S4. Plasma Science and Etching Technology

Thursday, February 6 | 1:00 pm - 5:30 pm

Ultra-fine Patterning Technology for EUV Era

The critical dimension of the semiconductor devices is decreasing to angstrom unit which contains only tens of atoms. For the precise control of the semiconductor device fabrication, various tools and methods including atomic layer deposition (ALD), atomic layer etching (ALE), cyclic etching, EUV lithography are becoming more essential in addition to conventional chemical vapor deposition (CVD), plasma etching, immersion ArF lithography, In addition, as the device size is decreased to deep subnanometer scale, the etch technology in becoming more important, and various materials which are difficult to etch are added in the material list to be etched by the evolution of various nonvolatile memory devices, and more selective and deeper etching with higher aspect ratio etching are required.  This year, in S4 session, as the continuation of last year, we focus on the topics related to diagnostic technique for next generation, new materials etching, etching technology for EUV era, and ALE. We invited the etch specialists from worldwide and we will try to provide the good chances to get the insight on the next generation etch technologies at this symposium. We hope that the coming symposium contribute to the expansion of the future technologies for overcoming the limitation on the next generation devices fabrication.
