Johns Hopkins Team Unveils Wafer-Scale Metal-Organic Resists for Beyond‑EUV Chipmaking

The peer‑reviewed study demonstrates chemical liquid deposition of imidazole films with nanometer control.

Overview

  • Researchers report that imidazole-based metal‑organic resists can be deposited from solution across silicon wafers using a chemical liquid deposition process.
  • The materials are engineered to interact strongly with beyond‑extreme‑ultraviolet radiation, with metals such as zinc absorbing photons and generating electrons that drive the required chemistry.
  • The approach targets features smaller than today’s ~10‑nanometer standard by pairing metal absorbers with tunable organic components.
  • The team describes the platform as precise and economical for production and says B‑EUV use in manufacturing is expected within roughly the next decade.
  • Findings published in Nature Chemical Engineering detail a multi‑institution effort spanning Johns Hopkins, ECUST, EPFL, Soochow University, Brookhaven, and Lawrence Berkeley National Laboratories.
