Abstract:
A semiconductor structure and method of fabricating the same are disclosed. In an embodiment, the structure includes a first substrate having a buried plate or plates in the substrate. Each buried plate includes at least one buried plate contact, and a plurality of deep trench capacitors disposed about the at least one buried plate contact. A first oxide layer is disposed over the first substrate. The deep trench capacitors and buried plate contacts in the first substrate may be accessed for use in a variety of memory and decoupling applications.
