摘要 用斜置的四探针方法 ,依靠显微镜观察 ,将针尖置于微区图形的四个角区 ,用改进的范德堡公式可以得到微区的薄层电阻。文中对测准条件作了分析。并用该仪器测定了硼扩散片的薄层电阻分布。在测试过程中应用微处理器 。 The sheet resistance of microareas can be obtained from a modified Van der Pauw formula by using an inclined four probe technique. The tip of probe is put at the corner of the microarea by inspection through a microscope. The condition for precise measurement is analyzed. This instrument has been used to measure the sheet resistance distribution for Boron diffusion chip. In the measuring process, a microprocessor was used to speed up the calculation.
