  • Patent number: 11978664
    Abstract: A method includes forming a first conductive feature over a semiconductor substrate, forming an ILD layer over the first conductive feature, patterning the ILD layer to form a trench, and forming a conductive layer over the patterned ILD layer to fill the trench. The method further includes polishing the conductive layer to form a via contact configured to interconnect the first conductive feature with a second conductive feature, where polishing the conductive layer exposes a top surface of the ILD layer, polishing the exposed top surface of the ILD layer, such that a top portion of the via contact protrudes from the exposed top surface of the ILD layer, and forming the second conductive feature over the via contact, such that the top portion of the via contact extends into the second conductive feature.

  • Publication number: 20240146091
    Abstract: A vehicle power management system and a power management method thereof are provided. The power management method includes: determining, by a microcontroller, whether or not a voltage of an ignition-off signal is less than a voltage threshold when the microcontroller receives the ignition-off signal; stopping a vehicle power supply from charging a backup battery, and using the vehicle power supply to charge a back-end load; activating a counter of the microcontroller; stopping the vehicle power supply from charging the back-end load, and using the backup battery to charge the back-end load when a counting time of the counter reaches a first time threshold; sending, by the microcontroller, the ignition-off signal to the back-end load when the counting time of the counter reaches a second time threshold; and stopping the backup battery from charging the back-end load when the counting time of the counter reaches a third time threshold.

  • Publication number: 20240079230
    Abstract: A plasma-assisted annealing system includes a high temperature furnace, a plasma-induced dissociator and a connecting duct. The plasma-induced dissociator is provided to dissociate a working gas and exhaust the dissociated working gas from its working gas outlet. Both ends of the connecting duct are connected to the working gas outlet of the plasma-induced dissociator and a gas inlet of the high temperature furnace, respectively. The working gas dissociated in the plasma-induced dissociator is introduced into the high temperature furnace via the connecting duct.

  • Publication number: 20240066313
    Abstract: An electronic device includes a light emitting layer, a light conversion layer and an adjustable structure. The light emitting layer has a plurality of light emitting units for emitting light. The light conversion layer converts the wavelength of the light emitted by at least one light emitting unit to provide converted light. The adjustable structure is controlled to adjust a light penetrating area to correspond to the affected part to be treated, wherein at least one of the light and the converted light passes through the light penetrating area to irradiate the affected part.

  • Publication number: 20140181857
    Abstract: In a method of controlling a smart television (TV), one or more portable electronic device are authenticated to control the smart TV. When more than one authenticated portable electronic devices send a power-on signal to the smart TV, a normal mode is executed. When only one authenticated portable electronic device sends a power-on signal to the smart TV, a personal mode can be executed. The personal mode comprises a favorite program list, which records names of one or more programs, and a favorite channel list, which records one or more channels and times of broadcasting programs of the channels. Then, the smart TV is controlled according to commands sent by the one or more authenticated portable electronic devices.

  • Publication number: 20140082548
    Abstract: In a method for switching desktops of an electronic device, a plurality of desktop application groups and desktops are preset to corresponding preset position ranges. A current position of the electronic device is determined according to acquired position information from a global position system. When the electronic device is located in one of the preset position ranges, the method determines a position range that the current position is in, and determines a desktop application group and a desktop correspondingly. When the determined desktop is different from a current desktop of the electronic device, the method switches the current desktop to the determined desktop, and displays icons of the determined desktop application group on the determined desktop of the electronic device.
