Abstract
The present disclosure provides a semiconductor device with a copper-manganese liner and a method for preparing the semiconductor device. The semiconductor device includes a first well region and a second well region disposed in a semiconductor substrate. The semiconductor device also includes a first dielectric layer disposed over the semiconductor substrate and covering the first well region and the second well region, and a gate structure disposed over the first dielectric layer and between the first well region and the second well region. The semiconductor device further includes a conductive structure disposed over and separated from the first well region by a portion of the first dielectric layer. The conductive feature includes a barrier layer and a conductive plug disposed over the barrier layer, and the barrier layer is made of copper-manganese (CuMn). The first well region, the conductive structure and the portion of the first dielectric layer form an anti-fuse structure.
