摘要： A new electretization technology for a silicon microphone capable of reasonably electretizing a dielectric film of a condenser microphone formed by micromachining a silicon substrate and also capable of taking measures against variations in the microphone sensitivity caused by manufacturing variations and characteristic variations in parts is provided.A silicon microphone chip is completed and is implemented on an printed-circuit board and in this state, electretization processing is executed separately for a dielectric film in one silicon microphone chip by executing corona discharge using one needle electrode 51. More than one electretization is executed and the second or later electretization quantity is determined adaptively based on the actual measurement result of the microphone sensitivity, whereby electretization of the dielectric film is executed precisely and efficiently.
