- The use of SPFM (H2SO4-H2O2-HF) at low HF concentrations (10-1000 ppm) has been investigated as a pre-cleaning procedure for silicon direct bonding. This cleaning procedure can be tuned to simultaneously give hydrophilic surface properties, ensuring good bondability, and excellent electric properties, crucial for the application of direct bonding in device applications
