Publication number: 20240363529Abstract: Some implementations described herein include a semiconductor device including a semiconductor resistor structure having and techniques for forming the semiconductor resistor structure. The techniques include forming a layer of a silicon chromium material having different silicon/chromium ratios within the layer (e.g., a graded resistive layer) as part of forming the semiconductor resistor structure. The graded resistive layer may compensate for semiconductor manufacturing processes (e.g., etching, oxidation, thermal annealing) that may lead to film damage, thinning, crystallization, or composition drift of the graded resistive layer to enlarge process windows for fabricating the semiconductor resistor structure. The enlarged process window may improve a performance of the semiconductor resistor structure (e.g., a resistance and/or an impedance uniformity) relative to another semiconductor resistor structure fabricated using a uniform layer of a silicon chromium material.Type: ApplicationFiled: April 27, 2023Publication date: October 31, 2024Inventors: Chun-Heng CHEN, Hsin-Li CHENG, Ru-Shang HSIAO, Shih-Fen HUANG, Tuo-Hsin CHIEN, Yu-Wei LIANG
