1. An apparatus comprising:
- a testing setup having a plurality of probes configured to be aligned with a plurality of through-silicon vias (TSVs) of a device under test, wherein a bottom terminal of the probe is thinner than a remaining portion of the probe; and
a plurality of conductive devices, each of which connects two adjacent probes, wherein the plurality of conductive devices and the plurality of probes form a conductive chain through a removable contact between the probe and the device under test when the device under test is placed within the apparatus.

Abstract
A three dimensional (3D) integrated circuit (IC) testing apparatus includes a plurality of connection devices. When a device under test (DUT) such as an interposer or a 3D IC formed by a plurality of 3D dies operates in a testing mode, the 3D IC testing apparatus is coupled to the DUT via a variety of interface channels such as probes. The connection devices and a variety of through silicon vias (TSVs) in the DUT form a TSV chain so that an electrical characteristic test of the variety of TSVs can be tested all at once.
