Wafer bonding of gallium arsenide on ...

Three-inch (100) gallium arsenide wafers were bonded to ( 1/line{1} 02) sapphire in a micro-cleanroom at room temperature under hydrophilic or hydrophobic surface conditions. Subsequent heating up to 500 °C increased the bond energy of the GaAs-on-sapphire (GOS) wafer pair close to the fracture energy of the bulk material. The bond energy was measured as a function of the temperature.
