Multi-layer deposition system

For touch panel displays of mobile electronic devices, transparent conductive oxides (TCO), mostly ITO are sputter deposited on hard-coated PET. To match the reflection appearance of sputtered ITO areas with etched free areas of uncoated substrate, “index-matching” layer stacks of high index and low index dielectrics are reactively sputtered onto the substrate. For sputter coated window films for automotive glass applications, multi-layer stacks of oxides and metals reduce the heat load from the sun. Color shift layer stacks for anti-counterfeiting are produced at high speed with TOPBEAM™ 1100.
