titleOfInvention Method for manufacturing semiconductor device
abstract The present disclosure provides a method of manufacturing a semiconductor device. A method of manufacturing a semiconductor device includes: forming grooves in a first dielectric layer on a substrate, the first dielectric layer including first portions between the grooves; forming a first barrier layer and an interconnection layer in each groove; recessing the interconnect layer and the first barrier layer; forming a blanket pattern on the recessed interconnect layer; etching at least a portion of the first portion by a first etching process; continuing to etch the overlay pattern and at least a portion of the first portion by a second etch process to form a trench; conformally forming a second barrier layer in the trench and on the recessed interconnect layer; and forming a second dielectric layer on the second barrier layer without filling the trench such that an air gap is formed in the trench.
