Abstract
The present disclosure provides a semiconductor device structure with a fluorine-catching layer. The semiconductor device structure includes a first dielectric layer disposed over a semiconductor substrate, and a second dielectric layer disposed over the first dielectric layer. The semiconductor device structure also includes a fluorine-catching layer disposed over the second dielectric layer, and a third dielectric layer disposed over the fluorine-catching layer. The semiconductor device structure further includes a conductive via structure penetrating through the third dielectric layer, the fluorine-catching layer, and the second dielectric layer to contact the first dielectric layer.
