Method for measuring an electric property of a test sample

The method may be used for measuring an electric property of a magnetic tunnel junction used in an embedded MRAM memory for example. The method uses a multi point probe with a plurality of probe tips for contacting a designated area of the test sample, which is electrically insulated from the part of the test sample which is to be tested. Electrically connections are placed underneath the magnetic tunnel junction and goes to the designated area.

Apparatus and method for testing semiconductor devices

The invention is a test system for testing silicon wafers or packaged devices. The system includes a tester having multiple testing stacks that each hold a vertical stack of test engines, data buffers, pin drivers, and other resources, which are electrically connected on one side to a wafer or DUT and on the other side to a test host computer via fast data links. Each testing stack is disposed on a top side of a wafer contactor electrically connected to a wafer or a load board electrically connected to a DUT. The system includes a cooling system to remove heat during operation. The system minimizes the data signal path between the pads of the devices being tested and the pin drivers of the tester, the test engines, and the test host computer. High performance is possible by the connection of bottom of each testing stack directly to the wafer contactor.

The first strengthening board includes a top surface, a bottom surface, and a mounting hole. An inner wall of the mounting hole is formed with an inner flange. The fixed frame is disposed on the top surface of the first strengthening board and surrounds the mounting hole. The probe module is disposed in the mounting hole and includes an outer flange including a physical region and multiple gap regions. The physical region abuts against the inner flange of the first strengthening board. The slidable frame is disposed on an inner wall of the fixed frame and is slidable between a released position and a fixed position. Multiple pressing portions are disposed on an inner wall of the slidable frame.

Pressure relief valve

A method of testing an integrated circuit of a device is described. Air is allowed through a fluid line to modify a size of a volume defined between the first and second components of an actuator to move a contactor support structure relative to the apparatus and urge terminals on the contactor support structure against contacts on the device. Air is automatically released from the fluid line through a pressure relief valve when a pressure of the air in the fluid line reaches a predetermined value. The holder is moved relative to the apparatus frame to disengage the terminals from the contacts while maintaining the first and second components of the actuator in a substantially stationary relationship with one another. A connecting arrangement is provided including first and second connecting pieces with complementary interengaging formations that restricts movement of the contactor substrate relative to the distribution board substrate in a tangential direction.
