Method for manufacturing magnetoresistance head

A method for manufacturing a magnetoresistance head having at least one sense region formed in a stripe region, comprising the steps of:

• forming a multilayered film constituting a magnetoresistance device on an insulating nonmagnetic layer;
• forming an organic film of non-photosensitivity on said multilayered film;
• forming a resist film on said organic film;
• forming opening portions in said resist film on both sides of said stripe region by exposure and development of said resist film by a liquid developer which has larger velocity of dissolution of said organic film than that of said resist film to be remained by said development;
• forming a pattern of said organic film beneath said resist film by removing said organic film by said liquid developer through said opening portions succeedingly to said development of said resist film, an edge of said pattern of said organic film being cut inwardly from edges of a pattern of said resist film to such an extent that particles of thin film formed on said resist film in later step do not wrap around side portions of said pattern of said organic film;
• forming said thin film on said resist film and on said multilayered film beneath said opening portions;
• and
• patterning said thin film by peeling off said thin film with at least said resist film.
