Abstract:
1. A capacitive dynamic quantity sensor, comprising: a first insulator having a first electrode formed thereon; a second insulator having a second electrode formed thereon; and a semiconductor having a weight formed therein, which displaces due to a dynamic quantity, a column is formed in the semiconductor so that the first electrode is electrically connected with the second electrode; the column is composed of an upper conductive portion, an intermediate insulating portion, and a lower conductive portion; an electrical connecting means which connects the upper conductive portion with the lower conductive portion is disposed on the upper portion of the column the upper portion of the column is not mechanically isolated from other columns; and the electrical connecting means disposed on the upper portion of the column is electrically isolated from other electrical connecting means disposed on upper portion of other columns.
