vin Test tructure for Measuring U e Specific Contact Resistivity
Abstract-A vertical Kelvin test structure, which can be used to
measure the true specific contact resistivity of a metallization system, is
proposed and studied. For this test structure, the driving current flows
“vertically,” thus the sheet resistance and current crowding effects are
eliminated and measurement on the true specific contact resistivity
becomes possible. Experimental works show that this test structure gives a
more linear relation between resistance and contact area than the
conventional six-terminal test structure.
I. INTRODUCTION
PECIFIC contact resistivity pc is one of the most important
parameters on studying interfacial properties of
metallization systems. Many test structures [1]-[4] have been
proposed to measure its value. However, due to some inherent
parasitic factors such as the sheet resistance of the diffused
layer and the lateral current crowdings (both horizontal and
vertical), the “true” value of pc is very difficult, if not
impossible, to be measured [5]-[7]. The main reason for this
difficulty comes from the fact that, for all these proposed test
structures, the current flows “horizontally” in a diffused bar
while the “vertical” interfacial contact resistance is to be
determined.
In this letter, a “vertical” Kelvin test structure to measure
the “true” specific contact resistivity is presented. For this
test structure, the driving current flows “vertically” from the
metal contact pad toward the contacted substrate. This
eliminates the current crowding effects which are inherent in
the horizontal type of test structures, and makes the determination
of the “true” specific contact resistivity possible. This
test structure can be incorporated with the six-terminal test
structure [4] to compare the measured results.
11. TEST STRUCTURE
The cross section ofthe test structure is shown in Fig. l(a)
along with its top view in Fig. l(b). The driving current I is
forced from pad 1 toward the substrate and the voltage V is
sensed between pads 2 and 3 along the implanted bar. The
vertical current flow is restricted by an isolation p-n junction.
For this structure, it can be seen that the current flows
vertically and only through the contact window: hence the
current distribution in the contact region is uniform provided
that the contact region is metallurgically uniform. The contact
