    摘要: A method of fabricating a suspended structure. First, a substrate including a photoresist layer hardened by heat is provided. Subsequently, the hardened photoresist layer is etched so as to turn the photoresist layer into a predetermined edge profile. Thereafter, a structure layer is formed on parts of the substrate and parts of the photoresist layer. Next, a dry etching process is performed so as to remove the photoresist layer, and to turn the structure layer into a suspended structure.

    摘要: A method of forming a suspended structure is disclosed. Initially, a substrate is provided. A patterned first sacrificial layer and a patterned second sacrificial layer are formed on a front surface of the substrate. The second sacrificial layer has an opening exposing a part of the substrate and a part of the first sacrificial layer. A structural layer is formed covering the abovementioned sacrificial layers. Thereafter, a lift-off process is performed to remove the second sacrificial layer and define the pattern of the structural layer. A first etching process is performed on a back surface of the substrate utilizing the first sacrificial layer as an etching barrier and a through hole is formed under the first sacrificial layer. A second etching layer is performed to remove the first sacrificial layer and a suspended structure is thereby formed.

    摘要: First, a device wafer having a substrate layer and a device layer is provided. Then, a first mask pattern is utilized to remove the device layer uncovered by the first mask pattern. Subsequently, a medium layer is formed on the surface of the device wafer, and the medium layer is then bonded to a carrier wafer. Thereafter, a second mask pattern is utilized to remove the substrate layer uncovered by the second mask pattern. Finally, the medium layer is separated from the carrier wafer, the substrate layer is bonded to an extendable film, and the medium layer is then removed.
