Abstract :
The drive for greater integrated circuit performance has led to the need for faster interconnect systems and the development of porous ultra low k dielectrics. The porous structure and lower modulus has made integration a greater challenge. Nanoglass TM E is one such spin-on dielectric that has been optimized for this challenge. In this study, Nanoglass TM E dielectric copper single level Damascene integration has been successfully demonstrated. Direct CMP tests of Nanoglass TM E blanket films have demonstrated damage free polishing with 7 psi downforce.
