Latest Patents

Iwaseki's latest patents focus on a method of fabricating an ultra-small condenser microphone. In this invention, a semiconductor substrate containing multiple MEMS microphones is positioned opposite a discharge electrode while being adhered to a sheet. The electretization of a dielectric film within the MEMS microphone is achieved by irradiating the film with ions generated from a corona discharge of the discharge electrode. This process occurs under a predetermined potential difference applied to the fixed electrode and the vibration film. By relatively moving the semiconductor substrate and the discharge electrode, electretization is performed successively on each MEMS microphone. This innovative approach allows for the use of low-cost and simple fabrication equipment, ultimately enhancing productivity.
