ABSTRACT:
A method with wide process margins for producing a plated-wire memory elet with both good unipolar disturb resistance and burst read resistance. The method comprises adding the additional process step of dipping the wire after the first permalloy layer or a portion thereof has been plated into a bath of a chromium chloride solution so that a thin, discontinuous chromium chloride film overlays this inner permalloy layer. The rest of the first permalloy layer (mated-film process) or the second permalloy layer (mated-film process) may then be plated over this chromium chloride film.
