Title: Rocco A Orsini: Innovator in EUV Laser Technology
Introduction
Rocco A Orsini is a prominent inventor based in Long Beach, CA (US). He has made significant contributions to the field of laser technology, particularly in the development of extreme ultraviolet (EUV) radiation sources. With a total of 9 patents to his name, Orsini's work has advanced the capabilities of laser-plasma systems.
Latest Patents
Among his latest patents is the invention titled "Erosion reduction for EUV laser produced plasma target sources." This innovative laser-plasma EUV radiation source employs various approaches to prevent the vaporization of material from the nozzle assembly by electrical discharge from the plasma. One approach involves using an electrically isolating nozzle end, such as a glass capillary tube, which extends beyond the conductive surfaces of the nozzle assembly to minimize arcing. Another approach focuses on providing electrical isolation of the conductive portions of the source from the vacuum chamber wall. Additionally, applying a bias potential to the nozzle assembly raises its potential to match that of the arc.
Another notable patent is the "Droplet and filament target stabilizer for EUV source nozzles." This invention creates a stable solid target filament by utilizing a nozzle assembly with a condenser chamber that cryogenically cools a gaseous target material into a liquid state. The liquid target material is then forced through an orifice into an evaporation chamber, where it freezes into a stable target filament before being emitted into the process chamber.
