    摘要: A method for improving the accuracy of electrical test results of semiconductor wafers is described. The method introduces a non-contacting physical cleaning process prior to testing. The cleaning process removes micro-contamination on circuit contact pads that has been introduced during semiconductor wafer processing. This results in more accurate electrical probing of the semiconductor wafers.
