Since the amorphous carbon film is formed by controlling an additive amount of Si (silicon) during film formation, it is possible to form the amorphous carbon film having a high elastic modulus and a low thermal contraction rate with a suppressed dielectric constant as low as 3.3 or less. Accordingly, when the amorphous carbon film is used as a film in the semiconductor device, troubles such as a film peeling can be suppressed.Type: ApplicationFiled: November 30, 2007Publication date: February 11, 2010Applicant: TOKYO ELECTRON LIMITEDInventors: Yoshiyuki Kikuchi, Yasuo Kobayashi, Kohei Kawamura, Toshihisa Nozawa, Hiraku Ishikawa

Publication number: 20090302474Abstract: The present invention relates to a very thin multilayer diffusion barrier for a semiconductor device and fabrication method thereof. The multilayer diffusion barrier according to the present invention is fabricated by forming a very thin, multilayer diffusion barrier composed of even thinner sub-layers, where the sub-layers are only a few atoms thick. The present invention provides a diffusion barrier layer for a semiconductor device which is in a substantially amorphous state and thermodynamically stable, even at high temperatures.Type: ApplicationFiled: August 13, 2009Publication date: December 10, 2009Inventors: Katayun Barmak, Hyungjun Kim, Ismail C. Noyan, Stephen M. Rossnagel

Publication number: 20090206485Abstract: An interconnect structure including a gouging feature at the bottom of one of the via openings and a method of forming the same are provided. In accordance with the present invention, the method of forming the interconnect structure does not disrupt the coverage of the deposited diffusion barrier in the overlying line opening, nor does it introduce damages caused by Ar sputtering into the dielectric material including the via and line openings. In accordance with the present invention, such an interconnect structure contains a diffusion barrier layer only within the via opening, but not in the overlying line opening. This feature enhances both mechanical strength and diffusion property around the via opening areas without decreasing volume fraction of conductor inside the line openings.Type: ApplicationFiled: April 27, 2009Publication date: August 20, 2009Applicant: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: Chih-Chao Yang, Terry A.
