  • Abstract
    A novel surface micromachined accelerometer using single crystal silicon structures is described. Trench oxide isolation is used to fabricate electrically insulating anchors. Micro-accelerometer structures are fabricated using deep RIE on inexpensive silicon substrate. Excellent performance and high yield are achieved over the temperature range utilizing a separate ASIC for signal conditioning.
