Effect of hexamethylenetetramine on surface smoothness of electroplated copper coating
نویسندگان
چکیده
In this paper, hexamethyltetramine is introduced into the electroplating bath to improve surface morphology of electrodeposited copper. The cyclic voltammetry (CV) and dynamic polarization curves are used study effect Cu(Ⅰ) on electrochemical behaviors solution. After implementing copper experiment, scanning electron microscope (SEM) X-ray diffraction (XRD) explore influence Surface crystal plane orientation results show that 5ppm 7.5ppm can solve problem loose uneven electroplated layer caused by Cu(Ⅰ).

15 صفحه اولEffect of passivation on stress relaxation in electroplated copper films
The present study investigated the effect of passivation on the kinetics of interfacial mass transport by measuring stress relaxation in electroplated Cu films with four different cap layers: SiN, SiC, SiCN, and a Co metal cap. Stress curves measured under thermal cycling showed different behaviors for the unpassivated and passivated Cu films, but were essentially indifferent for the films pass...
