    • The inventive concept provides a wafer test method and a wafer test apparatus. The wafer test method can recognize the amount of residuals generated in a sidewall of the metal-containing layer pattern and the extent of corrosion of a sidewall of the metal-containing layer pattern using the measured electric resistance by supplying an electrolyte so that the electrolyte is in contact with a portion of the metal-containing layer pattern in a predetermined chip region and measuring an electric resistance between a first electrode which is electrically in contact with the other portion of the metal-containing layer pattern and a second electrode which is in contact with the electrolyte in the predetermined region. Thus, a wafer test method and a wafer test apparatus can be embodied by an in-line method without dividing a wafer into each chip.
    • 本发明的概念提供了晶片测试方法和晶片测试装置。 晶片测试方法可以通过提供电解质来确定含金属层图案的侧壁中产生的残留量以及含金属层图案的侧壁的腐蚀程度,使得电解质为 与预定芯片区域中的含金属层图案的一部分接触,并且测量与含金属层图案的另一部分电接触的第一电极和接触的第二电极之间的电阻 电解液在预定区域内。 因此,可以通过在线方式来实现晶片测试方法和晶片测试装置,而不将晶片分成每个芯片。
