Patent number: 7435685Abstract: A method of fabricating an interconnect structure comprising etching a via into an upper low K dielectric layer and into a hardened portion of a lower low K dielectric layer. The via is defined by a pattern formed in a photoresist layer. The photoresist layer is then stripped, and a trench that circumscribes the via as defined by a hard mask is etched into the upper low K dielectric layer and, simultaneously, the via that was etched into the hardened portion of the lower low K dielectric layer is further etched into the lower low K dielectric layer. The result is a low K dielectric dual damascene structure.Type: GrantFiled: September 13, 2006Date of Patent: October 14, 2008Assignee: Applied Materials, Inc.Inventors: Gerardo A.
