    摘要: An in-situ compressed specimen of copper interconnection micro column, which is a circular metal column formed in a PDMS hole, includes: a specimen part and a fixed end part for fixing the specimen; wherein the fixed end part is a circular or square plate structure, the specimen part is an upper part of the fixed end part; a main body of the present invention is of micron order, a forced direction of the specimen is consistent with a growth direction of the metal column. A method of electroplating copper column by adopting PDMS as template substrate is applied to overcome a problem that TSV is corrosive to the copper column during a silicon etching process so as to affect a mechanical property accuracy test, the method is advanced in shortening test process period, achieving good reproducibility and high yield.
