    Abstract: One embodiment of an micromechanical device includes a first contact surface, a moveable component having a second contact surface, and a coating of liquid or solid lubricant on at least one of the contact surfaces, where the second contact surface interacts with the first contact surface during device operation, and a gas-phase lubricant is disposed between the first contact surface and the second contact surface, where the gas-phase lubricant is adapted to increase the usable lifetime of the liquid or solid lubricant coating on the contact surfaces. One advantage of the disclosed device is that a gas-phase lubricant has a high diffusion rate and, therefore, is self-replenishing, meaning that it can quickly move back into a contact region after being physically displaced from the region by the contacting surfaces of the device during operation. Consequently, the gas-phase lubricant used with conventional solid or liquid lubricants is more reliable than solid or liquid lubricants used alone in preventing stiction-related device failures.

    Abstract: Embodiments of the present invention generally relate to a device that has an improved usable lifetime due to the presence of a lubricant that reduces the likelihood of stiction occurring between the various moving parts in an electromechanical device. Embodiments of the present invention also generally include a device, and a method of forming a device, that has one or more surfaces or regions that have a volume of lubricant disposed thereon that acts as a ready supply of “fresh” lubricant to prevent stiction occurring between interacting components found within the device. In one aspect, components within the volume of lubricant form a gas or vapor phase that reduces the chances of stiction-related failure in the formed device. In one example, aspects of this invention may be especially useful for fabricating and using micromechanical devices, such as MEMS devices, NEMS devices, or other similar thermal or fluidic devices.

    Abstract: A microelectromechanical systems (MEMS) device utilizing an aluminum fluoride layer as an etch stop is disclosed. In one embodiment, a MEMS device includes a first electrode having a first surface; and a second electrode having a second surface facing the first surface and defining a gap therebetween. The second electrode is movable in the gap between a first position and a second position. At least one of the electrodes includes an aluminum fluoride layer facing the other of the electrodes. During fabrication of the MEMS device, a sacrificial layer is formed between the first and second electrodes and is released to define the gap. The aluminum fluoride layer serves as an etch stop to protect the first or second electrode during the release of the sacrificial layer.
