Packaging and Durability - 5PMMPAC5

I) Packaging (10h00)

• 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 (6h00)

• 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

Thermodynamics, Surfaces-Interfaces, Phase diagrams, Electrochemistry
