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.

Claim (Index 19):
A method for processing a thin substrate, comprising:\n aligning a substrate and an electrostatic carrier (ESC) with a notch aligner; preconditioning the ESC, wherein preconditioning the ESC includes one or more of a baking process, a cooling process, and a vacuum purge process; aligning the substrate to the ESC, wherein a center of the substrate is within approximately +/\u221240 \u03bcm of a center of the ESC electrostatically bonding the substrate to the ESC, wherein the ESC includes purge holes, and wherein electrostatically bonding the substrate to the ESC includes vacuum coupling the substrate to the ESC prior to initiating the electrostatic bond between the substrate and the ESC; thinning the substrate to form a thinned substrate; processing the thinned substrate, wherein the thinned substrate remains attached to the ESC during the processing of the thinned substrate, and wherein the processing comprises one or more of an etching process, a cleaning process, and a deposition process; and transferring the thinned substrate to a tape frame, wherein transferring the substrate to the tape frame comprises:\n releasing the electrostatic charge from the ESC; and \n applying a purge gas between the surfaces of the ESC and the substrate prior to mechanically separating the ESC from the substrate.
