Abstract
There is disclosed a semiconductor device having a PN junction terminating at a surface and passivated by a multi-layer passivant system comprising a first layer of semi-insulating material over the surface, a layer of dielectric material over the first layer and a second layer of semi-insulating material over the dielectric layer. Preferably, the first and second layers are oxygen doped polycrystalline silicon and the dielectric layer is either silicon dioxide of frit glass fused to the first layer.
