摘要： In the present invention, a plurality of ultra-small condenser microphones is formed on a same substrate. Then, charges are fixed to a dielectric film provided in each of the ultra-small condenser microphones. After an amount of deposited charges in each of the dielectric films is inspected, the substrate whereon the plurality of ultra-small condenser microphones is formed is diced so that each of the ultra-small condenser microphones is separated. Thus, at least the step of fixing charges is performed in a substrate state where the plurality of ultra-small condenser microphones is formed on the same substrate. Therefore, the present invention contributes to enhancement of productivity in an assembly process of the ultra-small condenser microphone and reduction in equipment costs.

摘要： In the present invention, a semiconductor substrate wherein a plurality of MEMS microphones is formed is disposed opposed to a discharge electrode in a state of being stuck on a sheet. Electretization of a dielectric film provided in the MEMS microphone is performed by irradiating the dielectric film between a fixed electrode and a vibration film provided in the MEMS microphone with ions resulting from a corona discharge of the discharge electrode in a state that a predetermined potential difference is applied to the fixed electrode and the vibration film and fixing charges based on the ions to the dielectric film. The electretization is successively performed to each MEMS microphone on the semiconductor substrate by relatively moving the semiconductor substrate and the discharge electrode. Therefore, electretization of the dielectric film in the MEMS microphone chip is realized using a low-cost and simple fabricating equipment and productivity can be enhanced.
