions of Michel Roche
Introduction
Michel Roche is a prominent inventor based in Dijon, France, known for his significant contributions to the field of electron technology and semiconductor processing. With a total of 12 patents to his name, Roche has made remarkable advancements that have implications in various technological applications.
Latest Patents
One of Roche's latest patents is for an electron gun with a focusing anode, designed for applications in irradiation and sterilization. This innovative electron gun features a sealed chamber under vacuum, where a cathode with an emitting face is positioned. The anode, which forms a sealed window, allows electrons emitted by the cathode to pass through. A biasing apparatus establishes a voltage between the anode and cathode, accelerating the electrons to form a focused beam. The curvature of both the anode and the emitting face is engineered to withstand pressure differences and to focus the electron beam effectively outside the chamber.
Another notable patent involves an apparatus for cutting thin layers from semiconductor materials. This device directs a pulse of energy into a substrate or ingot, where the pulse duration is carefully controlled to facilitate cleavage in a weakened zone. The apparatus ensures that the energy pulse is uniformly directed, allowing for precise cutting of thin layers essential for electronic, optoelectronic, or optical components.
