Paper Abstract

The demand for increased computing power and more complex IC devices with increased functions per chip results in higher I/O count packaging. With the shrinkage in IC size and the decrease in pad pitch, the trend is moving from the current fine-pitch, such as the 50micrometers and 40micrometers . Given the tight constraint, the bonding process and bonding tool design become more complex, which produces smaller bond deformation in a repeatable manner. Those problems associated with open wire, bond liftoff, surface contamination, etc., have now become more sensitive and difficult to control.
