Abstract:

The present disclosure provides a method for fabricating an integrated circuit. The method includes forming an energy removable film (ERF) on a substrate; forming a first dielectric layer on the ERF; patterning the ERF and first dielectric layer to form a trench in the ERF and the first dielectric layer; filling a conductive material in the trench; forming a ceiling layer on the first dielectric layer and conductive material filled in the trench; and applying energy to the ERF to form air gaps in the ERF after the forming of the ceiling layer.

Abstract(Chinese):

本公开提供了一种用于制造集成电路的方法。该方法包括在基板上形成能量可去除膜（ERF）; 在ERF上形成第一介电层; 图案化ERF和第一介电层以在ERF和第一介电层中形成沟槽; 在沟槽中填充导电材料; 在第一介电层上形成顶层和填充在沟槽中的导电材料; 并且在形成天花板层之后，向ERF施加能量以在ERF中形成气隙。
