Abstract

A hybrid ion source, comprising a source body configured to create plasma therein, from a first material, wherein the first material comprises one of monatomic gases, small molecule gases, large molecule gases, reactive gases, and solids, a low power plasma generation component operably associated with the source body, a high power plasma generation component operably associated with the source body and an extraction aperture configured to extract ions of the ion plasma from the source body.

Claims (15)

1. A hybrid ion source, comprising:

a source body configured to create ion plasma therein from a first material, wherein the first material comprises one of monatomic gases, small molecule gases, large molecule gases, reactive gases, and solids;

a low power plasma generation component operably associated with the source body;

a high power plasma generation component operably associated with the source body;

an extraction aperture configured to extract ions of the ion plasma from the source body; and

a controller configured to selectively activate the low power plasma generation component and the high power plasma generation component based on a selected mode of operation, wherein when the selected mode of operation is a low power mode, only the low power plasma generation component is activated, wherein when the selected mode of operation is a high power clean mode, only the high power plasma generation component is activated, and wherein when the selected mode of operation is a standard high power mode, both the high power plasma generation component and low power plasma generation component are activated.

2. The hybrid ion source of claim 1 , wherein the low power plasma generation component comprises a cathode heater filament, a repeller plate at a filament potential and an anode.

3. The hybrid ion source of claim 1 , wherein the high power plasma generation component comprises an RF antenna.

4. The hybrid ion source of claim 3 , wherein the RF antenna is water cooled.

5. The hybrid ion source of claim 3 , wherein the RF antenna is at least partially surrounded by an insulative tube.

6. The hybrid ion source of claim 1 , wherein the monatomic gases comprise one of the following: boron (B), cobalt (Co), argon (Ar), titanium (Ti), oxygen (O) and phosphorus (P).

7. The hybrid ion source of claim 1 , wherein the small molecule gases comprise one of the following: germanium tetrafluoride (GeF 4 ), silicon tetrafluoride (SiF 4 ), boron trifluoride (BF 3 ), phosphorous trifluoride (PF 3 ), Phosphine (PH 3 ), and Arsine (AsH 3 ).

8. The hybrid ion source of claim 1 , wherein the reactive gases comprise one of the following: oxygen (O 2 ), fluorine (F 2 ), and NF 3 .

9. The hybrid ion source of claim 1 , wherein the large molecule gases comprise one of the following: decaborane (B 10 H 14 ), octadecaborane (B 18 H 22 ).

10. The hybrid ion source of claim 1 , further comprising an extraction apparatus associated with the extraction aperture, wherein the extraction apparatus is operable to extract ions from the source body through the extraction aperture to generally form an ion beam associated with the beam path region.
