Abstract:
1. A probe assembly for use in a probe station having a chamber for receiving a sample to be measured, the probe assembly comprising: a probe body; a probe tip; and a resilient member connected to the probe body, wherein the probe body is supported in the chamber by a probe arm having a longitudinal axis, wherein the probe tip is connected to the resilient member, wherein the probe tip is configured to contact a sample in the chamber at a location to be measured, wherein the longitudinal axis of the probe arm is parallel to the sample; and wherein the resilient member decouples the probe tip from the probe body such that the probe tip resists movement from said location on the sample during movement of the probe body in a direction substantially parallel to said longitudinal axis of the probe arm, said movement of the probe body resulting from contraction or expansion of the probe arm due to a temperature change in the chamber.
