  • Publication number: 20080191210
    Abstract: Stray light in an oblique direction penetrates a channel part of a thin-film transistor, which sometimes causes light leakage current. This phenomenon becomes more pronounced in the case of using an optical system with high intensity, leading to deterioration in an image quality. To prevent the light that possibly penetrates an equivalent optical waveguide from reaching the channel part, on the condition that a first insulating layer is set to have a layer-thickness t (nm) and a refraction index n, a relation is to be expressed by the following expression. t<(0.61×?)/(n×sin ?) A value of ? is set to a lower limit 400 (nm) of a visible light wavelength and a value Lc (nm) is set to a distance between an end of a light-shielding layer and an end of a channel region. With those values, an expression of nt2/244 (nm)<Lc (nm) is set up.

In this manner, a self-aligned source or drain contact can be formed through the non-protective dielectric material(s) to contact either the source or the drain region, while the dielectric cap protects the first gate conductor during formation of the source or drain contact opening and thereby prevents shorting between the first gate conductor and the source or drain contact to be formed.
