摘要： Micromachined ultrasonic transducers having a self-assembled monolayer formed on a surface of a sealed cavity are described. A micromachined ultrasonic transducer may include a flexible membrane configured to vibrate over a sealed cavity, and the self-assembled monolayer may coat some or all of the interior surfaces of the sealed cavity. During fabrication, the sealed cavity may be formed by bonding the membrane to a substrate such that the sealed cavity is between the membrane and the substrate. An access hole may be formed through the membrane to the sealed cavity and the self-assembled monolayer is formed on surface(s) of the sealed cavity by introducing precursors into the sealed cavity through the access hole.

摘要： Micromachined ultrasonic transducers having pressure ports are described. The micromachined ultrasonic transducers may comprise flexible membranes configured to vibrate over a cavity. The cavity may be sealed, in some instances by the membrane itself. A pressure port may provide access to the cavity, and thus control of the cavity pressure. In some embodiments, an ultrasound device including an array of micromachined ultrasonic transducers is provided, with pressure ports for at least some of the ultrasonic transducers. The pressure ports may be used to control pressure across the array.

摘要： A system and method for corrosion problems in magnetic media resulting from moisture penetrating through the carbon layer into the magnetic layer by diffusion or other methods are overcome by processing the carbon overcoat to stop and/or inhibit the moisture penetration. The process involves removing moisture channels from protective overcoats of thin film magnetic media by irradiating the protective overcoat with ultraviolet (UV) radiation in an inert hydrophobic chemical environment. Afterwards, the thin film magnetic media can be removed into ambient atmosphere where it is coated with a lubricant.
