A fixture to connect your DUT to the MFIA.Zurich Instruments LabOne LabVIEW API's latest version.LabVIEW Full or Professional License, v.The LabVIEW template discussed here provides a good start, as most of the code is developed and you only need to develop the temperature controller program with the third-party protocol. A short BNC cable connects Aux Output 1 to Aux Input 1. This blog post addresses point 3, so that you can add the necessary third-party products to the overall system.įigure 1: The MFIA with the MFITF fixture. This signal is added to the AC test signal for measuring the resulting capacitance transient waveform. The MFIA covers the second point the first point is also covered, as the LabOne ® software's Threshold Unit generates the square wave with a defined offset and frequency and routes this analog waveform to the Aux Input (see Figure 1). A cryostat and a programmable temperature controller to set the right thermal conditions.An impedance analyzer to record the transient of the capacitance signal.A function generator to apply the bias voltage pulse train to the material under test.The three basic building blocks of a custom DLTS system are: The MFIA can form the heart of such a system. A custom DLTS system can provide flexibility and enable new modes of DLTS. DLTS solutions are in high demand because of new and emerging semiconductor materials that need to be tested. On the market you can find several DLTS turnkey solutions, typically tailored to specific test recipes, and standalone measurement devices (such as the Boonton 7200 that has been discontinued though). Following the positive voltage pulse, the junction is again reverse biased, charges are gradually emitted and cause a change in capacitance. The semiconductor junction is initially reverse biased to deplete the bulk of mobile charge carriers subsequently, the reverse bias voltage is briefly set to zero by a positive voltage pulse and the empty traps are filled.

The technique involves measuring capacitance transients at different temperatures. It also includes ideas for independent code for the control of a third-party temperature controller.ĭeep level transient spectroscopy (DLTS) is a powerful and commonly used technique to investigate the concentration and carrier binding energy of defects in semiconductors. This blog post describes how to get started with writing a LabVIEW™ code to control the MFIA Impedance Analyzer for DLTS measurements.
