An atomic layer deposition (ALD) apparatus is, suitable for thermal ALD and plasma-enhanced ALD of conductive and non-conductive films. The ALD apparatus can maintain electrical insulation of a gas dispersion structure, such as a showerhead assembly, which acts as an RF electrode to generate plasma inside a reaction chamber while depositing electrically conductive films in the reaction chamber. Fine tubules of micro-feeding tube assembly prevents plasma generation in them and reactive gases each have separate flow paths through the micro-feeding tube assembly. Process gases out of the micro-feeding tube assembly enter narrow grooves of a helical flow inducing plate and form helical flows which mix well each other. Symmetrically mounted pads on showerhead assembly and flow guiding plate maintain a symmetrical gap through which an inert gas flows continuously to keep reactive gases outside the gap and unwanted film deposition in the gap. Longer operating time before maintenance (cleaning) and thus higher productivity can be achieved.

A thermal insulation batt is created from recycled carpet fibers and fire resistant cotton shoddy bonded by staples of bi-component fiber having a polyester core and low melting polymeric sheath. The low melting polymeric sheath melts at a temperature well below the melting or degradation temperature of any of the carpet fibers from the recycled carpets. Since the sheath has a small thickness, the amount of melt created is small and bonding occurs only between the bi-component staple fiber and adjacent carpet fiber or fire resistant cotton shoddy without melt overflow. The rigidized thermal insulation batt can be used in a building between studs and may be used in an automobile door for sound proofing. This product is particularly well suited for use as acoustic and thermal insulation in buildings as “non-load bearing” partitions in interior offices of commercial buildings. This bonded low density composite fibrous structure has fire retarding constituents incorporated within the batt to retard propagation of building fire. These stated uses are non-limiting; and other uses are contemplated, including automobile interior structures.
