  • Patent number: 12039232
    Abstract: A hardware-in-the-loop (HIL) simulation device is provided, which includes a processing circuit and a pulse-width modulation (PWM) signal observation circuit. The PWM signal observation circuit includes an energy storage unit and the energy storage unit is coupled to the processing circuit. A signal source transmits a PWM signal to the processing circuit and the PWM signal observation circuit, and the energy storage unit is charged when the PWM signal is at high level. The processing circuit detects the voltage of the energy storage unit when detecting the falling edge of the PWM signal so as to calculate the duty cycle of the PWM signal.

  • Publication number: 20220319909
    Abstract: The present disclosure provides a method for manufacturing a semiconductor memory device. Because the present method includes applying a dopant-implanted layer on a semiconductor memory substrate before growing a silicon nitride layer on the substrate, the silicon nitride layer can be grown at an increased rate. The present disclosure avoids a problem encountered in the prior art wherein a seam having a greater length contacts an edge of a contact plug of a semiconductor memory device. Hence, a leakage problem at subsequent operations of semiconductor manufacture can be avoided, and the product yield can be significantly improved.

  • Patent number: 11173561
    Abstract: The present application discloses a method for processing probe. Firstly, a clamping member of a rotation shaft is clamped with a workpiece, and then the workpiece is moved to a processed area by the rotation shaft. The workpiece is rotated by the rotation shaft, and an electrochemical process of the workpiece is performed under the rotation of the shaft and an electrolyte sprayed between the workpiece and the polished module. During the performing of the electrochemical process, it can be that the rotation shaft is moved a processing distance or the included angle of the polish module is changed, for a probe being accomplished from the workpiece. Thereby, the abrasion of the polish module is lower and the performance for processing the probe under the electrochemical process.
