Patent number: 12722325Abstract: The present invention relates to a feedstock composition comprising inorganic particles having a multi-modal particle size distribution and comprising a collection of irregular fine particles having a fine particle size distribution and an average fine particle diameter, and a collection of irregular coarse particles having a coarse particle size distribution and an average coarse particle diameter that is in a range from 4 to 7 times the average fine particle diameter. The feedstock composition further comprising a binder composition that is adapted to solidify to form a body comprising the inorganic particles and solidified binder composition. Additionally, the present composition provides a method of forming a shaped body that comprises inorganic particles dispersed in binder composition as well as a method of forming a low porosity inorganic sintered body.Type: GrantFiled: October 23, 2023Date of Patent: September 1, 2026Assignee: Entegris, Inc.Inventors: Thines Kumar Perumal, Subhash Guddati, Christopher James Yannetta, Montray Leavy, Troy Scoggins, Aravind Vasanthakumar

Patent number: 12615988Abstract: A cleaning brush for a semiconductor fabrication process is provided. The cleaning brush includes a core and a brush member. The core includes a circumferential portion and a closed end portion. The circumferential portion surrounds a rotation axis of the cleaning brush and defines an inlet opening for receiving a fluid. The closed end portion is connected to an end of the circumferential portion that is opposite to the inlet opening along the rotation axis. At least one elongated conduit is defined within the core and fluidly communicated with the inlet opening, and the circumferential portion includes a plurality of outlet channels passing therethrough to fluidly communicate with the elongated conduit, the outlet channels being tilted outwardly toward the closed end portion. The brush member is connected to an outer surface of the circumferential portion and covers all of the outlet channels.Type: GrantFiled: May 31, 2023Date of Patent: April 28, 2026Assignee: ENTEGRIS, INC.Inventors: Aravind Vasanthakumar, Thines Kumar Perumal, Subhash Guddati, Montray Leavy

Publication number: 20260016234Abstract: A heat exchanger includes an enclosure with distinct inlets and outlets for hot and cold fluids. The enclosure also houses a heat exchanger core, which includes a partition defining sets of hot and cold fluid channels. This partition features a common boundary between a cold fluid channel and a hot fluid channel facilitating heat exchange between the hot and cold fluids. The partition is designed such that at least some cold fluid channels exhibit variations in the common boundary's area per unit length along their extensions. These changes are designed to promote a predetermined and optimized heat exchange between the cold and hot fluids, increasing heat exchanger's efficiency and offering enhanced thermal performance in a compact and well-structured configuration.Type: ApplicationFiled: July 11, 2025Publication date: January 15, 2026Inventors: Aravind Vasanthakumar, Subhash Guddati, Egnatius Xue Yu Yeo, Chengcheng Wang, Elsufyan Lukman, Montray Leavy, Bruce Hilton, Mitchell Jackson
