Using the infrared transmission theory, which is to say that the bonding part of the sample can make the light pass, and the un - bonding part of the sample will block the light, at the same time, the unique method of cold lamp - house is used to manufacture the instrument of testing the wafer bonding quality in order to select the high quality one for the next technical research
摘要利用紅外透射原理，即根據鍵合晶片中鍵合部分可以透光而未鍵合部分幾乎不能透光的原理，同時採用冷光源的獨特方法構建了鍵合質量測試平臺以用於初步篩選符合下一步工藝探索的高質量鍵合晶片。 -
A gaas threshold voltage automatic measurement system is designed. the sample may be 2 ", 3 " wafer. it can save the data, statistic average value and standard deviation of threshold voltage, map the gaas threshold voltage
本文建立了一套閾值電壓自動測試系統，可對半絕緣gaas單晶上製作的mesfet器件的閾值電壓進行自動測量，並給出閾值電壓的測量數據，作出閾值電壓的mapping圖，計算閾值電壓的統計平均值、標準偏差等。
