Abstract
A method for producing wafer splitting from ion implantation into silicon after low temperature direct bonding with surface roughness that is ˜1 nm (RMS). This result is an order of magnitude smoother than the previous work (˜10 nm RMS). The key improvement in this work is the use of a low temperature bond resulting in a strong bond before the material is cut. The smooth as-split surfaces produced using a low temperature bond are very important for creation of very thin (<50 nm) silicon-on-insulator (SOI), three-dimensional bonded structures and nanostructures that are split after processing.
