    摘要: A diaphragm structure for a MEMS device includes a through-hole formed so as to penetrate from an upper surface to a bottom surface of a substrate; and a vibrating electrode film formed on the upper surface of the substrate so as to cover the through-hole. An opening shape of the through-hole in the upper surface of the substrate is substantially hexagonal.

    摘要: A MEMS device includes a first insulating film formed on a semiconductor substrate, a vibrating film formed on the first insulating film, and a fixed film above the vibrating film with an air gap being interposed therebetween. The semiconductor substrate has a region containing N-type majority carriers. A concentration of N-type majority carriers in a portion of the semiconductor substrate where the semiconductor substrate contacts the first insulating film, is higher than a concentration of N-type majority carriers in the other portion of the semiconductor substrate.
