    摘要: A method for manufacturing a semiconductor device having a movable portion includes the steps of: forming a trench on a semiconductor layer so that the trench reaches an insulation layer; and forming a movable portion by etching a sidewall of the trench so that the semiconductor layer is separated from the insulation layer. The steps of forming the trench and forming the movable portion are performed by a reactive ion etching method. The insulation layer disposed on the bottom of the trench is prevented from charging positively in the step of forming the trench. The insulation layer disposed on the bottom of the trench is charged positively in the step of forming the movable portion.

    摘要: A method of manufacturing a semiconductor device is provided. The device is manufactured with use of an SOI (Silicon On Insulator) substrate having a first silicon layer, an oxide layer, and a second silicon layer laminated in this order. After forming a trench reaching the oxide layer from the second silicon layer, dry etching is performed, thus allowing the oxide layer located at the trench bottom to be charged at first. This charging forces etching ions to impinge upon part of the second silicon layer located laterally to the trench bottom. Such part is removed, forming a movable section. For example, ions to neutralize the electric charges are administered into the trench, so that the electric charges are removed from charged movable electrodes and their charged surrounding regions. Removing the electric charges prevents the movable section to stick to its surrounding portions.

    摘要: A plasma etching method, which can form concave parts and/or opening parts on a substrate by performing etching at a high speed and does not damage an element part formed on the surface of the substrate, is disclosed. On a semiconductor substrate with one surface as an element part forming surface and the other surface having an insulating film thereon as an etching surface are formed concave parts and/or opening parts by means of etching by applying a high-frequency electric power to a reactive gas and generating plasma thereby. The substrate is disposed on an electrode having grounded electric potential with the insulating film positioned on the lower side and a conductive part material having grounded electric potential is disposed around the substrate. When one end of the conductive part material is contacted with the side of the etching surface of the substrate, electric charge generated on the surface of the substrate moves to the conductive part material, and the electric potential of the substrate is lowered.

    摘要: Plural semiconductor chips such as acceleration sensor chips formed on the first surface of a substrate are separated into individual pieces by dicing the substrate from the second surface thereof. A groove surrounding each sensor chip, along which the sensor chip is diced out, is formed at the same time the sensor chip is formed on the first surface. Before dicing, a protecting sheet covering the first surface is pasted along the sidewalls and the bottom wall of the groove. The groove is made sufficiently wide to ensure that the protecting sheet is bent along the walls of the groove without leaving a space between the groove and the protecting sheet. Thus, dicing dusts generated in the dicing process are prevented from being scattered and entering the sensor chip.
