Abstract :
The ArF photo resists are rapidly progressing just in time for the 0.1 μm device generation and beyond. There is a complex interaction between the lithographic performance and plasma etching process. This study develop a plasma etching process to etch dielectric hard mask with a commercial ArF resist and address the issue of limited etching resistance of the ArF resist.
