  • Patent number: 11978740
    Abstract: A layer stack including a first bonding dielectric material layer, a dielectric metal oxide layer, and a second bonding dielectric material layer is formed over a top surface of a substrate including a substrate semiconductor layer. A conductive material layer is formed by depositing a conductive material over the second bonding dielectric material layer. The substrate semiconductor layer is thinned by removing portions of the substrate semiconductor layer that are distal from the layer stack, whereby a remaining portion of the substrate semiconductor layer includes a top semiconductor layer. A semiconductor device may be formed on the top semiconductor layer.

  • Publication number: 20240136346
    Abstract: A semiconductor die package includes an inductor-capacitor (LC) semiconductor die that is directly bonded with a logic semiconductor die. The LC semiconductor die includes inductors and capacitors that are integrated into a single die. The inductors and capacitors of the LC semiconductor die may be electrically connected with transistors and other logic components on the logic semiconductor die to form a voltage regulator circuit of the semiconductor die package. The integration of passive components (e.g., the inductors and capacitors) of the voltage regulator circuit into a single semiconductor die reduces signal propagation distances in the voltage regulator circuit, which may increase the operating efficiency of the voltage regulator circuit, may reduce the formfactor for the semiconductor die package, may reduce parasitic capacitance and/or may reduce parasitic inductance in the voltage regulator circuit (thereby improving the performance of the voltage regulator circuit), among other examples.

  • Patent number: 11949226
    Abstract: An external power supply system for spindles is revealed. The external power supply system includes a tool holder, a rectifier circuit, an overvoltage protection circuit. and a buck/boost converter. The tool holder receives an external power source of a spindle while the rectifier circuit converts the external power source into a rectified output signal with a power factor through step-down transformation. The overvoltage protection circuit is used to check whether the rectified output signal is larger than an overvoltage signal for outputting an operating potential or a non-operating potential. The buck/boost converter is used for receiving the rectified output signal with the power factor and converting the rectified output signal to an output voltage according to the power factor. Then the output voltage is provided to a load of a low voltage power supply, a high voltage power supply, or a constant voltage power supply.

  • Publication number: 20240105644
    Abstract: A semiconductor die package includes a high dielectric constant (high-k) dielectric layer over a device region of a first semiconductor die that is bonded with a second semiconductor die in a wafer on wafer (WoW) configuration. A through silicon via (TSV) structure may be formed through the device region. The high-k dielectric layer has an intrinsic negative charge polarity that provides a coupling voltage to modify the electric potential in the device region. In particular, the electron carriers in high-k dielectric layer attracts hole charge carriers in device region, which suppresses trap-assist tunnels that result from surface defects formed during etching of the recess for the TSV structure. Accordingly, the high-k dielectric layer described herein reduces the likelihood of (and/or the magnitude of) current leakage in semiconductor devices that are included in the device region of the first semiconductor die.
