| 要獲得高的剝離強度，除了薄膜與銅良好的界面作用外，還需要薄膜具有較高的內(nèi)聚強度。A的低剝離強度產(chǎn)生的原因正是因為其較低的內(nèi)聚強度。此處“內(nèi)聚強度”與“拉伸強度”兩個概念并不完全相同。因為，薄膜的拉伸強度是薄膜沿薄膜平面的破壞強度，而剝離時的內(nèi)聚強度則主要是垂直于薄膜平面方向的破壞強度。通常的薄膜都存在分子鏈沿薄膜平面的較大程度的取向，因此，兩個方向的強度不能等同，這也就是說，薄膜的拉伸強度大并不表示剝離時其內(nèi)聚強度就大。而薄膜與銅箔界面附近存在的“弱邊界層”會加劇薄膜在這一區(qū)域的內(nèi)聚強度與本體拉伸強度的差別。因此，此處只能說明邊界區(qū)域的內(nèi)聚強度小而不能說其拉伸強度小。 |

To obtain a high peel strength, in addition to a good interface with the copper film role, but also need to have a higher film cohesive strength. A low peel strength causes precisely because of its low cohesive strength. Here "cohesive strength" and "tensile strength" two concepts are not identical. Because the tensile strength of the film along the film plane of the film breaking strength, and peel strength when the cohesion of the film is mainly in the plane perpendicular to the direction of the breaking strength. Usually the molecular chain of the film there is a greater degree along the film plane orientation, therefore, can not be the same strength in both directions, which means that Film strip tensile strength does not mean that the cohesive strength when its big. The copper thin film near the interface with the existence of "weak boundary layer" will film in the region increased cohesive strength and bulk tensile strength difference. Therefore, here only shows that the cohesive strength of the boundary region is small and can not say that the tensile strength of small. |

To obtain high peel strength,there must be have the good interface effect between film and copper as well as the higher cohesive energy of the film. The reason why A have a low peel strength is the lower cohesive energy of A. In this case, "cohesive strength" and "tensile strength" are not exactly identical in concept. Because the tensile strength of film is the strength that film collapses along the film plane, and cohesive strength in the peel process is primaryy the strength that film collapses perpendicular to the film plane. The strength of the two directions are not identical because there exist the molecular chain which has greater degree of orientation along the film plane in the ordinary film, in other words, the high tensile strength of film doesn't mean the high cohesive in the peel process. Weak boundary layer in the vicinity of the interface between film and copper aggravate the difference between the cohesive strength and tensile strength of the film in this region. So, here we can only consider that boundary region has a lower cohesive rather than than lower tensile strength. 僅供參考。 |
