Abstract: As semiconductor technology node continuously shrinks, Wet strip process works as a more important role beyond 45m. For RC delay concern, Ultra Low-K material is introduced to BEOL ILD (Interlayer Dielectric). After Trench First Metal Hard Mask All-in-One Etch, ULK film sidewalls are exposed during Wet strip. In semiconductor Back-End-of-Line (BEOL) processing, wet organic strippers have gained a renewed interest for removal of etched photoresist (PR) layers to replace plasma strip, which degrades porous low-k dielectrics. In this study we show how the characterization of nm PR degradation by etch plasmas led to the. About Us · Careers · News · Contact Us · Login · Register · Visit our YouTube Channel.

Microelectronic Engineering VolumeMayPages Abstract In semiconductor Back-End-of-Line BEOL processing, wet organic strippers have gained a renewed interest for removal of etched photoresist PR layers to replace plasma strip, which degrades porous low- k dielectrics. In this study we show how the characterization of nm PR degradation ass trans etch plasmas led to the development of an environment friendly wet strip using aqueous ozone solutions.
