電(dian)阻(zu)率是反映(ying)半導體材料導電(dian)性(xing)能的重要(yao)參(can)數(shu)之一。測量電(dian)阻(zu)率的方(fang)(fang)法(fa)很多(duo),四(si)(si)探針(zhen)(zhen)(zhen)法(fa)是一種廣泛采用的標準方(fang)(fang)法(fa)。它的優點是設備簡單、操作方(fang)(fang)便,精確度(du)(du)高,對樣品的形狀無嚴格要(yao)求(qiu)。直(zhi)線型四(si)(si)探針(zhen)(zhen)(zhen)。四(si)(si)根探針(zhen)(zhen)(zhen)的針(zhen)(zhen)(zhen)尖在同一直(zhi)線上,并(bing)且間距(ju)相等(deng),都是S,一般采用0.5mm的間距(ju),不(bu)同的探針(zhen)(zhen)(zhen)間距(ju)需要(yao)對測量結(jie)果做相應的校正。一般四(si)(si)探針(zhen)(zhen)(zhen)電(dian)阻(zu)率(電(dian)導率)測試儀(yi)均已配置厚(hou)度(du)(du)的修正,通(tong)過厚(hou)度(du)(du)數(shu)值(zhi)的設置,計算出(chu)不(bu)同的樣品厚(hou)度(du)(du)對電(dian)阻(zu)率的影(ying)響。
