Abstract:
A method for forming a thin-film resistor on a semiconductor device, the semiconductor device having a semiconductor material and an isolation region formed on the semiconductor material, the method comprising the steps of:forming a layer of sacrificial material on the isolation region;removing a selected portion of the layer of sacrificial material to form an exposed portion of the isolation region; andforming a layer of resistive material over the exposed portion of the isolation region and the layer of sacrificial material, the layer of resistive material including a percentage by weight of silicon, a percentage by weight of carbon, and a percentage by weight of chromium, the percentage by weight of silicon ranging from 15-30%, the percentage by weight of carbon ranging from 10-20%, and the percentage by weight of chromium ranging from 50-70%.
