Publication number: 20190391602Abstract: An electronic device manufacturing system includes a mass flow controller (MFC) that has a thermal flow sensor. The thermal flow sensor may measure a mass flow rate and may include a sensor tube having an inner surface coated with a material to form an inner barrier layer. The inner barrier layer may prevent or substantially reduce the likelihood of a corrosive reaction from occurring on the inner surface, which may prevent or reduce the likelihood of the MFC drifting beyond the MFC's mass flow rate accuracy specifications. This may improve the repeatability of flow detection by the MFC. Methods of measuring and controlling a mass flow rate in an electronic device manufacturing system are also provided, as are other aspects.Type: ApplicationFiled: September 6, 2019Publication date: December 26, 2019Inventors: Ming Xu, Sushant S.

Patent number: 10440777Abstract: Implementations described herein provide a method for processing a substrate on a substrate support assembly which enables both lateral and azimuthal tuning of the heat transfer between an electrostatic chuck and a substrate. The method includes processing a first substrate using a first temperature profile on the ESC having primary heaters and spatially tunable heaters. A deviation profile is determined from a result of processing the first substrate from a target result profile. The first temperature profile is adjusted to a second temperature profile on the ESC based on the deviation profile. Adjusting to the second temperature profile includes incrementing the power to one or more spatially tunable heaters in one or more discrete locations corresponding to the deviations profile. A second substrate is then processed on the ESC using the second temperature profile.Type: GrantFiled: January 18, 2016Date of Patent: October 8, 2019Assignee: APPLIED MATERIALS, INC.Inventors: Chunlei Zhang, Phillip Criminale, Steven E.

Patent number: 10410900Abstract: Precision screen printing is described that is capable of sub-micron uniformity of the metallization materials that are printed on green sheet ceramic. In some examples, puck is formed with electrical traces by screen printing a paste that contains metal on a ceramic green sheet in a pattern of electrical traces and processing the printed green sheet to form a puck of a workpiece carrier. In some example, the printing includes applying a squeegee of a screen printer to the printed green sheet in a squeegeeing direction while the green sheet is on a printer bed of the screen printer. The method further includes mapping the printer bed at multiple locations along the squeegeeing direction, identifying non-uniformities in the printer bed mapping, and modifying a printer controller of the screen printer to compensate for mapped non-uniformities in the printer bed.Type: GrantFiled: August 2, 2017Date of Patent: September 10, 2019Assignee: Applied Materials, Inc.Inventors: Shih-Ying Huang, Steven E.
