This volume contains most of the papers presented at the Montréal Workshop on Polymer Metallization, held at the École Polytechnique, Montréal, Québec, June 27-29, 2001. The Workshop offered a forum for the presentation of papers by experts in the field of polymer metallization and ancillary topics. The purpose of this volume is to highlight new findings in the areas of new instrumentation, low permittivity materials, polymer metallization, barrier layers and adhesion enhancement. The intent of this volume is to bring those in the field of polymer metallization up to date, as did the previous volume in this series, published over a decade ago. The papers stress the recent finding that the metallization initially deposits onto low permittivity polymers in the form of clusters. Low permittivity polymers are explored, as are several instrumental methods for evaluating cluster dimensions and exploring cluster behavior. The morphology and chemistry of barrier layer formation sre presented, as are new methods of metal adhesion.
