Abstract
A mechanically releasable slider process utilizes silicone rubber or PDMS to take the function of a planarization material for individual sliders or slider rows. Mechanical debonding takes advantage of the rubber-elastic property of PDMS. A gripper is used in a virtually solvent-free, air bearing patterning UV-molding process and resist-based processes. A PDMS-based fixture is used during both the lapping process and the photo or UV-mold patterning of the ABS surface. This fixture can mechanically hold sliders by large area reversible adhesion while allowing gimbaling, electrical connection, actuation, UV-molding or photolithography, and mechanical release, thus reducing the number of slider manipulations to two.
