Publication number: 20250203885Abstract: Some implementations described herein provide a semiconductor device including a resistor structure. The resistor structure (e.g., a thin film resistor structure) includes a multi-layer film structure connecting contact structures of the resistor structure below the contact structures. The multi-layer film structure includes a capping layer, an upper resistive layer having a first concentration of silicon, and a lower resistive layer having a second concentration of silicon that is lesser relative to the first concentration.
