The International Conference on Electron, Ion and Photon Beam Technology and Nanofabrication (EIPBN), affectionately known as "3-Beams," is the premier gathering of scientists and engineers who are dedicated to electron, ion and photon lithography, imaging, and analysis; atomically precise fabrication; nanofabrication process technologies and related emerging technologies; and their applications in a broad spectrum of fields. In its 64th meeting, researchers from academia, government laboratories, and industry from around the world meet to present and discuss recent and future trends in these technologies.

Width/depth and shape of volume of resist modified by ion beam as function of ion energy, exposure time and ion mass (He, Ne, Ar, Ga, Kr, Xe и Rn) is investigated by Monte-Carlo simulation. Sub-10nm resolution is found and confirmed. Analytical interpolating expressions for arbitrary ion mass, energy are submitted

 Ion beam lithography: resist modification volume determination and sub-10nm resolution prediction via simulation

In spite of M-C simulation shows strong dependence proximity function on depth (3D-PF)  it is possible to find effective α, β, η parameters for two-dimensional PF using original algorithm which considers development. Good agreement with experimental data is demonstrated thus proximity parameters now can be calculated for arbitrary layered material

PRESENTATION OF PROXIMITY FUNCTION BY THREE PARAMETERS , , BASED ON MONTE CARLO METHOD AND COMPARISON WITH EXPERIMENT

PMMA exposure sensitivity to both electrons and gallium ions at identical conditions was measured. It was found that a positive sensitivity to gallium ions is 1000 times higher than to electrons, all at the same conditions. Original procedure allowed to measure ion contrast (~3) for highly nonuniform in depth exposure

 Ion beam lithography: sensitivity/contrast in IBL vs EBL.

Our group used cellphone CMOS camera module, based on OV5648-BSI image sensor, to image 200keV electron beam in Transmission Electron Microscope and 30keV ion beam in Helium Ion Microscope.

Resonances in most of the metasurfaces are strongly depends on the geometry of the dielectric nanostructures and requires costly high-precision nanofabrication techniques. So we propose a robust structural symmetry-breaking silicon metasurface with ultra-narrow transparency.

Ultra-narrow Linewidth Symmetry-breaking Silicon Metasurface for Trace Biomolecules Sensing

we report the use of localized surface plasmon resonance (LSPR) sensor for real-time, label-free monitoring the adhering process of C. albicans onto the gold nanopillar array.  We also employ this sensor feature to elucidate how C. albicans’ adhesion is affected by different electrical properties of the material surface.

We present the fabrication of ion sliced lithium niobate on oxidized silicon for integrated optics. Using structural modeling to optimize wafer thicknesses and a bonding apparatus to match wafer bows, an 817 nm thick lithium niobate film on oxidized silicon is achieved over a centimeter scale area.

Stress reduction and wafer bow accommodation for the fabrication of thin film lithium niobate on oxidized silicon

We will discuss our use of ZnO nanoparticle-based thin films synthesized and grown at room temperature and deposited via electrophoretic deposition (EPD) onto p-doped silicon substrates.  Our experimentation plan includes using scanning electron microscopy to assess surface morphology and current-voltage characterization of ZnO/p-Si heterojunctions to study device performance potential.
