Abstract:
An RF diode, comprising:a high-ohmic silicon substrate;a well that is doped n-conductive or p-conductive, the well formed in the high-ohmic silicon substrate;a silicon epitaxial layer formed only over a first subregion of a surface of the well, the layer having the same conductivity type as the well;a first Schottky contact layer formed in the silicon epitaxial layer;a second Schottky contact layer formed in a second subregion of the surface of the well which is located next to the first subregion, the second Schottky contact layer being in spaced adjacent relationship to both the silicon epitaxial layer and the first Schottky contact layer; andfirst and second contact metallizations formed on the first and second Schottky contact layers, respectively.
