摘要
A method of manufacturing a MEMS structure including forming a porous layer having a predetermined thickness on the top surface of a substrate over an area where a cavity is to be formed; forming the cavity by etching the substrate below the porous layer; forming a membrane layer on the top surface to seal the cavity; and forming a structure on the upper side of the membrane layer. After forming a cantilever structure on the membrane layer and etching the membrane layer, a cantilever structure is produced in a floating state over the cavity. Also, at least one inlet hole and outlet hole can be formed in the porous layer and the membrane, thereby providing a sealed fluidic channel.
