Publication number: 20250104785Abstract: A memory circuit includes first and second NVM devices and a driver circuit including first and second power switches and first and second drivers. The first and second power switches generate first and second power signals, the first and second drivers output first and second activation signals to the first and second NVM devices responsive to the first and second power signals, respectively, and the driver circuit is configured to output a third activation signal having a voltage less than that of the first activation signal to the first NVM device and to output a fourth activation signal having a voltage less than that of the second activation signal to the second NVM device. The first activation signal and the third activation signal are based on a first enable signal, and the second activation signal and the fourth activation signal are based on a second enable signal.Type: ApplicationFiled: December 9, 2024Publication date: March 27, 2025Inventors: Gu-Huan LI, Chen-Ming HUNG, Yu-Der CHIH

Publication number: 20250107117Abstract: A Schottky diode includes a substrate with an epitaxy layer on which a cathode region and an anode region are defined. A cathode structure and an anode structure are formed in the cathode region and the anode region respectively and horizontally separated by a distance. The anode structure includes a plurality of p-type doped regions diffused from the epitaxy layer toward the substrate, with an interval is formed between adjacent two p-type doped regions. A backside metal film and a backside protection layer are sequentially formed on a back surface of the substrate. Since the manufacturing of the Schottky diode does not involve wire bonding and molding processes, the overall thickness of the Schottky diode is reduced and heat dissipation is improved. With the backside metal film on the back side of the substrate, an equivalent resistance and a forward voltage of the Schottky diode can be reduced.Type: ApplicationFiled: November 15, 2023Publication date: March 27, 2025Inventors: CHUNG-HSIUNG HO, CHI-HSUEH LI, CHIA-WEI CHEN, YU-MING HSU, WEN-LIANG HUANG, MING-KUN HSIN, SHIH-MING CHEN

Publication number: 20250092511Abstract: A vapor deposition system is described. The vapor deposition system includes a reaction chamber and a reactant delivery subsystem coupled with the reaction chamber. The reaction chamber is configured to retain a substrate therein. The reactant delivery subsystem includes inlets, a pre-reaction region, and outlets. The inlets receive precursors and chalcogen precursor(s). The pre-reaction region is configured to receive the precursors from a portion of the inlets and to react at least a portion of the precursors to form modified precursor(s). The modified precursor(s) are more thermally stable than metal-containing precursor(s) of the precursors used to form the modified precursor(s). The outlets are coupled with the reaction chamber and the pre-reaction region. The outlets separately provide the modified precursor(s) and the chalcogen precursor(s) to the reaction chamber. The modified precursor(s) and the chalcogen precursor(s) react and form a chalcogen film on the substrate in the reaction chamber.Type: ApplicationFiled: September 3, 2024Publication date: March 20, 2025Inventors: Lain-Jong Li, Yi Wan, Yu-Ming Chang
