Title: Mostafa Maazouz: Innovator in Charged-Particle Beam Technology
Introduction
Mostafa Maazouz is a prominent inventor based in Hillsboro, OR (US). He has made significant contributions to the field of charged-particle beam technology, holding a total of 12 patents. His innovative work has advanced the understanding and application of liquid metal ion sources and focused ion beams.
Latest Patents
Among his latest patents, one notable invention is the method for determining the virtual source location of a liquid metal ion source. This method involves scanning an alignment aperture that is fixed with respect to a beam defining aperture in a charged-particle beam (CPB). The alignment aperture transmits a CPB portion to a secondary emission surface, which produces secondary emissions directed to a scintillator element. The scintillation light generated is then directed out of a vacuum enclosure associated with the CPB via a light guide to an external photodetection system.
Another significant patent focuses on optical alignment correction using convolutional neural network evaluation of a beam image. In this invention, a focused ion beam (FIB) is utilized to mill beam spots into a substrate at various ion beam column settings. This process creates a set of training images used to train a convolutional neural network. Once trained, the neural network can adjust the ion beam by processing spot images and providing necessary adjustments for optimal performance.
