A wafer probe station system for reliability testing of a semiconductor wafer. The wafer probe station is capable of interfacing with interchangeable modules for testing of semiconductor wafers. The wafer probe station can be used with different interchangeable modules for wafer testing. Modules, such as probe card positioners and air-cooled rail systems, for example, can be mounted or docked to the probe station. The wafer probe station is also provided with a front loading mechanism having a rotatable arm that rotates at least partially out of the probe station chamber for wafer loading.

Semi-automatic prober

A wafer temperature measurement tool for measuring the surface temperature of a semiconductor wafer. The tool can be used to measure temperature on different parts of the wafer to provide a high resolution temperature distribution map. The tool includes an internal calibrated weight that is slidably disposed within a tool body. A temperature sensor is attached to the bottom of the weight. Ceramic stands are attached to the bottom of the tool body. Gravity pulls down on the weight such that the temperature sensor contacts the wafer when the ceramic stands of the tool body are placed on the wafer.

Wafer temperature measurement tool

A probe card is vertically mounted generally perpendicular to a wafer undergoing life tests in a heated environment to limit exposure of the probe card to heat from the wafer chuck. The probe card and probe head assembly are mounted on a support rail which has one or more channels for the flow of cool air to a probe head assembly and the probe card, while it shields the flex cable from the hot chuck. The cool air flow disrupts convective hot air flow upwards from the heated chuck to the probe card and probe head and facilitates cooling of the probe card and probe head.
