Claim Text:
1. An electronic component manufacturing method, comprising: forming a first electrode constituting layer in a recess formed in a workpiece, the recess having an opening diameter of 15 nm or less; performing plasma nitridation directly on a surface of the first electrode constituting layer; and forming a second electrode constituting layer free of Ti directly contacting the first electrode constituting layer, which has been subjected to the plasma nitridation, wherein in the forming of the first electrode constituting layer, the first electrode constituting layer is formed by sputtering while a magnetic field is formed on a target surface by a magnet unit having a plurality of magnets disposed at grid points of a polygonal grid arranged in a grid, the magnets being disposed such that adjacent magnets have opposite poles, wherein the plasma nitridation is performed while a magnetic field is formed on the target surface by the magnet unit, and wherein in the forming of the second electrode constituting layer, the second electrode constituting layer having a flat surface is formed by sputtering while a magnetic field is formed on the target surface by the magnet unit.
