Publication number: 20250239762Abstract: An ammonium fluoride gas may be used to form a protection layer for one or more interlayer dielectric layers, one or more insulating caps, and/or one or more source/drain regions of a semiconductor device during a pre-clean etch process. The protection layer can be formed through an oversupply of nitrogen trifluoride during the pre-clean etch process. The oversupply of nitrogen trifluoride causes an increased formation of ammonium fluoride, which coats the interlayer dielectric layer(s), the insulating cap(s), and/or the source/drain region(s) with a thick protection layer. The protection layer protects the interlayer dielectric layer(s), the insulating cap(s), and/or the source/drain region(s) during the pre-clean process from being etched by fluorine ions formed during the pre-clean process.Type: ApplicationFiled: April 11, 2025Publication date: July 24, 2025Inventors: Li-Wei CHU, Ying-Chi SU, Yu-Kai CHEN, Wei-Yip LOH, Hung-Hsu CHEN, Chih-Wei CHANG, Ming-Hsing TSAI

Publication number: 20250125610Abstract: The embodiment of the present invention relates to a latch current limiter (LCL) circuit for spacecraft and a spacecraft power system using the same. The LCL circuit are coupled between a power supply terminal and a power receiving terminal, wherein a semiconductor switch circuit is configured between the power supply terminal and the power receiving terminal. The semiconductor switch circuit includes a conduction mode, a cut-off mode and a resistance mode. Moreover, an LLC DC-to-DC converter is adopted for controlling the semiconductor switch circuit. When the current is greater than the over-current value, the LLC DC-to-DC converter changes its operational frequency to change the output voltage such that the semiconductor switch circuit is controlled to enter the resistance mode. After a preset period, when the current does not return the regular value, the LLC DC-to-DC converter controls the semiconductor switch circuit to enter the cut-off mode such that the power which supplies to the load is turned off.Type: ApplicationFiled: October 7, 2024Publication date: April 17, 2025Inventors: YU-KAI CHEN, CHUNG-EN HSIAO, YU-SHAN TAI

Patent number: 12126265Abstract: A switch mode power supply circuit with high voltage output, an electrostatic spray apparatus and agricultural plant protection apparatus using the same are provided. The switch mode power supply circuit is electrically connected in series with at least a pre-stage power converter and a post-stage power converter. In order to simplify the control, the switch of the pre-stage power converter is omitted, only one switch of the post-stage power converter is adopted to perform synchronous control. Since the multiple sets of power conversion circuits in the previous stage are connected in series, the turn ratio of the transformer in the power converter in the subsequent stage can be reduced. Therefore, the transformer can be miniaturized and the power supply circuit would be more suitable for agricultural plant protection machine and electrostatic spray apparatus.Type: GrantFiled: October 4, 2022Date of Patent: October 22, 2024Assignee: NATIONAL FORMOSA UNIVERSITYInventors: Yu-Kai Chen, Chau-Chung Song, Hung-Yu Chen
