Patent ID: 7459097

Claim:
A method of forming a conductive pattern of a magnetic head, comprising: a first resist layer forming process that forms a first resist layer, which exposes formation positions of the conductive pattern, on a formation surface on which the conductive pattern is to be formed; a first stage conductive pattern forming process that forms a first stage conductive pattern by carrying out plating at the positions of the formation surface that are exposed from the first resist layer; a first resist layer removing process that removes the first resist layer; a first stage protective film covering process that forms a first stage protective film, which covers and protects the first stage conductive pattern, on the formation surface; a first stage grinding process that grinds flat a surface of the first stage protective film and end surfaces of the first stage conductive pattern to make the surface and the end surfaces flush; a second resist layer forming process that forms a second resist layer, which exposes parts of the end surfaces of the first stage conductive pattern more narrowly than the first stage conductive pattern, on the surface of the first stage protective film and the end surfaces of the first stage conductive pattern; a second stage conductive pattern forming process that forms a second stage conductive pattern by carrying out plating at the positions on the end surfaces of the first stage conductive pattern that are exposed from the second resist layer; a second resist layer removing process that removes the second resist layer; and a second stage protective film forming process that forms a second stage protective film, which surrounds and protects outer circumferential surfaces of the second stage conductive pattern, on the first stage protective film.
