運(yùn)用直線或方形四探針雙位測(cè)量。符合單晶硅物理測(cè)試方法國(guó)家標(biāo)準(zhǔn)并參考美國(guó) A.S.T.M 標(biāo)準(zhǔn)。利用電流探針、電壓探針的變換，進(jìn)行兩次電測(cè)量，對(duì)數(shù)據(jù)進(jìn)行雙電測(cè)分析，自動(dòng)消除樣品幾何尺寸、邊界效應(yīng)以及探針不等距和機(jī)械游移等因素對(duì)測(cè)量結(jié)果的影響，與單電測(cè)直線或方形四探針相比，大大提高精確度，Using a straight line or square four probe double bit measurement.Meet the national standard of the single-crystal silicon physical test method and consult the American measurement. Double electrical analysis of data. Automatically eliminate the factors influence on the measured results such as sample geometry size and boundary effect and probe not equidistant and moving machinery etc. Compared with the single electrical measuring linear or square four point probe. greatly improve the accuracy.
