Latest Patents
One of Freer's latest patents is titled "Method and system for growing a thin film using a gas cluster ion beam." This patent describes a method for forming a thin film on a substrate by providing a substrate in a reduced-pressure environment and generating a gas cluster ion beam (GCIB) from a pressurized gas mixture. The method involves setting a beam acceleration potential and a beam dose to achieve a thin film thickness of up to about 300 angstroms, with a surface roughness of less than about 20 angstroms. The GCIB is then accelerated and irradiated onto the substrate to grow the thin film effectively.
Another significant patent is the "Ion beam angle calibration and emittance measurement system for ribbon beams." This invention comprises a plate with an elongated slit positioned at the rotation center, allowing a first beam portion to pass through. It includes a beam current detector and a beam angle detector, collectively configured to rotate about the rotation center of the plate. This system is designed to measure beam currents accurately, enhancing the precision of ion beam applications.
