Abstract:
An integrated method for release and passivation of a MEMS structure, comprising:a) loading a substrate including at least one MEMS structure into a processing chamber; b) a first pretreatment step comprising contacting said substrate with a plasma generated from a first pretreatment source gas comprising oxygen and a source of hydrogen; c) a release process, during which a sacrificial layer present within said MEMS structure is removed; d) a second pretreatment step, comprising contacting surfaces of said MEMS structure with a plasma generated from a second pretreatment source gas comprising oxygen and a source of hydrogen; and e) applying a hydrophobic, self-assembled monolayer (SAM) coating to exposed surfaces of said MEMS structure.
