Latest Patents

Murray's latest patents include a method for cross-section sample preparation that involves attaching a prepared sample to a carrier in a focused ion beam chamber. This innovative method reduces the temperature within the chamber to substantially below room temperature, allowing for the establishment of cryogenic conditions. The attachment process utilizes a focused ion beam to sputter material onto both the base of the sample and the substrate carrier surface, effectively binding them together. Another patent focuses on a carrier grid with an integrated gas delivery system for use in charged particle beam systems. This carrier grid features an internal reservoir for gas storage and a post that supports the sample. By cutting the outlet tip near its base with a focused ion beam, the stored gas can escape, facilitating the attachment of the sample in the presence of the gas.
