The invention claimed is: 1. A collapsible fluid container for handling liquid, the fluid container for connecting to a flow path of a liquid delivery system, the fluid container comprising: an interior volume for storing the liquid, the interior volume defining a main chamber and an auxiliary chamber, the main chamber for dispensing liquid into the flow path and the auxiliary chamber for receiving a substance, the interior volume adapted to permit sealing off of the auxiliary chamber from the main chamber; and a fitment sealed to the fluid container, the fitment defining a port communicating with the interior volume of the fluid container. 2. The collapsible fluid container of claim 1, wherein the substance is headspace gas. 3. The collapsible fluid container of claim 1, wherein the substance is liquid from the flow path. 4. The collapsible fluid container of claim 1, wherein the main chamber and the auxiliary chamber are connected. 5. The collapsible fluid container of claim 4, wherein the auxiliary chamber is positioned relative to the main chamber to trap headspace gas. 6. The collapsible fluid container of claim 5, wherein the main chamber tapers towards the auxiliary chamber. 7. The collapsible fluid container of claim 4, wherein the auxiliary chamber tapers towards the main chamber. 8. The collapsible fluid container of claim 4, wherein a sealable passage connects the main chamber and the auxiliary chamber. 9. The collapsible fluid container of claim 1, wherein the interior volume is defined by a flexible liner. 10. The collapsible fluid container of claim 1, wherein the flexible linear is formed from a material impermeable to gas. 11. The collapsible fluid container of claim 1, wherein an outlet fitment is sealed to the fluid container to define a port that communicates with the main chamber of the interior volume and an inlet fitment is sealed to the fluid container to define a port that communicates with the auxiliary chamber of the interior volume. 12. The collapsible fluid container of claim 1, wherein the fluid container is for handling liquid to be used in processing microstructures. 13. A method for filling a fluid container with liquid to minimize headspace, the method comprising: providing a fluid container for holding the liquid in an interior volume having a main chamber and an auxiliary chamber, the auxiliary chamber connected to the main chamber; filling the interior volume of the fluid container with a quantity of liquid so that the main chamber contains the liquid and the auxiliary chamber contains headspace gas; and sealing off the auxiliary chamber from the main chamber so that the headspace gas is trapped in the auxiliary chamber. 14. The method of claim 13, wherein the interior volume is defined by a flexible liner. 15. The method of claim 14, wherein the flexible liner is impermeable to gas. 16. The method of claim 13, wherein the main chamber tapers towards the auxiliary chamber. 17. A method for collecting a substance from a flow path of a liquid delivery system, the method comprising: providing a fluid container having a dispensing chamber and a collection chamber, the dispensing chamber holding a liquid; connecting the dispensing chamber to an inlet end of the flow path; connecting the collection chamber to an outlet end of the flow path; sealing off the collection chamber from the dispensing chamber; and collecting a substance from the flow path in the collection chamber. 18. The method of claim 17, wherein the fluid container has a passage that connects the dispensing chamber and the collection chamber. 19. The method of claim 18, wherein sealing off the collection chamber from the dispensing chamber comprises sealing the passage between the dispensing chamber and the collection chamber to prevent the substance collected in the collection chamber from entering the dispensing chamber. 20. The method of claim 19, further comprising: unsealing the passage to allow at least some of the substance collected in the collection chamber to enter the dispensing chamber. 21. The method of claim 17, wherein the substance is liquid from the flow path. 22. The method of claim 17 further comprising: supplying the liquid from the dispensing chamber into the flow path of the liquid delivery system. 23. The method of claim 22 wherein sealing off the collection chamber from the dispensing chamber comprises: removing headspace gas from the dispensing chamber of the fluid container before supplying the liquid into the flow path, wherein the headspace gas is removed from the dispensing chamber by sealing a passage between the dispensing chamber and the collection chamber so the headspace gas is trapped in the collection chamber. 24. A method of manufacturing a semiconductor device using the fluid container of claim 1 to dispense a material as part of the semiconductor manufacturing process. 25. The method of claim 24, wherein the material is a photoresist solution.
