  • Patent number: 11065575
    Abstract: A device for exchange of water molecule and temperature between two fluids. The device comprises thin molecular sieve membrane sheets that allow water molecules to permeate through while blocking cross-over of the exchanging fluids. The device provides two sets of flow channels having a hydraulic diameter ranged from 0.5 to 2.0 mm for respective process and sweep fluid flows. The two sets of the channels are separated by a membrane sheet having a thickness less than 200 ?m. The thin molecule sieve membrane may be prepared by forming an ultra-thin zeolite membrane layer on a porous metal-based support sheet which provides very high water permeance so that the exchange can be conducted in a compact membrane module at high throughput. The device can be used to remove water from a process stream of higher water content by use of a sweep fluid of lower water content or higher water affinity.

  • Patent number: 9876091
    Abstract: After formation of a silicon nitride gate spacer and a silicon nitride liner overlying a disposable gate structure, a dielectric material layer is deposited, which includes a dielectric material that is not prone to material loss during subsequent exposure to wet or dry etch chemicals employed to remove disposable gate materials in the disposable gate structure. The dielectric material can be a spin-on dielectric material or can be a dielectric metal oxide material. The dielectric material layer and the silicon nitride liner are planarized to provide a planarized dielectric surface in which the disposable gate materials are physically exposed. Surfaces of the planarized dielectric layer is not recessed relative to surfaces of the silicon nitride layer during removal of the disposable gate materials and prior to formation of replacement gate structures, thereby preventing formation of metallic stringers.
