Articles capable of individual singulation

Abstract

A method of forming a glass article includes steps of: providing a glass substrate sheet, forming a first array of first damage regions, forming a second array of second damage regions which define a plurality of portions, wherein the second array of second damage regions define one or more interrupted zones. The interrupted zones may have a largest dimension of about 10 microns or greater. The method further includes steps of etching the glass substrate and singulating the plurality of portions from the glass substrate sheet.

What is claimed is: 
     
         1 . An article, comprising:
 a substrate sheet;   a first array of first damage regions which define a plurality of holes defined though the substrate sheet; and   a second array of second damage regions which define a plurality of second portions, wherein the second array of damage regions define one or more interrupted zones comprising a length of about 10 microns or greater.   
     
     
         2 . The article of  claim 1 , wherein the substrate is configured to singulate the second portions from the substrate along the second array of second damage regions. 
     
     
         3 . The article of  claim 1 , wherein the interrupted zones have a longest length dimension of about 100 microns or greater. 
     
     
         4 . The article of  claim 1 , wherein the second array of second damage regions comprise damage channels formed at an angle through the substrate sheet. 
     
     
         5 . The article of  claim 1 , wherein the second damage regions extend from a first surface of the substrate sheet to a second surface of the substrate sheet. 
     
     
         6 . The article of  claim 1 , wherein the substrate sheet comprises a glass, glass-ceramic, or ceramic material. 
     
     
         7 . The article of  claim 1 , wherein the second array of second damage regions comprises a plurality of interrupted zones.
