Patent number: 8603632Abstract: 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.Type: GrantFiled: March 20, 2013Date of Patent: December 10, 2013Assignee: Entegris, Inc.Inventors: Charles W.

Patent number: 8028722Abstract: 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(?3+½??0)/sin(?2+½??0).Type: GrantFiled: September 15, 2006Date of Patent: October 4, 2011Assignee: Entegris, Inc.Inventors: Charles W.

Publication number: 20100136289Abstract: 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.Type: ApplicationFiled: May 19, 2008Publication date: June 3, 2010Inventors: Charles W.

Patent number: 7128212Abstract: A sealing system, sealing system components, and methods of manufacture and use for a vessel that holds corrosive liquid, with the sealing system having a port on the vessel, an insert, and a sealing element. The sealing element is corrosion-resistant, essentially impermeable to corrosive and critical fluids, essentially free of leachable impurities and is made with a material having a Shore A hardness between about 70 and about 95. A preferred material for the sealing ring is the class of materials known as polyolefins. The insert is operably engageable with the port and the sealing element to create a seal between the sealing element and the first and second sealing surfaces to prevent fluid flow through the port.Type: GrantFiled: January 25, 2002Date of Patent: October 31, 2006Assignee: Entegris, Inc.Inventors: Anthony Gargano, Keith Gossen, Charles W.

Patent number: 6976585Abstract: A carrier with ultraphobic surfaces for promoting more effective cleaning and drying of the carrier. In the invention, entire surfaces or portions of surfaces of a carrier are made ultraphobic. The ultraphobic surfaces of the 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 number 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. In addition, the ultraphobic surfaces may be resistant to initial deposition of contaminants, where the contaminants may be in liquid or vapor form.Type: GrantFiled: June 3, 2003Date of Patent: December 20, 2005Assignee: Entegris, Inc.Inventor: Charles W. Extrand

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.Type: GrantFiled: June 3, 2003Date of Patent: September 6, 2005Assignee: Entegris, Inc.Inventor: Charles W.
