Abstract:
Methods and semiconductor devices for bonding a first semiconductor device to a second semiconductor device include forming metal pads including a textured microstructure having a columnar grain structure at substantially the same angular direction from the top surface to the bottom surface. The textured crystalline microstructures enables the use of low temperatures and low pressures to effect bonding of the metal pads. Also described are methods of packaging and semiconductor devices.

Claim (Index 12):
The method of  claim 1 , wherein the second metal pad having the textured crystalline microstructure is formed by depositing a sacrificial stress locking layer onto a metal for defining the second metal pad prior to annealing; annealing the metal to form the textured crystalline microstructure; and removing the sacrificial stress locking layer prior to bonding to form the second metal pad.
