  • Patent number: 11103833
    Abstract: Described is a polyethylene membrane and in particular an ultra-high molecular weight polyethylene member that provides a high air permeability and is hydrophobic. The membranes have small pores and are suitable for sterilization by exposure to gamma radiation. The membranes can be made by methods that involve one or more of stretching the membrane and grafting hydrophobic monomers onto the membrane surface. A perfluorinated monomer, such as perfluoro-n-octyl acrylate, can be grafted to one or more surfaces of the membrane. The membrane have a high flow rate compared to unstretched or ungrafted membranes.

  • Patent number: 11104993
    Abstract: The invention is directed to a configurable vaporizer or ampoule assembly that uses a configurable vessel body, assembled from one or more support tray modules with their own individual heating assemblies or heater members, bounded by a base member and a lid member to form the whole ampoule. This eliminates the need for the prior art ampoule body that normally holds the support trays and was used to heat each of the support trays from the exterior surface using heating jackets or the like.

  • Patent number: 11035038
    Abstract: A solid delivery precursor is described, which is useful for volatilization to generate precursor vapor for a vapor deposition process. The solid delivery precursor comprises solid bodies of compacted particulate precursor, e.g., in a form such as pellets, platelets, tablets, beads, discs, or monoliths. When utilized in a vapor deposition process such as chemical vapor deposition, pulsed chemical vapor deposition, or atomic layer deposition, the solid delivery precursor in the form of solid bodies of compacted particulate precursor provide substantially increased flux of precursor vapor when subjected to volatilization conditions, in relation to the particulate precursor. As a result, vapor deposition process operation can be carried out in shorter periods of time, thereby achieving increased manufacturing rates of products such as semiconductor products, flat-panel displays, solar panels, LEDs, optical coatings, and the like.

  • Patent number: 11020704
    Abstract: System and method for removing molecular contaminants from an air stream are disclosed. The system includes first, second and third filter. The first filter removes organic contaminants from an air stream passing through the first filter. The second filter is downstream of the first filter, is physically and chemically exchangeable with the first filter and removes organic contaminants from the air stream output of the first filter. The third filter, downstream of the second filter, is not exchangeable with the first filter or the second filter. The first position filter can be replaced by the second filter in the second position when the first filter in the first position becomes depleted as detected. A new filter in the second filter position is inserted. Replacing the depleted first filter with the second downstream filter reduces costs and waste while inserting the new filter in the second position ensures removing organic contaminants.
