Abstract:
A method of producing a semiconductor device using high intensity pulsed radiation, comprising:providing a plastic substrate that can be damaged by said high intensity pulsed radiation, providing at least one semiconductor layer operatively connected to said plastic substrate that can be damaged by said pulsed radiation, providing a layer of highly reflective material for radiation protection operatively connected to said at least one semiconductor layer and said plastic substrate that can be damaged by said pulsed radiation, said layer of highly reflective material for radiation protection being located between said at least one semiconductor layer and said plastic substrate that can be damaged by said pulsed radiation, and wherein said layer of highly reflective material for radiation protection is a multi-layer of the materials HfOx and SiO2, and processing said semiconductor device using said high intensity pulsed radiation by irradiating said at least one semiconductor layer, whereby said layer of highly reflective material for radiation protection reflects said high intensity pulsed radiation and prevents said plastic substrate from being damaged.
