    摘要: An improved process control for a charged beam system is provided that allows the capability of accurately producing complex two and three dimensional structures from a computer generated model in a material deposition process. The process control actively monitors the material deposition process and makes corrective adjustments as necessary to produce a pattern or structure that is within an acceptable tolerance range with little or no user intervention. The process control includes a data base containing information directed to properties of a specific pattern or structure and uses an algorithm to instruct the beam system during the material deposition process. Feedback through various means such as image recognition, chamber pressure readings, and EDS signal can be used to instruct the system to make automatic system modifications, such as, beam and gas parameters, or other modifications to the pattern during a material deposition run.

    摘要: A method for planning a beam path for material deposition is provided in which a structure pattern having features of varying size is analyzed to determine the size of each feature. A beam path throughout the structure pattern is determined and the beam current required for each point in the structure pattern is configured. Configuring the beam current required for each point involves determining the acceptable beam dose for that point. Relatively small features require a low beam current for high accuracy and relatively large features can be formed using a higher beam current allowing faster deposition. Each feature in the structure pattern is deposited at the highest beam current acceptable to allow accurate deposition of the feature.

    摘要: A method of modifying a sample surface layer in the vacuum chamber of a particle-optical apparatus, the method performed in vacuum, the method comprising: Providing the microscopic sample attached to a manipulator, Providing a first liquid at a first (controlled) temperature, Dipping the sample in the first liquid, thereby causing a sample surface modification, Removing the sample from the first liquid, Providing a second liquid at a second (controlled) temperature, Dipping the sample in the second liquid, and Removing the sample from the second liquid. This enables the wet processing of a sample in-situ, thereby enhancing speed and/or avoiding subsequent alteration/contamination of the sample, such as oxidation, etc. The method is particularly useful for etching a lamella after machining the lamella with a (gallium) FIB to remove the surface layer where gallium implantation occurred, or where the crystal lattice is disturbed.
