  • Publication number: 20200062587
    Abstract: A semiconductor arrangement and method of formation are provided. The semiconductor arrangement includes a MEMS device in a MEMS area, where a first metal layer is connected to a first metal connect adjacent the MEMS area and a cap is over the MEMS area to vacuum seal the MEMS area. A first wafer portion is over and bonded to the first metal layer which connects the first metal connect to a first I/O port using metal routing. The first metal layer and the first wafer portion bond requires 10% less bonding area than a bond not including the first metal layer. The semiconductor arrangement including the first metal layer has increased conductivity and requires less processing than an arrangement that requires a dopant implant to connect a first metal connect to a first I/O port and has a better vacuum seal due to a reduction in outgassing.
