Low-k interconnect structures with reduced RC delay

Abstract:

A method for forming an integrated circuit includes forming a low-k dielectric layer over a semiconductor substrate, etching the low-k dielectric layer to form an opening, forming a dielectric barrier layer covering at least sidewalls of the opening, performing a treatment to improve a wetting ability of the dielectric barrier layer, and filling the opening with a conductive material, wherein the conductive material is in contact with the dielectric barrier layer.

Abstract(Chinese):

一种用于形成集成电路的方法包括在半导体衬底上形成低k电介质层，蚀刻低k电介质层以形成开口，形成至少覆盖开口侧壁的介电阻挡层，进行处理以改善介电阻挡层的润湿能力，并用导电材料填充开口，其中导电材料与电介质阻挡层接触。
