Publication number: 20250031433Abstract: A method for fabricating a semiconductor structure is disclosed. A substrate having a dielectric layer thereon and a gate trench formed in the dielectric layer is prepared. The substrate is subjected to a physical vapor deposition (PVD) process in a physical vapor deposition chamber equipped with an auto capacitance tuner to conformally deposit a metal layer on a top surface of the dielectric layer and on an interior surface of the gate trench. The PVD process comprises: (i) tuning the auto capacitance tuner to provide positive radio frequency (RF) bias to the substrate in the PVD chamber for a first time period; and (ii) subsequently tuning the auto capacitance tuner to provide negative RF bias to the substrate in the PVD chamber for a second time period.Type: ApplicationFiled: August 14, 2023Publication date: January 23, 2025Applicant: United Semiconductor (Xiamen) Co., Ltd.Inventors: Shouguo Zhang, Yongbo Xu, Wen Yi Tan

Patent number: 10954602Abstract: A method of electro-chemical plating is disclosed. The catholyte is delivered to the cathode chamber. The catholyte is controlled at a first temperature before flowing into the cathode chamber. The anolyte is provided at room temperature. The temperature of the anolyte is lowered from the room temperature to a second temperature before delivering into the anode chamber. The second temperature is equal to or lower than the first temperature. The plating surface of the substrate is immersed in the electrolyte. The substrate is biased to a direct current (DC) voltage. The biased substrate attracts ions of the metal in the electrolyte toward the plating surface so as to electroplating the metal onto the substrate.Type: GrantFiled: November 13, 2019Date of Patent: March 23, 2021Assignee: United Semiconductor (Xiamen) Co., Ltd.Inventors: Shouguo Zhang, Jinggang Li, Yongbo Xu, Xijun Guo, Pao-Chung Lee

Patent number: 10510549Abstract: A method of fabricating a metal layer includes performing a first re-sputtering to remove a metal compound formed on a conductive layer. The first re-sputtering includes bombarding the metal compound and a dielectric layer on the conductive layer by inert ions and metal atoms. Then, a barrier is formed on the dielectric layer and the conductive layer. Later, a bottom of the barrier is removed. Subsequently, a metal layer is formed to cover the barrier.Type: GrantFiled: December 25, 2017Date of Patent: December 17, 2019Assignee: UNITED MICROELECTRONICS CORP.Inventors: Shouguo Zhang, Hai Tao Liu, Ming Hua Du, Yen-Chen Chen
