Abstract: Some implementations described herein include systems and techniques for fabricating a wafer-on-wafer product using a filled lateral gap between beveled regions of wafers included in a stacked-wafer assembly and along a perimeter region of the stacked-wafer assembly. The systems and techniques include a deposition tool having an electrode with a protrusion that enhances an electromagnetic field along the perimeter region of the stacked-wafer assembly during a deposition operation performed by the deposition tool. Relative to an electromagnetic field generated by a deposition tool not including the electrode with the protrusion, the enhanced electromagnetic field improves the deposition operation so that a supporting fill material may be sufficiently deposited.

Abstract: A radial-flow heat-dissipating fan includes a casing and a cover mounted to a side of the casing. The casing includes a compartment and a side air outlet, and the cover includes an air inlet. A primary fan wheel is rotatably mounted in the compartment and the primary fan wheel includes a hub and a plurality of radial-flow blades surrounding the hub. An auxiliary fan wheel is mounted in the air inlet of the cover and includes a plurality of axial-flow blades. An airflow transition area is defined between a circumference of the hub of the primary fan wheel, the radial-flow blades, and the axial-flow blades. The axial-flow blades increase axial inlet airflow via the air inlet, with the airflow transition area changing a direction of the axial inlet airflow into centrifugal airflow that is outputted via the side air outlet by the radial-flow blades.
