![]() 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.
