Abstract

The present disclosure provides a semiconductor structure and a semiconductor device. The semiconductor structure includes a first conductive layer, a first barrier layer, and an insulating layer. The first conductive layer includes at least two traces, and a recess is formed between two adjacent ones of the traces. The first barrier layer is provided on a sidewall of the recess. The insulating layer fills the recess, and an air gap is formed in the insulating layer located in the recess.
