  • Publication number: 20240152193
    Abstract: The invention provides a power supply including at least one power output port, at least one status alert component, and at least one output port status monitoring module. The status alert component generates at least one visual prompt based on an alert signal. The output port status monitoring module includes at least one temperature sensor adjacent to the power output port, a microcontroller connected to the temperature sensor and sensing an output current from the power output port, and a reset signal generator connected to the microcontroller. The microcontroller comprises at least one port status alert condition that takes a temperature and the output current of the power output port as decision factors. The microcontroller outputs the alert signal to the status alert component when the port status alert condition is met and maintains the status until a reset signal provided by the reset signal generator is received.

  • Publication number: 20040253837
    Abstract: A method for forming a dielectric layer of a semiconductor is described. At first, providing a substrate with a metal-conductive layer having been formed thereon. Next covering the substrate with a membrane having a plurality of micro-holes. Afterward spraying a fluid dielectric on the membrane having a plurality of micro-holes. After waiting a period of time for the gaps among the metal conductors being filled with the fluid dielectric, removing the membrane having a plurality of micro-holes from the substrate. Further baking the substrate to cure the fluid dielectric inside metal-conductive layer. The thickness of the dielectric after curing is approximately equal to the thickness of the metal-conductive layer. At last forming a cap dielectric layer on the substrate.
