This seminar will highlight the newly installed Elionix ELS-G100 Electron Beam Lithography System to the Marcus Inorganic Cleanroom. Attendees will receive a general introduction to e-beam lithography, i.e. direct-writing of user-defined CAD patterns with a beam of high-energy electrons. Additionally, the speaker will walk you through some of the advanced e-beamlithographytopics by using Elionix ELS-G100 as a model system.

Seminar Topics

• E-beam system configuration and its components
• Principles of operation for ebeam exposure
• Limits of e-beam and its implications
• Proximity effect in ebeam exposure
•  Effect of post-exposure processing

Tool Specifications

• Generates patterns with a line width of 6nm with an 8” stage
• Stable 1.8nm electron beam using high beam current at 100kV
• 20bit DAC provides high beam positioning resolution
• At a beam current of 1nA, 20nm lines can be written over an entire
• 500μm field without stitching

Speaker: Yong Sun - A dedicated and driven scientist by training, with 15 years of hands-on nanofabrication experience in the semiconductor field, Yong has worked
both in academia and in industry, with research interests spanning across a varietyof subjects, including sensors, microfluidics, metamaterials, Li-Ion battery and energy
converters, to name a few. I am currently the Product Manager at SEMTech Solutions, collaborating with a group of dedicated engineers to advance the Elionix e-beam technology. Before joining the Elionix team, I have worked as a cleanroom manager at Princeton University, teaching users on the operation of many lithography tools,including Elionix ELS-F125.
