Wire bonding is a method of making interconnections between an integrated circuit (IC) or other semiconductor device and its packaging during semiconductor device fabrication. Wire bonding can also be used to connect an IC to other electronics or to connect from one printed circuit board (PCB) to another, although these are less common.
The bonding settings for the most established metals are following (for 200 mm wafers): [1] Aluminium (Al) bonding temperature can be from 400 to 450 °C with an applied force above 70 kN for 20 to 45 min Gold (Au) bonding temperature is between 260 and 450 °C with an applied force above 40 kN for 20 to 45 min Copper (Cu)
The name "tight binding" of this electronic band structure model suggests that this quantum mechanical model describes the properties of tightly bound electrons in solids. . The electrons in this model should be tightly bound to the atom to which they belong and they should have limited interaction with states and potentials on surrounding atoms of the sol
