Description
Technical Field
The invention belongs to the technical field of device packaging materials, and particularly relates to a silver solder paste sintering aid and a preparation method and application thereof.
Background
With the rapid development of new electronic fields such as electronic automobiles, aerospace, oil exploration and efficient energy utilization, people have further promoted the high-reliability packaging, high-density packaging, high-temperature service performance and the requirements for the electric and thermal conductivity of packaging materials. However, the conventional silicon-based semiconductor is difficult to function in a high-temperature, high-pressure and high-corrosion environment due to the limited forbidden band width, and compared with the conventional silicon-based semiconductor, a third-generation semiconductor represented by silicon carbide and gallium nitride has higher breakdown voltage, thermal conductivity, and high electron mobility and current density due to the higher forbidden band width, so that the application requirement of a chip under extreme regulation can be met. In addition, the conventional tin-based solder is difficult to meet the high-temperature service requirement of more than 250 ℃, and is easy to melt at high temperature, so that a series of chip failure phenomena such as cracking of a packaging interconnection structure, large holes, warping of a chip and the like are caused, and therefore, the development of a new advanced welding material becomes a problem to be solved urgently in the field of third-generation semiconductor application at present.
Silver materials have received much attention in the third generation semiconductor packaging field due to their high thermal conductivity and high reliability at high temperatures. In industry, silver particles are often mixed with an organic solvent, a sintering aid, and a binder to prepare a silver paste, and the silver paste is sintered to form a strong solder joint. The silver material is divided into micron-sized silver particles and nano-sized silver particles, the micron-sized silver particles are easy to process, produce and store and are not easy to agglomerate, but the micron-sized silver particles are large in size and have higher melting points, so that the micron-sized silver particles can be melted at higher temperature to complete welding, and the requirement of industrial actual production is not met. The nano particles are diffused through the crystal boundary, and compared with the traditional crystal lattice diffusion, the activation energy is required to be less and faster, and the sintering temperature is required to be relatively lower, so that the nano particles are favored in the industry at present. The nano silver soldering paste generally reduces the sintering temperature of the soldering paste by synthesizing smaller nano silver, so as to meet the industrial processing conditions, but due to the size effect, the synthesis process steps of the extremely small nano particles are complex, and the nano silver soldering paste is easy to agglomerate and difficult to store in the storage and transportation processes, so that a large amount of cost is consumed. Therefore, in the industrial preparation of the solder paste, the stability of a solder system is enhanced by methods of preparing a solvent, adding a sintering aid and the like, and the mechanical property of a sintered joint is enhanced by reducing the sintering temperature.
The traditional silver soldering paste has the advantages that the wetting angle is small during coating, the contact performance with a substrate is poor, the density of space stacking is low after coating, a large number of cavities are generated due to solvent volatilization during sintering, collapse and damage of a sintering structure can be caused, the mechanical strength of a chip is reduced, the reliability of the chip during use is influenced, although the density and the mechanical performance of a bonding joint can be enhanced to a certain extent due to the addition of sintering aids such as adhesives, the adhesives such as polymers are difficult to remove in the sintering process due to the high melting point, the conductive and heat-conducting performance of the chip can be remained in a system, and the problems of poor reliability and the like occur during high-temperature service. Research suggests that silver salts such as silver oxide, silver oxalate and silver acetate are added into a solder paste system as sintering aids, and the silver salts are heated and decomposed to form silver nanoparticles to reinforce a sintering interconnection structure, but the sintering aids have high decomposition temperature and are difficult to promote the interconnection of the sintering structure at low temperature.
Disclosure of Invention
