Microminiature patterned metal on medical grade balloons
A thin walled balloon formed in polymer tubing has a patterned metal layer on its outer surface, created by physical vapor deposition (PVD). The pattern is defined by a stencil mask assembled around the balloon, with the balloon inflated therein. The PVD occurs without deforming or degrading the polymer material of the balloon, by actively pulling heat away from the balloon a) by forming the stencil mask out of metal; b) by providing a metal heat conduction path away from the balloon to a heat sink, such as outside the vacuum chamber, and/or c) by flow of a cooling fluid within the balloon during the PVD process. Proper PVD process parameters are selected to minimize heat generation, such as having argon pressure in the range of 0.8 to 1.2 milli-torr and generating the plasma at a power of less than about 200 watts/ square inch of effective target surface area.

Electrically and Magnetically Enhanced Ionized Physical Vapor Deposition Unbalanced Sputtering Source
An electrically and magnetically enhanced ionized physical vapor deposition (I-PVD) magnetron apparatus and method is provided for sputtering material from a cathode target on a substrate, and in particular, for sputtering ceramic and diamond-like coatings. The electrically and magnetically enhanced magnetron sputtering source has unbalanced magnetic fields that couple the cathode target and additional electrode together. The additional electrode is electrically isolated from ground and connected to a power supply that can generate positive, negative, or bipolar high frequency voltages, and is preferably a radio frequency (RF) power supply. RF discharge near the additional electrode increases plasma density and a degree of ionization of sputtered material atoms.
