Latest Patents

Ofer's latest patents include groundbreaking methods for high-resolution three-dimensional profiling of features in advanced semiconductor devices. One patent focuses on a non-destructive technique using electron beam scanning electron microscopy (SEM). This method involves obtaining a plurality of energy filter values through a model that simulates potential distribution within a 3D feature when an electron beam impinges on a selected area. By analyzing the simulated potential distribution, a correspondence is extracted between the energy filter values and respective depths of the 3D feature. This results in a composite 3D profile generated from various SEM images obtained from different depths.

Another patent addresses the use of electron beam scanning electron microscopy for characterizing a sidewall occluded from the line-of-sight of the electron beam. In this method, a semiconductor device is scanned by an electron beam while varying the energy value. The interaction with the sidewall is analyzed to determine whether it is occluded from the electron beam's line-of-sight. This innovative approach allows for the determination of the slope of the sidewall by comparing measured signals with simulated waveforms.
