Patent number: 7193325Abstract: A method of forming a SiCOH etch stop layer in a copper damascene process is described. A substrate with an exposed metal layer is treated with H2 or NH3 plasma to remove metal oxides. Trimethylsilane is flowed into a chamber with no RF power at about 350° C. to form at least a monolayer on the exposed metal layer. The SiCOH layer is formed by a PECVD process including trimethylsilane and CO2 source gases. Optionally, a composite SiCOH layer comprised of a low compressive stress layer on a high compressive stress layer is formed on the substrate. A conventional damascene sequence is then used to form a second metal layer on the exposed metal layer. Via Rc stability is improved and a lower leakage current is achieved with the trimethylsilane passivation layer. A composite SiCOH etch stop layer provides improved stress migration resistance compared to a single low stress SiCOH layer.Type: GrantFiled: April 30, 2004Date of Patent: March 20, 2007Assignee: Taiwan Semiconductor Manufacturing Company, Ltd.Inventors: Zhen-Cheng Wu, Bi-Troug Chen, Weng Chang, Syun-Ming Jang, Su-Horng Lin
