SILICON GAS INJECTOR AND METHOD OF MAKING

摘要

A gas injector tube (40) usable in a batch thermal treatment oven including two silicon shells (54, 56) joined together with an adhesive formed of a fine silicon powder and a curable silica-forming agent, such as a spin-on glass, which is ultrasonically homogenized. The tube may have a gas outlet (52) on its distal end or be sealed with a silicon cap (86) and have side outlet holes (84) formed along its side. The silicon injector tube may be used in combination with a silicon tower and a silicon liner so that all bulk parts within the furnace hot zone are formed of silicon.
