    Abstract: A method of avoiding stiction during vapor hydrofluoride (VHF) release of a microelectromechanical system (MEMS) or nanoelectromechanical system (NEMS) composed of a mechanical device and a substrate is described. A silicon nitride layer is provided between the substrate and a sacrificial oxide layer and/or between a device layer and the sacrificial oxide layer, and/or on a side of the device layer facing away from the sacrificial oxide layer, and converted to thicker ammonium hexafluorosilicate with VHF while simultaneously removing a portion of the sacrificial oxide. The ammonium hexafluorosilicate acts as a temporary support, shim, wedge, or tether which limits device movement during fabrication and is later removed by sublimation under heat and/or reduced pressure.
