Display screen with thin silicon substrate - has anti-reflection coating and bonds thinned layer to mon:oxide layer with epoxy resist and bonds to glass with coating

摘要

The display has a thin substrate, which has an anti-reflection coating. The layer formed on the substrate is masked to prevent attack from the contents of a dilution bath, which will only attack the exposed sections. The thinned plate (44) is made from silicon and has a refractive index of approx.3.6. Under that there is a layer (46) of silicon monoxide with a thickness equal to approx. one quarter of a wavelength. The refractive index is between that of the bonding agent such as epoxy and silicon. This layer is followed by a layer of glass (48) with a refractive index of approx. 1.5. The glass has a coating that reduces the refractive index.
