    Abstract: According to an embodiment of a semiconductor device, the semiconductor device includes a micro-mechanical structure and a semiconductor material arranged over the micro-mechanical structure. A side surface of the semiconductor material includes a first region and a second region. The first region has an undulation, and the second region is a peripheral region of the side surface and decreases towards the micro-mechanical structure.

    Abstract: Methods and apparatus for forming MEMS devices. An apparatus includes at least a portion of a semiconductor substrate having a first thickness and patterned to form a moveable mass; a moving sense electrode forming the first plate of a first capacitance; at least one anchor patterned from the semiconductor substrate and having a portion that forms the second plate of the first capacitance and spaced by a first gap from the first plate; a layer of semiconductor material of a second thickness patterned to form a first electrode forming a first plate of a second capacitance and further patterned to form a second electrode overlying the at least one anchor and forming a second plate spaced by a second gap that is less than the first gap; wherein a total capacitance is formed that is the sum of the first capacitance and the second capacitance. Methods are disclosed.
