Abstract
In one embodiment, a method of treating a surface of a Micro-Electromechanical System (MEMS) device reduces or eliminates performance degradation due to charge migration and accumulation. Briefly, the method may include treating a dielectric surface of the MEMS device to replace hydroxyl groups with electrically neutral molecules, thereby converting the dielectric surface from a hydrophilic to a substantially hydrophobic nature. A MEMS device having a surface treated using the aforementioned method is also disclosed.
