| 摘要 |
The present invention makes it possible to manufacture a slider having two surfaces at different depths relative to a flying surface.First etching is performed to form a second surface corresponding to a step portion using a photoresist mask; thereafter, another photoresist mask is formed on a region to become a second surface of the slider bar without removing the former photoresist mask; and second etching is performed using those photoresist masks to form a third surface corresponding to a negative pressure generating portion.
