Sponges, Skyscrapers, And Low-K

A sponge is a porous structure. So is a skyscraper. These two very different images exemplify the materials being considered for advanced low dielectric constant (κ) materials. Most porous dielectrics that have been tested up to this point resemble sponges. As Intel’s David Michalak explained at this month's Materials Research Society (MRS) Spring Meeting, these materials consist of a ba... » read more
