Abstract
A metal resistor and a method for manufacturing the resistor are provided. A first insulation film is formed on a substrate, a photosensitive film is applied on the insulation film, and an insulation film pattern is formed by patterning the insulation film. After a metal thin film is formed among the insulation film pattern and on the photosensitive film, with removing the photo-sensitive film is a metal thin film pattern formed among the insulation film pattern. On the metal thin film pattern and the insulation film pattern is a second insulation film formed and at the pad region of the metal thin film pattern is a lead wire connected, after that, a metal thin film resistor is manufactured with forming a preservation film on and around the lead wire. Using a pattern-forming process by etching of the insulation film for forming the metal thin film pattern, the deterioration of the device or the lowering of the durability can be overcome, the resistance of the metal thin film resistor can be easily controlled, and the resolving power can be improved by producing the high-resistance metal thin film temperature having reduced line with of the metal thin film pattern.
