Etching aluminum nitride or aluminum oxide to generate an aluminum ion beam

An ion implantation system, comprising:

• a ceramic member comprising an aluminum-based source material;
• an ion source configured to ionize the aluminum-based source material and form an ion beam therefrom, and whereby the ionization of the aluminum-based source material further forms a by-product comprising a non-conducting material, wherein the ceramic member comprises a shield within the ion source, wherein the shield does not comprise an electrode;
• an etchant gas supply containing no dopant material and comprising a pressurized bottle containing an etchant gas mixture of fluorine gas mixed with a noble gas, wherein the etchant gas supply is configured to introduce the etchant gas mixture to the ion source, wherein the fluorine gas is mixed with the noble gas at a health safety concentration;
• a beamline assembly configured to selectively transport the ion beam;
• and
• an end station configured to accept the ion beam for implantation of ions into a workpiece.

An ion implantation system, comprising:

• an ion source comprising a ceramic member comprising an aluminum-based ceramic dopant material, wherein the ceramic member comprises a shield within the ion source and does not comprise an electrode, and wherein the ion source is configured to ionize the aluminum-based ceramic dopant material and form an ion beam therefrom, and whereby the ionization of the aluminum-based ceramic dopant material further forms a by-product comprising an insulating material;
• a pressurized gas bottle in fluid communication with the ion source, wherein the pressurized gas bottle contains no dopant material and comprises an etchant gas mixture comprising a non-reacted mixture of less than approximately 20% fluorine and approximately 75% to 80% helium;
• a beamline assembly configured to selectively transport the ion beam;
• and
• an end station configured to accept the ion beam for implantation of ions into a workpiece.
