Attachable microphone and manufacturing method therefor

A manufacturing method for an attachable microphone, the manufacturing method comprising:

• (a) a process of fabricating a substrate which includes a back chamber having a first cylindrical hollow and which includes a first frame member surrounding the back chamber and including a first polymer;
• (b) a process of fabricating a lower plate including a back plate part and a first electrode part, the back plate part including a plurality of first through holes and a back plate that includes a second polymer, the first electrode part being disposed on the back plate part and including a plurality of second through holes and a first electrode member;
• (c) a process of fabricating an upper plate including a support part, a second electrode part, and a diaphragm, the support part including a front chamber that has a second cylindrical hollow and including a second frame member which includes a third polymer and which surrounds a front chamber, the second electrode part being disposed on the support part and including a second electrode member, the diaphragm being disposed on the second electrode part and including a thin film that includes a fourth polymer;
• and
• (d) a process of fabricating the attachable microphone having a substrate/lower plate/upper plate structure by using thin film transferring,
• wherein the process (d) is a process of forming the substrate/lower plate/upper plate structure by using thin film transferring and of fabricating the attachable microphone by forming an adhesive part that includes an adhesive agent, the adhesive part penetrates the back plate part and the first electrode part, and the adhesive part respectively adheres the substrate and the support part.
