摘要:
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.
摘要:
The invention discloses processes for thermal transfer patterning of a nanoparticle layer and a corresponding proximate portion of a carrier layer, and optionally additional transfer layers, together onto a thermal imaging receiver. The invention is useful for dry fabrication of electronic devices. Additional embodiments of the invention include multilayer thermal imaging donors comprising in layered sequence: a base film, a carrier layer and a nanoparticle layer. The carrier layer can be a dielectric or conducting layer. When the carrier layer is a dielectric layer, the base film includes a light attenuating agent in the form of a dye or pigment.
摘要:
A process for patterning thick film electrically functional patterns using a photosensitive polymer layer. A tacky photosensitive layer (104) is applied onto a substrate surface. The photosensitive layer (104) is imaged with a pattern (106) using actinic radiation, the exposed areas (107) of the photosensitive layer become hardened and non-tacky. A subsequent application of a thick film composition sheet (101 on 102) will cause the thick film (101) to adhere to the remaining tacky areas (104). Upon peeling the sheet (102), a thick film print pattern (101) will be produced. This step is followed by a processing profile prescribed by the thick film composition used which results in a pattern having electrically functional properties. The invention also extends to a process wherein a thick film composition is recovered from a used sheet.
