FABRICATION OF BIT PATTERNED MEDIA USING MICROCONTACT PRINTING

摘要

A method for manufacturing a bit patterned magnetic media for magnetic data recording. The method includes selectively depositing a self assembled monolayer over a seed layer and then oxidizing the deposited self assembled monolayer. The self-assembled monolayer can be deposited by use of a stamp to form a pattern covering areas where a non-magnetic segregant (such as an oxide) is to be formed and openings where a magnetic material is to be formed. A magnetic alloy and a segregant (such as an oxide) are then co-sputtered. The magnetic alloy grows only or selectively over the seed layer, whereas the segregant grows only or selectively over the oxidized self-assembled monolayer.

1. A method for manufacturing a magnetic media, comprising:
depositing a seed layer; forming a stamp having a pattern formed thereon; coating the stamp with a segregant promoter; placing the stamp against the seed layer so as to selectively print the segregant promoter onto the seed layer; and performing a co-sputtering of a magnetic material and a segregant.
