Abstract

Embodiments include a method for processing thin substrates. Embodiments may include electrostatically bonding a substrate to a first electrostatic carrier (ESC), with a backside of the substrate is facing away from the first ESC. Thereafter, the substrate may be thinned to form a thinned substrate. The thinned substrate may then be transferred to a second ESC with a front side of the thinned substrate facing away from the second ESC. Embodiments may include cleaning the front side surface of the thinned substrate and transferring the thinned substrate to a third ESC. In an embodiment, a backside of the thinned substrate is facing away from the third ESC. Embodiments may also include processing the backside surface of the thinned substrate, and transferring the thinned substrate to a tape frame.
