Claes H. Bjorkman,Yu Melissa Min,Hongquing Shan,David Cheung,Wai-Fan Yau,Kuo-Wei Liu,Nasreen Gazala Chopra,Gerald Zheyao Yin,Farhad Moghadam,Judy H. Huang,Dennis J. Yost,Betty Tang,Yunsang Kim +12 more
TL;DR: In this paper, a method of depositing and etching dielectric layers has been proposed for the formation of horizontal interconnects by varying the concentration of a carbon:oxygen gas such as carbon monoxide.
Patent
Counterbore dielectric plasma etch process particularly useful for dual damascene
Betty Tang,Jian Ding +1 more
TL;DR: A dielectric etch process particularly applicable to forming a dual-damascene interconnect structure by a counterbore process, in which a deep via is etched prior to the formation of a trench connecting two of more vias, is described in this article.
Patent
Plasma etch process in a single inter-level dielectric etch
Betty Tang,Jian Ding +1 more
TL;DR: A dielectric etch process applicable to forming a dual-damascene interconnect structure by a counterbore process, in which a deep via is etched prior to the formation of a trench connecting two of more vias as mentioned in this paper.

TL;DR: In this article, a method of depositing and etching dielectric layers having low Dielectric constants and etch rates that vary by at least 3:1 for formation of horizontal interconnects was proposed.

Understanding the evolution of trench profiles in the via-first dual damascene integration scheme
TL;DR: In this paper, an overview of the via-first dual damascene integration scheme is presented and several options for avoiding the evolution of fencing and faceting during the trench etch are proposed.
