Abstract
A manufacturing method for a head slider coated with Diamond-like Carbon (DLC) includes: providing a substrate that is to be finally made into a head slider; depositing a DLC layer on a surface of the substrate, with carbon plasma source being sputtered in a direction that is vertical to the surface of the substrate; and doping a fluorine-doping (F-doping) layer on the DLC layer. Whereby the head slider has good film adhesion performance, higher hardness, better wear resistance, lower surface energy to obtain good hydrophobicity and oleophobicity, and lower fly height in HDD.
