Title:
RESISTOR, VARIABLE RESISTOR, AND METHOD FOR MANUFACTURING RESISTOR
Document Type and Number:
WIPO Patent Application WO/2022/202808
Kind Code:
A1
Abstract:
With a resistor, a variable resistor, and a method for manufacturing a resistor according to the present invention, it is possible to eliminate lead and prevent deterioration of sliding characteristics. A resistor according to the present invention is disposed on an insulating layer. The resistor has: a more-conductive-material-containing layer containing more conductive materials than insulating materials; and a more-insulating-material-containing layer that does not contain lead and that contains more insulating materials than conductive materials. The more-conductive-material-containing layer has a polished surface. For example, the film thickness of the more-conductive-material-containing layer in a low-resistance region having a resistance value smaller than or equal to a prescribed value is larger than the film thickness of the more-insulating-material-containing layer in a high-resistance region having a resistance value larger than the prescribed value.
