A new approach combining atomic layer deposition and organic film etch process may solve critical challenges in the various processes in advanced nodes. We demonstrated a high selective and ...
The process comprises a surface nitrogenation step via N + ion bombardment, followed by O 2 plasma treatment to form volatile etching byproducts. This approach enables subatomic-level etching ...
In dry etching, the trajectory of accelerated ions is non-uniform and non-vertical, due to collisions with gas molecules and other random thermal effects (figure 1). This has an impact on etch results ...
