PPT-Electron-beam lithography

with the Raith EBPG Part 1 Introduction M Rooks Yale University The EBPG has a long history stretching back to the 1960s This particular ebeam system was first built by Philips in the Netherlands then was bought out by Cambridge Instruments UK which morphed into Leica Lithography spun off as . Michael Johnston. 4/13/2015. Abstract and Outline. Nanoscale Lithography. . is an ever growing fabrication process due to technology demands. We are continuously striving to increase the number of transistors on a chip to increase performance. The drive for smaller and faster technologies has caused the development of fabrication techniques that allow us to work at the nanoscale feature size. A few lithography techniques will be explored to show how this whole process works. The processes I will cover include Photo, Electron Beam and X-Ray lithography. These forms of lithography share a common process of preparation exposure and development while fabricating wafers.. NANO 101. Introduction to Nanotechnology. 1. 2. Lithography. Photolithography.

Overview and resolution limit.. Electron source (thermionic and field emission).. Electron optics (electrostatic and magnetic lens).. Aberrations (spherical, chromatic, diffraction, astigmation).. EBL systems (raster/vector scan, round/shaped beam). Introduction.. Photon-based lithography: DUV (deep UV), EUV (extreme UV), X-ray. Charged-beam based lithography: electron beam, focused ion beam. Nanofabrication by molding/printing: soft lithography, nanoimprint. Electron Beam Lithography System - ELF 10000 Electron Beam Lithography System HS50 University of Illinois Urbana-Champaign to Install First 150kV Electron Beam Lithography System in North America Harvard’s Center for Nanoscale Systems(CNS) will install North America’s first High Speed Elionix ELS-HS50 electron beam lithography system. This will be the third Elionix electron beam lithography system installed into the Harvard CNS cleanroom. Nanoscale fabrication techniques have taken device, systems and material design to a new level. Electron Beam Lithography (EBL) enables the creation of highly accurate nanoscale structures. SEMTech Solutions, in partnership with Elionix, is pleased to announce the order of a 100kV Electron Beam Lithography (EBL) system to the Norwegian University of Science and Technology (NTNU).
