摘要： A fluid handling device with an anisotropic wetting surface including a substrate with a multiplicity of asymmetric substantially uniformly shaped asperities thereon. Each asperity has a first asperity rise angle and a second asperity rise angle relative to the substrate. The asperities are structured to present a desired retentive force ratio (f1/f2) greater or less than unity caused by asymmetry between the first asperity rise angle and the second asperity rise angle according to the formula: f3/f2=sin(ω3+½Δθ0)/sin(ω2+½Δθ0).

摘要： Embodiments of the invention include articles comprising a diamond like carbon coating or doped diamond like carbon coating on one or more surfaces of a plastic substrate or a plastic enclosure. Embodiments of the DLC or doped DLC coatings reduce the gas permeation of the coated plastic or thermoplastic to hydrogen or helium compared to the permeability of the plastic alone. The DLC or doped DLC coatings coating provides a surface resistivity of from about 107 to about 1014 ohm/square and have a transmittance that range from about 0% to about 70% less than the transmittance of the underlying plastic substrate in the range of about 300 nm to about 1100 nm. The DLC coated plastic can be used in environmental enclosures for protecting environmentally sensitive substrates such as semiconductor wafers and reticles.

摘要： Embodiments of the invention include or comprise super wetting structured surfaces having one or more asperities, sometimes referred to as hemi-wicking. Structured substrates with regular arrays of asperities such as square pillars or frustra were machined from graphite blocks and then treated to render them lyophilic. Liquids spread over these surfaces to produce non-circular wetting areas. As the channels formed between the asperities were made shallower or narrower, liquids wicked more and spread over a larger area. The inherent wettability of the substrate was independent or nearly independent of the substrate. A combination of the appropriate surface structure and moderate inherent wettability can effectively flatten liquids, spreading them over very large areas.

摘要： A tray carrier with ultraphobic surfaces for promoting more effective cleaning and drying of the tray carrier. In the invention, entire surfaces or portions of surfaces of a tray carrier are made ultraphobic. The ultraphobic surfaces of the tray carrier cause liquids that may come in contact with the surface, such as may be used in cleaning, to quickly and easily “roll off” without leaving a liquid film or substantial quantity of liquid droplets. As a result, less time and energy is expended in drying the surfaces, and redeposited residue is minimized, thereby improving overall process quality and facilitating economical reuse of the tray carrier. In addition, the ultraphobic surfaces may be resistant to initial deposition of contaminants, where the contaminants may be in liquid or vapor form.
