Copper coplanar waveguides in Si substrates for 10 GHz applications
Journal of Vacuum Science and Technology A , Volume 22 - Issue 3 p. 847- 850
The fabrication of Copper coplanar waveguides on Silicon substrates was investigated. Plated copper metallization was found to improve the performance of coplanar waveguide transmission lines, fabricated on CMOS-compatible silicon substrate. Copper/polyimide devices increased the phase velocity of the transmission line by a factor of √2. The lower resistance of the copper and improved substrate isolation obtained with the low-k polyimide dielectric was found to enhance the performance of these lines.
