Abstract: A method includes performing at least two of the following three treatments to produce at least two types of treated water: reverse osmosis, alkalinization, and carbon filtration. The types of treated water are individually dispensed at different times from a common spout. A method includes individually cooling the types of treated water at different times in a common cold tank prior to dispensing. The common cold tank is purged prior to cooling a different type of treated water. A method includes treating water by electrolysis to produce alkaline water and acidic water and producing at least one additional type of treated water by reverse osmosis or carbon filtration. Consumer containers are rinsed with the acidic water. A system includes: a dispensing unit, a treatment unit remotely located from the dispensing unit, treated water supply lines connecting the treatment unit to the dispensing unit, and a process control unit.

Abstract: A mask for exposing a first layer and a second layer on a process substrate, where the first and second layers are two separate layers of an integrated circuit. The mask includes a mask substrate that is substantially completely transmissive to a first wavelength of light and a second wavelength of light. A layer of a first material is disposed on the mask substrate, where the first material is substantially opaque to the first wavelength of light. The layer of the first material is patterned for the first layer. A layer of a second material is disposed on the mask substrate, where the second material is substantially opaque to the second wavelength of light. The layer of the second material is patterned for the second layer, where the layer of the first material and the layer of the second material are aligned on the mask substrate for proper alignment of the first and second layers on the process substrate.
