发明名称 Surface-micromachined absolute pressure sensor and a method for manufacturing thereof
摘要 The present publication discloses a capacitive pressure sensor structure, in particular for measurement of absolute pressure, and a method for manufacturing the sensor. The sensor comprises at least one fixed electrode (3), and at least one movable electrode (6, 7) electrically isolated from said fixed electrode (3) and spaced apart (10) from said fixed electrode (3). According to the invention, a portion of said movable electrode (6, 7) is formed from a porous polycrystalline silicon layer (6) that in a finished component remains as an integral portion of said flexibly movable electrode (6, 7).
