The method includes applying an adhesive on a substrate and mounting a chamber container thereon by using a mounter; curing the adhesive holding the chamber container; applying an adhesive on the chamber container and mounting a micro electro mechanical system (MEMS) chip thereon by using a mounter; curing the adhesive holding the MEMS chip; and attaching the substrate on which devices are mounted to a case, wherein a back chamber formed by the chamber container is added to a back chamber of the MEMS chip. Therefore, a silicon condenser microphone fabricated by using the method may have improved sensitivity by increasing the small back chamber space of the a micro electro mechanical system (MEMS) chip itself and reduced noise including total harmonic distortion (THD)."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Silicon condenser microphone having an additional back chamber and a fabrication method therefor","description":"A fabrication method of a silicon condenser microphone having an additional back chamber.
