Quantitative microstructure characterization of Ag nanoparticle sintered joints for power die attachment
The samples of sintered Ag joints for power die attachments were prepared using paste of Ag nanoparticles at 240 °C and 5 MPa for 3 to 17 minutes. Their microstructural features were quantitatively characterized with scanning elec-tronic microscopy, transmission electron microscopy, X-ray diffractio...

| description | The samples of sintered Ag joints for power die attachments were prepared using paste of Ag nanoparticles at 240 °C and 5 MPa for 3 to 17 minutes. Their microstructural features were quantitatively characterized with scanning elec-tronic microscopy, transmission electron microscopy, X-ray diffraction and image analysis method. The resulting nor-malized thickness, pore size and porosity decreased, and grain size increased with increasing the sintering time. A time dependence of the form t1/n with n close to 2 or 3 can be further derived for the kinetics of the thinning, densification and grain growth within the sintered Ag joints. |
