Ferro-electric capacitor modules, methods of manufacture and design structures. The method of manufacturing the ferro-electric capacitor includes forming a barrier layer on an insulator layer of a CMOS structure. The method further includes forming a top plate and a bottom plate over the barrier layer. The method further includes forming a ferro-electric material between the top plate and the bottom plate. The method further includes encapsulating the barrier layer, top plate, bottom plate and ferro-electric material with an encapsulating material. The method further includes forming contacts to the top plate and bottom plate, through the encapsulating material. At least the contact to the top plate and a contact to a diffusion of the CMOS structure are in electrical connection through a common wire.

A SiGe bipolar transistor including a semiconductor substrate having a collector and sub-collector region formed therein, wherein the collector and sub-collector are formed between isolation regions that are also present in the substrate is provided. Each isolation region includes a recessed surface and a non-recessed surface which are formed utilizing lithography and etching. A SiGe layer is formed on the substrate as well as the recessed non-recessed surfaces of each isolation region, the SiGe layer includes polycrystalline Si regions and a SiGe base region. A patterned insulator layer is formed on the SiGe base region; and an emitter is formed on the patterned insulator layer and in contact with the SiGe base region through an emitter window opening.
