Patent number: 7915166Abstract: Films having high hermeticity and a low dielectric constant can be used as copper diffusion barrier films, etch stop films, CMP stop films and other hardmasks during IC fabrication. Hermetic films can protect the underlying layers, such as layers of metal and dielectric, from exposure to atmospheric moisture and oxygen, thereby preventing undesirable oxidation of metal surfaces and absorption of moisture by a dielectric. Specifically, a bi-layer film having a hermetic bottom layer composed of hydrogen doped carbon and a low dielectric constant (low-k) top layer composed of low-k silicon carbide (e.g., high carbon content hydrogen doped silicon carbide) can be employed. Such bi-layer film can be deposited by PECVD methods on a partially fabricated semiconductor substrate having exposed layers of dielectric and metal.Type: GrantFiled: February 22, 2007Date of Patent: March 29, 2011Assignee: Novellus Systems, Inc.Inventors: Yongsik Yu, Pramod Subramonium, Zhiyuan Fang, Jon Henri, Elizabeth Apen, Dan Vitkavage
