Patent number: 6797343Abstract: New precursors and processes are disclosed for making fluorinated, low dielectric constant ∈ thin films that have higher dimensional stability and are more rigid than fluorinated poly (para-xylylenes). The fluorinated, low dielectric constant thin films can be prepared from reactions of an ethylenic-containing precursor with benzocyclobutane-, biphenyl- and/or dieneone-containing precursors. The fluorinated, low dielectric constant thin films are useful for fabrications of future <0.13 &mgr;m integrated circuits (ICs). Using fluorinated, low-dielectric constant thin films prepared according to this invention, the integrity of the dielectric, copper (Cu) and barrier metals, such as Ta, can be kept intact; therefore improving the reliability of the IC.Type: GrantFiled: December 20, 2001Date of Patent: September 28, 2004Assignee: Dielectric Systems, Inc.Inventor: Chung J.
