Abstract

A probing system includes a chuck configured to support a device under test (DUT); and a manipulator disposed above the chuck and including a first probe protruding from the manipulator toward the chuck, wherein the first probe includes a temperature-sensing device for sensing a temperature adjacent to a front surface of the DUT. A probing device includes a chuck; a DUT disposed over the chuck; a manipulator disposed above the DUT, wherein the manipulator includes a first probe protruding from the manipulator toward the DUT and including a temperature-sensing device for sensing a temperature, the DUT is moved toward the manipulator for sensing a temperature of the DUT by the first probe.

Claims (27)

1. A probing system comprising:

a chuck configured to support a device under test (DUT); and

a manipulator disposed above the chuck and including a first probe protruding from the manipulator toward the chuck,

wherein the first probe includes a temperature-sensing device for sensing a. temperature of a front surface of the DUT, the temperature-sensing device is surrounded by a thermal conductive member, and an end of the temperature-sensing device protrudes from the thermal conductive member.

2. The probing system of claim 1 , wherein the temperature-sensing device is disposed at an end portion of the first probe.

3. The probing system of claim 2 , further comprising a thermal shield surrounding the end portion of the first probe.

4. The probing system of claim 3 , wherein the thermal is shield includes Teflon.

5. The probing system of claim 1 , wherein the temperature-sensing device includes one of a temperature sensor, a thermistor or a resistive temperature detector (RTD).

6. The probing system of claim 1 , wherein a width of the temperature-sensing device is substantially less than 200 μm.

7. The probing system of claim 1 , wherein the temperature-sensing device includes metallic, ceramic or polymeric material.

8. The probing system of claim 1 , further comprising a second probe disposed adjacent to the first probe and configured for probing and testing the DUT.

9. The probing system of claim 1 , the thermal conductive member is configured to increase thermal conductivity of an end portion of the first probe.

10. The probing system of claim 1 , wherein the thermal conductive member is formed of conductive epoxy.

11. The probing system of claim 1 , wherein a material of the thermal conductive member includes silver (Ag) or gold (Au).

12. The probing system of claim 1 , wherein the first probe is flexible and bendable.

13. The probing system of claim 1 , further comprising an electromagnetic shield surrounding a body portion of the first probe.

14. The probing system of claim 13 , wherein a material of the electromagnetic shield includes copper (Cu).

15. The probing system of claim 1 , wherein the first probe is connected to the manipulator through a connector.

16. A probing device, comprising:

a chuck;

a device under test (DUT) disposed over the chuck; and

a manipulator disposed above the DUT, wherein the manipulator includes a first probe protruding from the manipulator toward the DUT and the first probe includes a temperature-sensing device for sensing a temperature,

wherein the DUT is moved toward the manipulator for sensing the temperature of a front surface of the DUT by the temperature-sensing device, the temperature-sensing device is surrounded by a thermal conductive member, and an end of the temperature-sensing device protrudes from the thermal conductive member.

17. The probing device of claim 16 , wherein during the sensing of the temperature, a distance between the temperature-sensing device and the front surface of the DUT is substantially less than 1 μm.

18. The probing device of claim 16 , wherein the temperature-sensing device contacts the front surface of the DUT during the sensing of the temperature.

19. The probing device of claim 16 , further comprising a second probe, wherein the front surface of the DUT is probed by the second probe, thereby the sensing of the temperature and the probing of the DUT are performed simultaneously.

20. The probing device of claim 19 , wherein the first probe and the second probe are deformed during the sensing of the temperature.
