Abstract
Embodiments of the present invention generally relate to a MEMS device that is anchored using the layer that is deposited to form the cavity sealing layer and/or with the layer that is deposited to form the pull-off electrode. The switching element of the MEMS device will have a flexible or movable portion and will also have a fixed or anchor portion that is electrically coupled to ground. The layer that is used to seal the cavity in which the switching element is disposed can also be coupled to the fixed or anchor portion of the switching element to anchor the fixed or anchor portion within the cavity. Additionally, the layer that is used to form one of the electrodes may be used to provide additional leverage for anchoring the fixed or anchor portion within the cavity. In either situation, the movement of the flexible or movable portion is not hindered.
