A synthetic, three-dimensional macromolecule formed using a nanoscale fabrication process. A dendrimer is built up from a monomer, with new branches added in steps until a tree-like structure is created (dendrimer comes from the Greek dendra, meaning tree). A dendrimer is technically a polymer.
In computer applications, early research suggests that dendrimers can be used to create ultra-low dielectric constant materials, which can lead to breakthroughs in semiconductor performance.
