Abstract: A hybrid power conversion circuit includes a high-side switch, a low-side switch, a transformer, a resonance tank, a first switch, a second switch, a first synchronous rectification switch, a second synchronous rectification switch, and a third switch. The resonance tank has an external inductor, an external capacitance, and an internal inductor. The first switch is connected to the external inductor. The second switch and a first capacitance form a series-connected path, and is connected to the external capacitance. The first and second synchronous rectification switches are respectively coupled to a first winding and a second winding. The third switch is connected to the second synchronous rectification switch. When an output voltage is less than a voltage interval, the hybrid power conversion circuit operates in a hybrid flyback conversion mode, and otherwise the hybrid power conversion circuit operates in a resonance conversion mode.

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.
