Coatings barrier comparisons

Experiments like those described above have been performed to evaluate sodium ion barrier properties of Hitachi PIQ and DuPont PI 2540 polyimide films. Also included in the comparison were silicon nitride coatings plasma deposited in both tensile and compressive stress modes. The structure of the samples is illustrated in Figure 9. N-type, (111) oriented silicon substrates were cleaned and oxidized in dry oxygen ambient at 1100°C to form a 1060 A Si02 film. Wafers intended for polyimide characterization were coated with an organic silane film (gamma glycidal amino propyl trimethoxysilane) to promote adhesion of the polyimide to the oxide surface. The polyimide resins were spun onto the wafers at speeds to produce final... [Pg.161]

Reported examples are mostly related to corrosion studies the particular problems in relating Volta potential differences as measured with a SKP and local corrosion potentials have been treated in detail [131]. The effect of barrier layers and metal-surface pretreatment has been investigated [136, 137]. In a study of the effect of a corrosion protection primer containing the intrinsically conductive polyaniline (CORRPASSIVTM) [128], the positive shift of the potential of the steel surface coated with this primer in comparison to the surface coated with a standard primer is evident, and the positive effect of the primer on the extent of the (much narrower) delamination zone is obvious (see below). [Pg.1846]
