Abstract:
A reaction system and method for preparing compounds or intermediates from solid reactant materials is provided. In a specific aspect, a reaction system and methods are provided for preparation of boron-containing precursor compounds useful as precursors for ion implantation of boron in substrates. In another specific aspect, a reactor system and methods are provided for manufacture of boron precursors such as B 2 F 4 .

Claim (Index 32):
A method of forming B 2 F 4  comprising:\n reacting BF 3  gas and boron-containing solids to form a first gaseous mixture comprising BF and unreacted BF 3  gas; cooling the first gaseous mixture under temperature and pressure conditions effective to condense the first gaseous mixture to form a first condensed product; volatilizing the first condensed product to form a second gaseous mixture comprising B 2 F 4  and BF 3 ; cooling the second gaseous mixture under temperature and pressure conditions effective to condense the second gaseous mixture to form a second condensed product and a third gaseous mixture comprising B 2 F 4  and BF 3 ; filtering the third gaseous mixture to remove particulates; and recovering B 2 F 4  from the third gaseous mixture.
