Patent ID: 8052795

Claim:
A catalyst-enhanced chemical vapor deposition apparatus, comprising: a vacuum process chamber; a showerhead disposed in the process chamber to introduce process gas into a vacuum within the process chamber; a tensile catalyst wire structure disposed in the process chamber, with the tensile catalyst wire structure comprising: a frame; a first plurality of tensioners formed on a first side of the frame; a second plurality of tensioners formed on a second and opposite side of the frame; a catalyst wire strung between the first and second pluralities of tensioners, with each one of the first and second pluralities of tensioners comprising a piston linearly aligned at a turn of the catalyst wire extending between the opposite sides of the frame to reciprocate with different corresponding lengths of the catalyst wire and applying tension to the catalyst wire while the catalyst wire is decomposing the process gas introduced from the showerhead, the piston comprising a piston shaft and a gas supply line disposed throughout the piston and the piston shaft and extending in parallel with an axial extending direction of the piston and the piston shaft; and a substrate on which the gas decomposed by the catalyst wire structure is deposited.
