Abstract :
We report on a new GaAs-Si bonding and material integration technology that can be done at room temperature with similar bonding strength as direct wafer bonding process. Because of the low bonding temperature, the material is not under stress at room temperature. When temperature rises during device processing, the GaAs film is under compression instead of tension so the film does not crack. By employing the low stress room temperature bonding technique, we demonstrated VCSELs with a threshold current of 1.2 mA under continuous-wave condition.
