  • Publication number: 20240131538
    Abstract: An annular airflow regulating apparatus includes a cup-shaped element and an adjustment element. The cup-shaped element has a bowl and a bottom, integrated to form a first chamber. The bottom has a tapered channel parallel to an axis and penetrating through the bottom. A ring-shaped groove is disposed between the tapered channel and the bottom. The ring-shaped groove has an annular plane perpendicular to the axis. The adjustment element, having a tapered portion and second holes, is movably disposed in the cup-shaped element. The tapered portion protrudes into the tapered channel A tapered annular gap is formed between the tapered portion and the tapered channel. When the adjustment element is moved with respect to the cup-shaped element, a width of the tapered annular gap is varied, and thereupon a flow rate and velocity of the process gas would be varied accordingly.

    Abstract: A method and apparatus for forming tungsten features in semiconductor devices is provided. The method includes exposing a top opening of a feature formed in a substrate to a physical vapor deposition (PVD) process to deposit a tungsten liner layer within the feature. The PVD process is performed in a first processing region of a first processing chamber and the tungsten liner layer forms an overhang portion, which partially obstructs the top opening of the feature. The substrate is transferred from the first processing region of the first processing chamber to a second processing region of a second processing chamber without breaking vacuum. The overhang portion is exposed to nitrogen-containing radicals in the second processing region to inhibit subsequent growth of tungsten along the overhang portion. The feature is exposed to a tungsten-containing precursor gas to form a tungsten fill layer over the tungsten liner layer within the feature.

  • Publication number: 20240079947
    Abstract: This document describes systems and techniques for a current-limiting control strategy for single-loop droop-controlled grid-forming inverters. In aspects, a hysteresis module is configured to compare an output current detected across one or more transistors in an inverter controlled by the single-loop droop converter with a specified maximum current and to generate an overcurrent signal. The overcurrent signal presents a fault signal responsive to the output current exceeding the specified maximum current. A logic array is configured to logically combine gate control signals generated by the single-loop droop controller to selectively direct the one or more transistors to allow the output current to flow therethrough with the overcurrent signal to present modified gate control signals to the one or more transistors.

  • Patent number: 11813695
    Abstract: A method for forming a large-diameter special-shaped cross section thin-wall tubular part. A tailor welded barrel blank is adopted as an original blank for forming of the large-diameter special-shaped cross section thin-wall tubular part. After a desired shape is formed, the original weld joint is removed and butt joint tailor welding is performed on the tubular part again. Since the tailor weld joint of the original barrel blank is removed from the final part, there is no need to consider the consistency or coordination of the microstructure of the weld joint and the base metal during the forming process and the subsequent thermal treatment process.
