Abstract
A method for manufacturing a resistor function in an electric conductor on the surface of a carrier, preferably a conductor on printed circuit boards, substrates and chips. By etching using an anisotropic etching technique, the conductor is provided with at least one portion which has a smaller cross-sectional area than the conductor surrounding the portion, the length and width of the portion being such that a predetermined resistance is obtained in the conductor. A resistor according to the invention is on both sides connected to a conductor on a carrier, such as a printed circuit board, a substrate or a chip. The resistor comprises a conductor portion positioned on the carrier and having a significantly smaller cross-sectional area than the conductor on both sides of the resistor.
