Abstract
A thin-film metal resistor (,) suitable for a multilayer printed circuit board (,), and a method for its fabrication. The resistor (,) generally has a multilayer construction, with the individual layers (,) of the resistor (,) being self-aligned with each other so that a negative mutual inductance is produced that very nearly cancels out the self-inductance of each resistor layer (,). As a result, the resistor (,) has a very low net parasitic inductance. In addition, the multilayer construction of the resistor (,) reduces the area of the circuit board (,) required to accommodate the resistor (,), and as a result reduces the problem of parasitic interactions with other circuit elements on other layers of the circuit board (,).
