In this paper , the circuit used for testing sheet resistance is designed using single chip processor . additionally , we have expressed van der pauw function as a polynomial form through local and global reversal development by using the normalized polynomial match , being convenient not only for programming , but also for sheet resistance testing when using van der pauw and rymaszewski methods 本文还利用单片机系统设计了薄层电阻测试电路,对于程序中用到的范德堡隐函数,利用非线性反演和规范化拟合的方法推导出其多项式显函数形式。这不仅给对我们编写程序提供了方便,也为使用范德堡法和rymaszewski法测量薄层电阻提供了便利。
