Publication number: 20240278991Abstract: Systems for tracking consumable parts in a substrate processing system includes a mounting enclosure with a consumable parts station used for storing consumable parts within. The mounting enclosure has an opening toward an EFEM to enable a robot of the EFEM to retrieve a consumable part from the consumable parts station. An image capture system is configured to capture an image of a code on the consumable part. The image capture system includes a camera and a light source. The image capture system is positioned near the opening of the mounting enclosure, such that the camera and the light source are pointed toward the opening. A processor is communicatively connected to the image capture system and to a controller. The controller causes the robot to move the consumable part from the consumable parts station via the opening and to position the code on the consumable part within a field of view of the image capture system.Type: ApplicationFiled: June 15, 2022Publication date: August 22, 2024Inventors: Hossein Sadeghi, Damon Tyrone Genetti, Deqi Wang, Scott Baldwin

Patent number: 11901227Abstract: Described herein are methods of filling features with tungsten, and related systems and apparatus, involving inhibition of tungsten nucleation. In some embodiments, the methods involve selective inhibition along a feature profile. Methods of selectively inhibiting tungsten nucleation can include exposing the feature to a direct or remote plasma. Pre-inhibition and post-inhibition treatments are used to modulate the inhibition effect, facilitating feature fill using inhibition across a wide process window. The methods described herein can be used to fill vertical features, such as in tungsten vias, and horizontal features, such as vertical NAND (VNAND) wordlines. The methods may be used for both conformal fill and bottom-up/inside-out fill. Examples of applications include logic and memory contact fill, DRAM buried wordline fill, vertically integrated memory gate and wordline fill, and 3-D integration using through-silicon vias.Type: GrantFiled: October 8, 2021Date of Patent: February 13, 2024Assignee: Lam Research CorporationInventors: Anand Chandrashekar, Esther Jeng, Raashina Humayun, Michal Danek, Juwen Gao, Deqi Wang
