Patent number: 12243775Abstract: In one embodiment, a method of forming metal interconnects uses a direct metal etch approach to form and fill the metal gap. The method may include directly etching a metal layer to form metal patterns. The metal patterns may be spaced apart from one another by recesses. A dielectric spacer may be formed extending along the sidewalls of each of the recesses. The recesses may be filled with a conductive material to form a second set of metal patterns. By directly etching the metal film, the technique allows for reduced line width roughness. The disclosed structure may have the advantages of increased reliability, better RC performance and reduced parasitic capacitance.Type: GrantFiled: January 27, 2023Date of Patent: March 4, 2025Assignee: Taiwan Semiconductor Manufacturing Company, Ltd.Inventors: Hsi-Wen Tien, Wei-Hao Liao, Yu-Teng Dai, Hsin-Chieh Yao, Chih-Wei Lu, Chung-Ju Lee

Publication number: 20080064767Abstract: The present invention relates to a high-concentration nanoscale silver colloidal solution and the preparing process thereof. The colloidal solution of the present invention comprises a high content of silver particles, i.e. approximately 1.5 wt %. The mean size of the nanoscale silver is less than 10 nm. In the preparing process, silver salt, ionic chelating agent, stabilizing agent, reducing agent, solvent and reaction accelerator are homogeneously mixed together. The increase of reaction temperature by external heat source accelerates completed reaction. By using the specified reaction accelerator and chelating agent and under the operating condition of the present invention, high-density silver colloidal solution is obtained while inhibiting particle aggregation. Therefore, the resulting nanoscale silver colloidal solution contains very small-sized particles and the stability thereof is satisfactory.Type: ApplicationFiled: September 11, 2006Publication date: March 13, 2008Inventors: Kan-Sen Chou, Yu-chieh Lu
