“…Although there are still concerns about reliability and mechanical stress issues, this technique could be helpful to develop the interconnection technology for the advanced packaging where high-density joint interconnection is required. Additionally, more stable and more flexible nanostructured templates with the suitable coefficient of thermal expansion (CTE) would be a good candidate reducing the joint stress for the practical application [22,23].…”

As electronic products become more functional, the devices are required to provide better performances and meet ever smaller form factor requirements. To achieve a higher I/O density within the smallest form factor package, applying nanotechniques to electronic packaging can be regarded as a possible approach in microelectronic technology. Sn-3.0 wt% Ag-0.5 wt% Cu (SAC305) is a common solder material of electrical connections in microelectronic devices. In this study, SAC305 alloy nanowire was fabricated in a porous alumina membrane with a pore diameter of 50 nm by the pressure casting method. The crystal structure and composition analyses of SAC305 nanowires show that the main structure of the nanowire is β-Sn, and the intermetallic compound, Ag3Sn, locates randomly but always appears on the top of the nanowire. Furthermore, differential scanning calorimetry (DSC) results indicate the melting point of SAC305 alloy nanowire is around 227.7 °C. The melting point of SAC305 alloy nanowire is significantly higher than that of SAC305 bulk alloy (219.4 °C). It is supposed that the non-uniform phase distribution and composite difference between the nanowires causes the change of melting temperature.

properties because of their special struc ture. When the materials reach a nano meter size, the electrical, optical, magnetic, and other properties of the materials will be altered greatly because of the small size effect, quantum size effect, sur face and boundary effects, and Coulomb blockade effect. [1] Currently, nanomaterials have been widely applied in many fields, including computers, catalysis, sensors, energy, and environmental protection. [2][3][4][5][6][7][8][9][10][11] As the demand increases, people aspire to fabricate nanomaterials with greater prop erties. Many methods have been used to improve the properties of nanomaterials, including doping, surface reconstruc tion, semiconductor composite, and metal nanoparticle embedding. [12][13][14][15][16][17][18][19][20] These days, ion beam techniques, including ion implantation, irradiation, and focused ion beam (FIB), have been extensively used to modulate the properties of nanomaterials. Moreover, ion beam techniques are regarded as a promising technique for doping and surface modification. Compared with doping during growth and diffusion, ion implantation is more controllable and reproducible. In addition, ion implantation is also an effective method for embedding nanoclusters in body materials. Moreover, ion irradiation is an effective method to modulate the morphology and surface structure of the mate rials. Therefore, via using this technique, various properties of nanomaterials can be tailored. FIB is typically used for the in situ study of ionirradiated materials. Figure 1 shows the applications of ion beam techniques for nanomaterial surface modification.Ion implantation, as an ion beam technique, has been extensively applied to the modulation of nanomaterial sur faces. Moreover, the technique has also been extensively used in the field of microelectronics. Ion implantation has replaced diffusion as a doping method to introduce dopants into the semiconductors. As an industrial technique, it exhibits high controllability and accuracy. In contrast to other doping strat egies, almost all elements can be introduced into the target materials by ion implantation and it does not introduce other impurity elements. In addition, ion implantation is not restricted by the solid solubility of elements in the mate rials. Ion implantation can be described as a collision process Nanomaterials have gained plenty of research interest because of their excellent performance, which is derived from their small size and special structure. In practical applications, to acquire nanomaterials with high performance, many methods have been used to modulate the structure and components of materials. To date, ion beam techniques have extensively been applied for modulating the performance of various nanomaterials. Energetic ion beams can modulate the surface morphology and chemical components of nanomaterials. In addition, ion beam techniques have also been used to fabricate nanomaterials, including 2D materials, nanoparticles, and nanowires. Compared with conventional metho...

Silver nanowires (AgNWs) have great potential to be used in the flexible electronics industry for their applications in flexible, transparent conductors due to high conductivity and light reflectivity. Those applications always involve size which strongly affects the optical and electrical properties of AgNWs. AgNWs of mean diameter 70 nm and mean length 12.5 μm were achieved by the polyol solvothermal method. Sonication-induced scission was used to obtain the small size AgNWs. The relationship between the size of AgNWs and the ultrasonic time, ultrasonic power, and concentration of AgNWs were studied. The results show that the length of AgNWs gradually reduces with the increase of the ultrasonic time and ultrasonic power, and with the decrease of concentration of AgNWs. Meanwhile, there is an existence of a limiting length below which fragmentation of AgNWs no longer occurs. Further, the mechanics of sonication-induced scission for the fragmentation of AgNWs was discussed.
