Goal(s)
- Give a general view of assembly processes in microelectronics
- Present the main phenomena that intervene in these peocesses such as wetting, diffusion and interfacial reactivity
- Provide the basic notions of the physico-chemistry of the interfaces involved during the different assembly processes in the electronic industry
- Apply these knoledges to real packaging cases in electronic inductry
- Provide notions of selection criteria of materials for electrolyte, cathode, anode, interconnects
- Provide notions of durability in solid state electrochemistry
- Give notions of economical aspects and technological bolts and tendencies
Content(s)
I) Packaging (10h)
- The role of packaging in microelectronics.
- IC packaging, technologies (WB - wire-bonding, FC - flip chip, TAB - Tape Automated Bonding).
- Packaging families (SMP, THP,..), types (BGA, PQA, SIP, PGA,...) and packages (plastic, ceramic).
- Materials used in packaging (advantages and limits).
- Microsystem packaging.
- Description and study of physico-chemical and mechanical phenomena intervening in packaging process (thermodynamics, reaction kinetics, wetting,...).
- Study of particular cases of packaging.
II) Durability (6h)
- Principle of Solid Oxide Fuel Cell (SOFC)
- Packaging : from elementary cell to stack
- Economical aspects, present technological bolts and tendencies
- Main role of used materials: electrolyte, cathode, anode, interconnects (advantages and limits)
- Problems of SOFC operating at high temperature (durability)
- Solutions: SOFC operating at intermediate temperature
