Abstract:
1. A device formed by a process comprising: providing a substrate; forming a sacrificial layer over the substrate; forming a field layer around the sacrificial layer; planarizing the sacrificial layer and the field layer; forming a component over the planarized sacrificial layer and the planarized field layer, the component having a first electrode and a second electrode and a single crystal wafer disposed between the first electrode and the second electrode, wherein the component includes anchors disposed substantially over the field layer; and releasing the sacrificial layer with an etchant having a selectivity for the sacrificial layer, thereby forming a cavity beneath the component, where the component freely moves within the cavity during operation of the device, wherein the etchant does not release the field layer and the component such that the field layer remains below and in contact with the anchors and the anchors remain stationary during operation of the device.
