Differential Hall Effect Metrology (DHEM) is an electrical depth profiling technique that measures all critical electrical parameters through an electrically active material at sub-nanometer depth resolution. DHEM is based on the previously developed Differential Hall Effect (DHE) method. In the traditional DHE method, successive sheet resistance and Hall effect measurements on a semiconductor layer are made using Van der Pauw and Hall effect techniques. The thickness of the layer is reduced through successive processing steps in between measurements. This typically involves thermal, chemical or electrochemical etching or oxidation to remove material from the measurement circuit. This data can be used to determine the depth profiles of carrier concentration, resistivity and mobility. DHE is a manual laboratory technique requiring wet chemical processing for etching and cleaning the sample between each measurement, and it has not been widely used in the semiconductor industry. Since the contact region is also affected by the material removal process, the traditional DHE approach requires that contacts be newly and repeatedly be made to collect data on the coupon. This introduces contact related noise and reduces the repeatability and stability of the data. The speed, accuracy and, depth resolution of DHE has been generally limited because of its manual nature. The DHEM technique is an improvement over the traditional DHE method in terms of automation, speed, data stability and, resolution. DHEM technique had been deployed in a semi-automated or automated tools.
