Patterned atomic layer etching and deposition using miniature-column charged particle beam arrays

Methods and systems for direct atomic layer etching and deposition on or in a substrate using charged particle beams. Electrostatically-deflected charged particle beam columns can be targeted in direct dependence on the design layout database to perform atomic layer etch and atomic layer deposition, expressing pattern with selected 3D-structure. Reducing the number of process steps in patterned atomic layer etch and deposition reduces manufacturing cycle time and increases yield by lowering the probability of defect introduction. Local gas and photon injectors and detectors are local to corresponding columns, and support superior, highly-configurable process execution and control.

Nanofabrication using a new class of electron beam induced surface processing techniques

Methods and systems for direct lithographic pattern definition based upon electron beam induced alteration of the surface chemistry of a substrate are described. The methods involve an initial chemical treatment for global definition of a specified surface chemistry (SC). Electron beam induced surface reactions between a gaseous precursor and the surface are then used to locally alter the SC. High resolution patterning of stable, specified surface chemistries upon a substrate can thus be achieved. The defined patterns can then be utilized for selective material deposition via methods which exploit the specificity of certain SC combinations or by differences in surface energy. It is possible to perform all steps in-situ without breaking vacuum.

Systems and methods for interferometric end point detection for a focused ion beam fabrication tool

Various technologies for providing an operator of a focused ion beam (FIB) system with navigational and processing data are described herein. An exemplary system includes a broadband light source and a narrowband light source that emit light to a target of the FIB. An optical detector receives reflections of the broadband light from the target and outputs data that is used to generate two-dimensional images of the target in a region near a location of incidence of the FIB at the target. An interferometer receives reflections of the narrowband light from the target and outputs data indicative of an interference pattern of the narrowband reflections. A computing device computes a thickness of one or more material layers that make up the target based upon the interference pattern. A two-dimensional image of the target and an indication of the computed thickness are then displayed to the operator of the FIB.
