    摘要： First, a stationary electrode layer is formed over a semiconductor substrate and an integrated network is composed in a circuit element area around the stationary electrode layer by electrode wiring forming each circuit element. A spacer is arranged on a passivation film in plural places. A dummy island is formed in an area between the circuit element area and the stationary electrode layer area. Supply potential Vcc is applied to the dummy island and ground potential GND is applied to a P+-type separated area.

    摘要： A sound detecting mechanism capable of forming a diaphragm and a back electrode on a substrate by a simple process includes acoustic holes corresponding to perforations formed on a front surface of a substrate. A second protective film, a sacrificial layer and a metal film are laminated on the front surface in a portion corresponding to the acoustic holes. The substrate is etched from the back surface thereof to a depth reaching the acoustic holes to form an acoustic opening. Subsequently, by effecting an etching from the back surface of the substrate through the acoustic holes, the sacrificial layer is removed and a void area is formed between the diaphragm made of the metal film, the substrate and the formed perforations. The sacrificial layer that remains after the etching is used as a spacer for maintaining a gap between the back electrode and the diaphragm.

    摘要： A liquid crystal display having an injection hole post structures compatible with liquid crystal are formed in an area near an injection hole to prevent pollutants seeped from an end-sealing material from penetrating into a display area, thereby suppressing the occurrence of picture quality trouble which easily occurs in the display area. The liquid crystal display includes a first substrate 11 and a second substrate 12 which are disposed with a predetermined gap therebetween, in which liquid crystal is sealed in the gap. The liquid crystal display further includes: post structures for controlling the gap; a sealing material provided outside the display for sealing the liquid crystal in the gap, and forming the open injection hole for injecting the liquid crystal therethrough; the end-sealing material 16 for sealing the injection hole after the liquid crystal is sealed in; and injection hole post structures provided in the area near the injection hole, for dividing the injection hole 15 into a plurality of portions by using the same material as the post structures.
