The interest in the use of laser-scribing for the manufacturing of conductive patterns in electronics has been growing in the last years since this technique enables: i) inherent lithography without the use of masks, ii) a green-electronics approach, limiting the use of hazardous agents or reactives and iii) a cost-effective fabrication process with a very limited number of fabrication steps. In this contribution, we apply such a technique for obtaining RF devices on different substrates and using different precursors as either laser-activated or scribed conductive materials. The role of the laser influence on the photothermal process and the optimization of the electrical conductivity will be discussed. The techniques are applied for the realization of different samples of antennas in the UHF RFID band. The preliminary obtained results show interesting perspective for the future adoption of the laser-based production of flexible electronics RF devices.

Abstract

The interest in the use of laser-scribing for the manufacturing of conductive patterns in electronics has been growing in the last years since this technique enables: i) inherent lithography without the use of masks, ii) a green-electronics approach, limiting the use of hazardous agents or reactives and iii) a cost-effective fabrication process with a very limited number of fabrication steps. In this contribution, we apply such a technique for obtaining RF devices on different substrates and using different precursors as either laser-activated or scribed conductive materials. The role of the laser influence on the photothermal process and the optimization of the electrical conductivity will be discussed. The techniques are applied for the realization of different samples of antennas in the UHF RFID band. The preliminary obtained results show interesting perspective for the future adoption of the laser-based production of flexible electronics RF devices.
