Comparison of Test Structures Used for the Measurement of Low Resistive Metal-Semiconductor Contacts,
Abstract
Specific contact resistivity rho (c) (O low-sq cm), which can be extracted from measured contact resistance Rc (O low), is a commonly used measure of metal-semiconductor contact quality. It is independent of current flow and contact geometry, and depends only on the transport properties of the metal to semiconductor junction. Unfortunately, extraction of rho (c) obtained from test structures differing in size of design often disagree by as much as an order of magnitude primarily because simple 1-D models which are used to extract the value of rho (c) can not account for fringing resistance associated with the 2-D nature of the current distribution around the contact.
