Die Attach: (Also known as Die Mount or Die Bond) is the process of attaching the silicon chip to the die pad or die cavity of the support structure (e.g., the leadframe) of the semiconductor package.
Gold Wire Ball Bonding:
Wire bonding, is the process of providing electrical connection between the silicon chip and the external leads of the semiconductor device using very fine bonding wires. The wire used in wirebonding is usually made either of gold (Au) or aluminum (Al), although There are two common wirebonding processes: Au ball bonding and Al wedge bonding
Wedge Bonding :
Copper Bonding: Cu wirebondingis starting to gain a foothold in the semiconductor manufacturing industry
