Ion Source Thermal Gas Bushing

A system for delivering feed gas to an ion source, comprising:

• a gas tube, having an inner channel in fluid communication with a dopant source;
• an ion source chamber maintained at an elevated temperature;
• and
• a gas bushing, constructed of a thermally isolating material, having an inner channel in fluid communication with the inner channel of the gas tube and the ion source chamber, wherein a temperature of the gas tube is more than 200° C. less than the elevated temperature due to the gas bushing.

A system for delivering feed gas to an ion source, comprising:

• a dopant source;
• a gas tube, having an inner channel in fluid communication with the dopant source;
• an ion source chamber;
• a heat sink in communication with the gas tube;
• and
• a gas bushing, having an inner channel in fluid communication with the inner channel of the gas tube and the ion source chamber so as to deliver feed gas from the dopant source to the ion source chamber, wherein the gas bushing is constructed of a material selected from the group consisting of titanium, quartz, boron nitride, zirconia, and a ceramic material.
