Abstract
Porous dielectric layers are produced by introducing pores in pre-formed composite dielectric layers. The pores may be produced after the barrier material, the metal or other conductive material is deposited to form a metallization layer. In this manner, the conductive material is provided with a relatively smooth continuous surface on which to deposit.
