Abstract
A method for fabricating a magnetic recording transducer is described. The magnetic recording transducer has an underlayer and at least one layer on the underlayer. The layer(s) are capable of including an aperture that exposes a portion of the underlayer. The method includes providing a neutralized aqueous solution having a chemical buffer therein. The chemical buffer forms a nonionic full film corrosion inhibitor. The method also includes exposing a portion of the magnetic recording transducer including the layer(s) to the neutralized aqueous solution including the chemical buffer. In one aspect this exposure occurs through a chemical mechanical planarization.
