Fabrication flash drying

Several variations on the conventional pre-cure process have been explored, including short one-step flash-dry-curing (shock condensation) of cellulosic fabrics with the risk of crosslinker migration during the quick drying. The...

Often after fabrication, metal surfaces are protected by oils or a rust preventative to minimize the reaction of the surface with the environment. For example, an oxide-free tool steel surface will form flash rust immediately on exposure to the atmosphere. To prevent the flash rust a flash rust inhibitor is absorbed on the surface before the cleaned surface is allowed to dry. These additives may act as contaminants in further processing and often are removed by in situ cleaning in the deposition system.

Si02 films with different thicknesses are produced by oxidation (dry or wet) for different applications. Thick oxide films (0.1 to 1 pm), normally grown by wet oxidation, are used for device isolation and as masking layers thin oxide layers (< lOOnm) are finding applications as gate dielectrics, flash memory tunnel oxides and dynamic random access memory (DRAM) capacitor oxides. For reasons of space, only the literature on the fabrication of ultra-thin oxide films and the oxidation behaviour of low-dimensional Si nanostructures will be summarized in this chapter. Detailed discussions on the oxidation mechanisms and modelling of Si oxidation have been the subject of several excellent reviews [20-26].
