Abstract
A ferroelectric capacitor configuration is configured with at least two different coercitive voltages. A first electrode structure having a surface which forms at least two levels is firstly produced. A layer of ferroelectric material of varying thickness is deposited over the first electrode by spin coating. A second electrode structure is subsequently formed on the layer of ferroelectric material.
