They are manufactured in six inched wafers, utilizing DRIE techniques and patented processes. An applied force or acceleration (including gravity) causes a capacitance shift in a differential capacitor, which is converted to a pulse density modulation by an integrated ASIC. The XY sensing element is a differential capacitor fabricated in single crystal silicon with a high aspect ratio thereby offering excellent performance in sensitivity and linearity. The sensing element is enclosed in a hermetic wafer-level package using wafer to wafer bonding. This allows it to be assembled in different types of packaging including low cost over-molded plastic packages. Dies are fully probed and inspected and can be shipped in waffle pack.
