Abstract :
GaInAsP surfaces were investigated by contact angle measurement of a water droplet to estimate their hydrophilicity. The most hydrophilic surface of GaInAsP was obtained by the O/sub 2/ plasma activation process. Wafer direct bonding was successfully achieved between O/sub 2/ plasma activated GaInAsP and garnet crystals.
