Abstract
An ultra-high speed photonic sintering method consisting of flash white light (FWL) combined with near infrared (NIR) and deep UV light irradiations was developed to fabricate a SrTiO3 (STO) thin film for application in electro-vibration touch panels. The STO thin film was sintered on PEN by FWL irradiation at room temperature under ambient conditions, which is a dramatically simple and ultrahigh speed fabrication process compared to the conventional high temperature (600 °C-900 °C) thermal sintering process. The effects of the FWL irradiation conditions (energy density, pulse numbers, and pulse duration) on the dielectric constant of the sintered STO thin films were evaluated. Furthermore, the effects of NIR and deep UV irradiation during the FWL sintering process were also investigated.
