Abstract:
An apparatus generating a plasma for removing an edge polymer from a substrate is disclosed. The embodiment includes a powered electrode assembly, including a powered electrode, a first dielectric layer, and a first wire mesh disposed between the powered electrode and the first dielectric layer. The embodiment also includes a grounded electrode assembly disposed opposite the powered electrode assembly so as to form a cavity wherein the plasma is generated, the first wire mesh being shielded from the plasma by the first dielectric layer when the plasma is present in the cavity, the cavity having an outlet at one end for providing the plasma to remove the edge polymer.
Abstract:
AN APPARATUS, SYSTEM AND METHOD FOR CLEANING A SUBSTRATE EDGE (101) INCLUDE A BRISTLE BRUSH UNIT (200) THAT CLEANS BEVEL POLYMERS (103) DEPOSITED ON SUBSTRATE EDGES USING FRICTIONAL CONTACT IN THE PRESENCE OF CLEANING CHEMISTRY. THE BRISTLE BRUSH UNIT IS MADE UP OF A PLURALITY OF OUTWARDLY EXTENDING VANES (201) AND IS MOUNTED ON A ROTATING SHAFT (202). AN ABRASIVE MATERIAL IS DISTRIBUTED THROUGHOUT AND WITHIN THE OUTWARDLY EXTENDING VANES OF THE BRISTLE BRUSH UNIT TO PROVIDE THE FRICTIONAL CONTACT. THE BRISTLE BRUSH UNIT CLEANS THE EDGE OF THE SUBSTRATE BY ALLOWING FRICTIONAL CONTACT OF THE PLURALITY OF ABRASIVE PARTICLES WITH THE EDGE OF THE SUBSTRATE IN THE PRESENCE OF FLUIDS, SUCH AS CLEANING CHEMISTRY, TO CUT, RIP AND TEAR THE BEVEL POLYMER FROM THE EDGE OF THE SUBSTRATE.
