Abstract

One or more substrates may be coiled into one or more coils in such a way that adjacent turns of the coils do not touch one another. The one or more coiled substrates are placed in a treatment chamber where substantially an entire surface of the one or more coiled substrates may be treated with a surface treatment process. One or more spacers may be placed between adjacent layers of the coiled substrate before a full turn of the substrate has been coiled around a carousel.

Claims (34)

1 . A method for treating a substrate surface, comprising the steps of:

coiling one or more substrates into one or more coils in such a way that adjacent turns of the coils do not touch one another;

placing the one or more coiled substrates in a treatment chamber; and

in the treatment chamber, treating substantially an entire surface of the one or more coiled substrates with a surface treatment process.

2 - 5 . (canceled)

6 . The method of claim 1 wherein the surface treatment process includes anodization.

7 . The method of claim 1 wherein the surface treatment process includes drying.

8 . The method of claim 1 wherein the surface treatment process includes annealing.

9 . The method of claim 1 wherein the surface treatment process includes exposure to reactive gas or vapor.

10 . The method of claim 9 wherein the exposure to reactive gas or vapor includes selenization.

11 . The method of claim 1 where the surface treatment includes anodization.

12 . The method of claim 1 where the surface treatment includes electrodeposition.

13 . The method of claim 1 where the surface treatment includes electropolishing.

14 - 23 . (canceled)

24 . A substrate surface treatment system, comprising:

a surface treatment chamber;

a carousel adapted to receive a flexible substrate material as a coil, the carousel being sized to be received within the chamber with the substrate material coiled around the carousel in one or more turns;

a winding mechanism configured to coil the substrate material about the carousel to form a coiled substrate; and

one or more spacers, the spacers being configured to space apart adjacent turns of the coiled substrate in such a way that the adjacent turns of the coiled substrate do not touch one another; and

a mechanism adapted to place one or more of the spacers between adjacent layers of the coiled substrate before the winding mechanism winds a full turn of the substrate material about the carousel.

25 . The system of claim 22 , further comprising one or more sources of reactant gas coupled to the chamber, the reactant gas being of a type suitable for performing atomic layer deposition.

26 . The system of claim 22 , wherein the chamber is an anodization chamber.

27 . The system of claim 22 , wherein the carousel is in the shape of a polygonal cylinder.

28 . The system of claim 25 wherein the carousel is in the shape of a hexagonal cylinder.

29 . The system of claim 22 wherein the spacers can be secured in place with respect to the carousel.

30 . The system of claim 22 wherein the spacers can stack on top of one another.

31 . The system of claim 22 , wherein the spacers include one or more spacer tapes.

32 . The system of claim 29 wherein the spacer tapes run substantially parallel to a length of the substrate.

33 . The system of claim 29 wherein at least one spacer tapes is located proximate a side of the substrate.

34 . An apparatus for treating a substrate surface, comprising:

means for coiling one or more substrates into one or more coils in such a way that adjacent turns of the coils do not touch one another;

treatment chamber means; and

means for treating in the treatment chamber substantially an entire surface of the one or more coiled substrates with a surface treatment process,

wherein the surface treatment process includes one or more atomic layer deposition (ALD) reactions.
