WebBridgeman) method. The wafer size has been enlarged from 2 inch to 6 inch in diameter. However, the crystal growth process of both GaAs and InP is based on the melt growth. These materials are melted at a high temperature and cooled and solidified below the melting point so that a solid single crystal ingot grows from a small seed crystal Webexpansion ~TCE! of GaAs and Si!. The backside of the entire GaAs substrate is then removed by an appropriate thinning process so that only the epitaxial III–V structure remains bonded onto the top surface of the BiCMOS wafer. After this stage of the process flow the temperature can rise up to 400°C because the constraint of the different ...
