Described is an apparatus which comprises: a die having a first side and a second side opposite to the first side; a die backside film (DBF) or die attach film (DAF) disposed over the first side of the die; and a fluorocarbon layer disposed over the DBF or DAF. Described is a method which comprises: applying a die backside film (DBF) over a first side of a die, wherein the die has a second side which metal bumps; and applying a plasma polymerization process to treat the DBF with a fluorocarbon plasma.

Apparatus and method for mitigating surface imperfections on die backside film using fluorocarbon material

A method for singulating dies from a wafer includes laser scribing a continuous line on each side of the die, and laser ablating an area adjacent the laser scribed continuous line on each side of the die. The laser ablations in the area adjacent the laser scribed continuous line on each side of the die being spaced from one another. The method also includes sawing the laser abated area adjacent the continuous line. A method for singulating dies from a wafer includes laser scribing a first continuous line, laser scribing a second continuous line spaced apart from the first continuous line, and laser scribing a third continuous line. The third continuous line positioned between the first continuous line and the second continuous line. The third continuous line overlaps the second continuous line and the third continuous line.
