Patent ID: 8310266

Claim:
A device for characterizing an electro-optical performance of a semiconductor component in a vacuum or controlled atmosphere, comprising: a chamber containing a vacuum or controlled atmosphere; a measuring head equipped with conductive probes designed to come into contact with the electrical interfaces of the component and connected to a data processing system in order to determine the electro-optical performance; a staging fixture support intended to accommodate the component, the staging fixture being capable of being cooled and being moved in an upward and downward translational movement making it possible to bring the electrical interfaces of the component into contact with the tip of the measuring probes of the measuring head; wherein the staging fixture has bumps and the component is positioned so that the component is in contact with the bumps; wherein, in the area of each of these bumps, the staging fixture accommodates two positioning grids which are capable of sliding relative to each other and cooperating with each other to define pockets suitable for accommodating the component to be characterized; and wherein the measuring head is also equipped with mechanical probes which press against the inactive zone of the component in order to hold the component in place on the staging fixture.
