Latest Patents

One of his latest patents involves charged-particle-beam mapping projection-optical systems and methods for adjusting these systems. This innovation allows for quick and accurate adjustments in a typical system where an irradiation beam is emitted from a source. The beam passes through an irradiation-optical system and enters a Wien filter. After passing through the filter, the beam interacts with an object surface, generating an observation beam that returns to a detector. The system includes an adjustment-beam source that aids in aligning the object surface and optimizing the Wien's condition of the filter. The use of fiducial marks and evaluation charts further enhances the precision of these adjustments.
