Abstract
A tubular filament assembly for a CVD silicon deposition reactor is disclosed that provides consistent, low resistance connections to vertical tubular filaments by forming slidable connections between upper and/or lower ends of the tubular filaments and shaped elements cooperative with the bridge and/or the support chucks, so that the connections are insensitive at least to small variations in tilt angle of the vertical filaments and/or the horizontal bridge. The shaped elements can be incorporated into or separate and cooperative with the bridge and/or the chucks. Various embodiments are described.
