PPPL scientist uncovers physics behind plasma-etching process

27 Jan 2017 Plainsboro - Physicist Igor Kaganovich at the Department of Energy's (DOE) Princeton Plasma Physics Laboratory (PPPL) and collaborators have uncovered some of the physics that make possible the etching of silicon computer chips, which power cell phones, computers, and a huge range of electronic devices. Specifically, the team found how electrically charged gas known as plasma makes the etching process more effective than it would otherwise be. The research, published in two papers appearing in the September and December 2016 issues ofPhysics of Plasmas, was supported by the DOE's Office of Science (FES).

Igor Kaganovich, Deputy Head of the PPPL Theory Department, together with Dmytro Sydorenko of the University of Alberta, knew that the plasma etching process was effective, but were not sure exactly how the process worked. So they investigated the process's theoretical underpinnings.

During the etching process, a piece of silicon is placed in a chamber and immersed within a thin layer of plasma, about two centimeters wide. Also within the plasma are two electrodes spaced a couple of centimeters apart that produce a beam of electrons. As the electrons flow through the plasma, they start a process known as a two-stream instability, which excites plasma waves that enable the plasma to etch the silicon more efficiently.

Dmytro Sydorenko and Igor Kaganovich modelled this process. They showed that the waves created by the electron beam can become much more intense than in plasmas that are not bounded by electrodes. In other words, when a plasma is bounded, the wave driven by the two-stream instability can become very strong. "The simulations indicate that the placing of plasma within a pair of electrodes supports the excitation of large plasma waves, which then lead to the acceleration of plasma electrons that can aid etching", Igor Kaganovich stated.

Understanding the physics undergirding the plasma etching technique could help researchers design more efficient processes to etch circuits on silicon chips.

PPPL, on Princeton University's Forrestal Campus in Plainsboro, New Jersey, is devoted to creating new knowledge about the physics of plasmas - ultra-hot, charged gases - and to developing practical solutions for the creation of fusion energy. The Laboratory is managed by the University for the U.S. Department of Energy's Office of Science, which is the largest single supporter of basic research in the physical sciences in the United States, and is working to address some of the most pressing challenges of our time.
