半导体工艺常见问题(一) - 知乎专栏
一般情况下的万用表测量电阻时不能避免接触电阻,而 四探针法,利用外侧两电流,内测两电压,有效避免了接触电阻;另外,四探针法还可以测试薄膜厚度(利用方块电阻)。 9.Substrate为什么必须对电阻进行把控? Substrate本身的电阻会影响到后续WAT(wafer accept testing)时Rds(on),其实不仅对于电阻,还有厚度,弯曲等。 10.Substrate上的 EPI 作用是什么? 11.Substrate 为什么需要掺杂? 12.Substrate的掺杂类型有哪些? 13.N型半导体中掺As和P有 …

0.5pp在财务或者在数学上是什么意思? 是增长了0.5%,还是这次增长的百分比比上次多0.5? 对pp很疑惑。 同问,比如本周76%,上周71%,我该怎么说? 本周比上周提升了5pp? 对pp很 …
一文搞懂四线(开尔文)测电阻法 - 知乎 - 知乎专栏
今天我们来一起学习一下 四线测电阻法,也叫 四端点测量技术 、四端测试法、 开尔文测量法。 对应的英文是:Four-terminal sensing (4T sensing), 4-wire sensing, or 4-point probes method。 本文中,我们将会学习何时以及为啥要使用四线测电阻。 要想理解四线测电阻得先理解两线测电阻,两线测电阻时电路图如下: 万用表测量电阻的步骤如下: 流入到待测电阻的电流大小与万用表的量程相关。 量程越大,输出电流越小,反之,量程越小,输出电流越大。 对于非常低的量 …
