An extraordinary combination of material science, manufacturing processes, and innovative
thinking spurred the development of SiGe heterojunction devices that offer a wide array of …

The RF coplanar probe is a popular tool for launching high-frequency signals onto and off of
a wafer. Physically contacting the die, it establishes a crucial link between the test system …

It is well known that, in the millimeter (mm-wave) and sub-mm-wave range, on-wafer S-
parameter measurements are often inaccurate and suffer from serious systematic artifacts. In …

To reduce noise in measurements obtained by probing a device supported on surface of a
thermal chuck in a probe station, a conductive member is arranged to intercept current …

This article presents an advanced calibration method for solving the error terms due to probe-
probe leakage in an on-wafer test system. A new 12-term error model for the on-wafer test …

of the surfaces of the elastic membrane is distorted. A conductive probe includes a beam …

Short-Open-Load-Reciprocal (SOLR) has been used as a calibration technique when the
realization of a good thru line is difficult. This may happen in on-wafer environments (eg …
