Claim 0:
1. A semiconductor structure, comprising:
a semiconductor substrate;
a dielectric structure disposed over the semiconductor substrate;
a doped polysilicon contact disposed over the semiconductor substrate, sidewalls of the doped polysilicon contact surrounded by the dielectric structure, the doped polysilicon contact comprising a dopant material having a dopant concentration equaling about 1015 atom/cm3 or from about 1015 atom/cm3 to about 1017 atom/cm3;
a buffer layer, disposed on the semiconductor substrate;
a contact structure, disposed on the semiconductor substrate; and
a conductive structure, wherein a portion of the conductive structure is disposed on the contact structure, and another portion of the conductive structure is disposed on the buffer layer, wherein the conductive structure surrounds the dielectric structure.
