20090115039High Bond Line Thickness For Semiconductor Devices - Die attach methods used in making semiconductor devices and the semiconductor devices resulting from those methods are described. The methods include providing a leadframe with a die attach pad, using boundary features to define a perimeter on the die pad, depositing a conductive material (such as solder) within the perimeter, and then bonding a die containing an integrated circuit to the die pad by using the conductive material. The boundary features allow an increased thickness of conductive material to be used, resulting in an increased bond line thickness and increasing the durability and performance of the resulting semiconductor device.05-07-2009
20110037153HIGH BOND LINE THICKNESS FOR SEMICONDUCTOR DEVICES - Die attach methods used in making semiconductor devices and the semiconductor devices resulting from those methods are described. The methods include providing a leadframe with a die attach pad, using a boundary feature(s) containing a bond wire to define a perimeter on the die attach pad, depositing a conductive material (such as solder) within the perimeter, and then attaching a die containing an integrated circuit device to the die attach pad by using the conductive material. The boundary feature(s) allow an increased thickness of conductive material to be used, resulting in increased bond line thickness and increasing the durability and performance of the resulting semiconductor package. Other embodiments are described.02-17-2011
