摘要:
A method is disclosed for producing sliders with protective contacts features the fabrication of which is initiated at the wafer level. Recesses are formed in the wafer, a protective material is provided in the recesses, and the wafer is sliced along the recesses and diced into sliders, such that the protective material forms corners of the sliders. The protective material may be disposed such that it has a low elastic modulus at the corners, and a higher elastic modulus at a displacement from the corners which is still lower than the elastic modulus of the slider body, thereby providing superior protection for potential contacts between the slider and an adjacent media surface.
