1. A method of implanting a workpiece comprising:implanting a first species into an entire surface of said workpiece, wherein said first species has a dose that is uniform across said entire surface of said workpiece;implanting helium into said entire surface of said workpiece, wherein said helium has a non-uniform dose such that said helium has a higher dose at a portion of a periphery of said workpiece; andinitiating a split of said workpiece at said portion of said periphery with said higher dose. 2. The method of claim 1, wherein the first species is selected from the group consisting of hydrogen, helium, and nitrogen. 3. The method of claim 1, wherein said portion is less than 360° of said periphery of said workpiece. 4. The method of claim 1, wherein said initiating uses at least one of a thermal process or a mechanical process. 5. The method of claim 1, wherein said non-uniform dose is caused by altering at least one of a scan speed of said workpiece and an ion beam current of said helium. 6. The method of claim 1, wherein said portion of said periphery has a dose of said helium at least 20% larger than a remainder of said workpiece. 7. The method of claim 1, wherein said implanting said first species and said implanting said helium are performed sequentially without breaking a vacuum. 8. A method of implanting a workpiece comprising:implanting a uniform dose of hydrogen into said workpiece;implanting a non-uniform dose of helium into said workpiece by altering at least one of a scan speed of said workpiece and an ion beam current of said helium, wherein said helium has a higher dose at a portion of a periphery of said workpiece; andinitiating a split of said workpiece at said portion of said periphery with said higher dose. 9. The method of claim 8, wherein said portion is less than 360° of said periphery of said workpiece. 10. The method of claim 8, wherein said initiating uses at least one of a thermal process or a mechanical process. 11. The method of claim 8, wherein said portion of said periphery has a dose of said helium at least 20% larger than a remainder of said workpiece. 12. The method of claim 8, wherein said implanting said hydrogen and said implanting said helium are performed sequentially without breaking a vacuum. 13. A method of implanting a workpiece comprising:implanting a uniform dose of hydrogen into said workpiece;implanting a non-uniform dose of helium into said workpiece by altering at least one of a scan speed of said workpiece and an ion beam current of said helium, wherein said helium has a higher dose at a portion of a periphery of said workpiece and wherein said non-uniform dose of said helium is larger than said uniform dose of said hydrogen; andinitiating a split of said workpiece at said portion of said periphery with said higher dose. 14. The method of claim 13, wherein said portion is less than 360° of said periphery of said workpiece. 15. The method of claim 13, wherein said initiating uses at least one of a thermal process or a mechanical process. 16. The method of claim 13, wherein said portion of said periphery has a dose of said helium at least 20% larger than a remainder of said workpiece. 17. The method of claim 13, wherein said implanting said hydrogen and said implanting said helium are performed sequentially without breaking a vacuum.
