|Design and Synthesis of Mesoporous Nano-Silver-Based Die Attach Material for High Power Electronics|
|Keywords: preparation, Ag nanorods, attach materials|
|With the breakthrough of the replacement of silicon by a wide band-gap semiconductor, such as SiC, GaN with high operational temperature and voltage in power semiconductor device, the design and synthesis of adhesive die attach materials ( applied to adhere the die to substrate) are also undergoing a revolution. Among of nanoparticles silver-based material is expected to be an excellent candidate due to its high thermal and electrical conductibility. In the work, we synthesize Ag particles with different aspect ratio and form a kind of new nano-Ag-based paste with and without nanoparticles. The mesoporous structure based on the Ag-paste is fabricated by various sintering process. The structure, thermal and electrical conductibility, and the joint strength of Ag layer are evaluated and discussed in detail in present work.|
