The compositions are useful for dry fabrication of electronic devices. Also provided are patterned multilayer compositions comprising one or more base film(s), and one or more patterned metal layers, including EMI shields and touchpad sensors.

Disclosed is a method for making a metal pattern with high conductivity comprising providing a patterned substrate comprising a patterned catalyst layer on a base substrate by a thermal imaging method followed by plating to provide the metal pattern. The metal patterns provided are suitable for electrical devices including electromagnetic interference shielding devices and touchpad sensors.

Composition and method for providing a patterned metal layer having high conductivity

The invention provides metal compositions, including silver compositions, and thermal imaging donors prepared with the compositions. The donors are useful for thermal transfer patterning of a metal layers and optionally, a corresponding proximate portion of an additional transfer layer onto a thermal imaging receiver. The compositions are useful for dry fabrication of electronic devices. Also provided are patterned multilayer compositions comprising one or more base film(s), and one or more patterned metal layers, including EMI shields and touchpad sensors.

A pellicle comprising a thin, durable film of substantially uniform thickness which absorbs less than 10% light at wavelengths between 190 and 820 nanometers, tautly adhered to one edge of an enclosed support frame, said thin film comprising amorphous fluoropolymers having a refractive index between 1.24 and 1.41. Pellicles of this type are dust defocusing covers for photomasks and reticles used to project patterns onto light sensitive substrates such as photoresist-coated semiconductor wafers which are used in the manufacture of integrated circuits.
