Claim 9:
10. A semiconductor structure, comprising:
a semiconductor substrate;
a dielectric structure disposed over the semiconductor substrate;
an electrical contact electrically connected to the semiconductor substrate, sidewalls of the electrical contact surrounded by the dielectric structure;
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;
wherein the electrical contact comprises a conductive element and a dopant material having a dopant concentration equaling about 1015 atom/cm3 or from about 1015 atom/cm3 to about 1017 atom/cm3, the dopant material comprises a first dopant element, and a difference between an atomic weight of the conductive element and an atomic weight of the first dopant element is less than about 100.
