ABSTRACT:
A porous dielectric element is produced by forming a first dielectric and a second dielectric. The second dielectric is dispersed in the first dielectric. The second dielectric is then removed from the second dielectric by using a chemical dissolution. The removal of the second dielectric from the first dielectric leaves pores in the first dielectric. The pores, which are filled with air, improve the overall dielectric constant of the resulting dielectric element.
