Abstract: A bar mask for row bar processing includes at least a slider cover and at least a groove cover arranged adjacent to the slider cover. The groove cover is transparent, and the slider cover is opaque. The slider cover has two extending portions and an ABS portion arranged therebetween with some transparent patterns formed on the ABS portion. The ABS portion covers a single row bar, and the two extending portions each cover a row bar adjacent to the single row bar.

Abstract: A method of row bar for manufacturing slider includes steps: providing a plurality of row bars arranged in rows, with each row bar having slider regions and bar grooves adjacent to the slider region; providing photoresist on the row bar; providing a bar mask, having slider cover and groove cover which is transparent, the slider cover having two extending portions and a ABS portion arranged therebetween with some transparent patterns formed thereon; arranging the ABS portion on the slider region of the third said row bar, with two extending portion being covered respectively on the slider region of the second row bar and the fourth row bar, then exposing the bar mask to the light, the bar groove being exposed to the light via the groove cover; carrying out the above step until the ABS portions are arranged on the last row bar; developing and etching the row bars.
