The present disclosure involves forming a method of fabricating a Micro-Electro-Mechanical System (MEMS) device. A plurality of openings is formed in a first side of a first substrate. A dielectric layer is formed over the first side of the substrate. A plurality of segments of the dielectric layer fills the openings. The first side of the first substrate is bonded to a second substrate that contains a cavity. The bonding is performed such that the segments of the dielectric layer are disposed over the cavity. A portion of the first substrate disposed over the cavity is transformed into a plurality of movable components of a MEMS device. The movable components are in physical contact with the dielectric the layer. Thereafter, a portion of the dielectric layer is removed without using liquid chemicals.
