摘要: A probe position monitoring structure includes a first common line, a second common line, a contact portion configured, and a reference zigzag structure. The contact portion includes a first zigzag structure, a second zigzag structure, a third zigzag structure, and a fourth zigzag structure. A first end of the first zigzag structure, a first end of the fourth zigzag structure, and a first end of the reference zigzag structure are directly connected with the first common line. A first end of the second zigzag structure, a first end of the third zigzag structure, and a second end of the reference zigzag structure are directly connected with the second common line. The reference zigzag structure is disposed between the first zigzag structure and the second zigzag structure. A line width of the reference zigzag structure is equal to a line width of the first zigzag structure.

摘要: Micro and nanoscale probes are used in the semiconductor and thin film materials industries to test wafers and samples. Probes supply and measure signals to and from the sample. Signals could be electrical, mechanical, chemical, optical, or photonics. Techniques of capacitance response signal, intensity response signal, photocurrent response signal, piezoresistance response signal, a high frequency response signal, elongated image response signal, contrast response signal, electrical response signal, resonance response signal, current response signal, and/or current-in-plane response signal could be used to determine when the probe tips are in proximity or contact a sample surface.

摘要: A probe card includes a circuit board, a fixing member, and a plurality of probes. The fixing member is fixed on the circuit board and has a through opening therein. The fixing member has opposite first and second sidewalls defining the through opening. Each of the probes includes an arm portion and a tip portion. One end of the arm portion is connected to the circuit board. The tip portion extends from the arm portion. The arm portions of the probes extend in substantially a same direction inclined to a direction perpendicular to the first sidewall of the fixing member in a top view.

摘要: Aspects of the present disclosure describe a voice coil actuated leaf spring prober that advantageously may be operated to probe every individual device (device under test—DUT) comprising a contemporary wafer. The prober according to aspects of the present disclosure includes one or more probe needles attached in an electrically isolated arrangement to an end of a horizontal-U-shaped, recurved, leaf spring arrangement. The prober includes—for example—a voice coil actuator positioned within the horizontal-U-shaped portion of the leaf spring which—when operated—results in leaf spring displacement and probe needle movement such that it may mechanically/electrically contact the DUT.

摘要: Disclosed herein is an integrated heater and measurement (IHM) device comprising heating-sensing element(s) and heating-sensing circuit(s). A heating-sensing element generates heat and determines the temperature of the IHM device. In some embodiments, the heating-sensing element may operate in a plurality of modes: heating mode, sensing mode, and/or off mode. A controller may dynamically adjust the properties of the operation mode and/or time periods based on the determined temperature. The adjusted properties may include the duration of the heating mode, the ON time for a heating-sensing element, etc. The controller may adjust the duration of heating mode based on the temperature difference between the determined temperature and a set point temperature, such as decreasing the duration of the heating mode when there is a low temperature difference, and increasing the duration of the heating mode when there is a high temperature difference.
