    Abstract: An isolation method for a single crystalline silicon microstructure using a triple layer structure is disclosed. The method includes forming the triple layer composed of an insulation layer formed over an exposed surface of the silicon microstructure, a conductive layer formed over the entire insulation layer, and a metal layer formed over a top portion of the microstructure; and partially etching the conductive layer to form electrical isolation between parts of the microstructure. The method does not require a separate photolithography process for isolation, and can be effectively applied to microstructures having high aspect ratios and narrow trenches. Also disclosed are single crystalline silicon microstructures having a triple layer isolation structure formed using the disclosed method.

    Abstract: A method for forming a micro cavity is disclosed. In the method for forming the cavity, a first layer is formed on a silicon layer and a trench is formed in the silicon layer by selectively etching the silicon layer. A second and a third layers are formed on the trench and on the silicon layer. Etching holes are formed through the third layer by partially etching the third layer. A cavity is formed between the silicon layer and the third layer after the second layer is removed through the etching holes. Therefore, the cavity having a large size can be easily formed and sealed in the silicon layer by utilizing the volume expansion of the silicon or the poly silicon layer. Also, a vacuum micro cavity can be formed according as a low vacuum CVD oxide layer or a nitride layer formed on the etching holes which are partially opened after the thermal oxidation process by controlling the size of the etching holes concerning the other portion of the poly silicon layer.

    Abstract: PURPOSE: A method for forming a micro cavity structure hermetically sealed with a planar silicon oxide layer on a silicon substrate is provided with a simplified process and an improved planarity. CONSTITUTION: In the method, the silicon substrate(1) is selectively etched to form a plurality of narrow trenches in a region where a cavity(6) will be formed. The first silicon oxide layer is then formed in the trenches by the first thermal oxidation. Next, a portion of the first silicon oxide layer growing on a surface of the silicon substrate(1) is removed by etch. After that, a polysilicon layer is deposited on an entire resultant structure and then selectively etched to form a plurality of small apertures exposing the region of the cavity(6). Thereafter, the first silicon oxide layer is removed by wet etch through the apertures in the polysilicon layer, so that the cavity(6) is formed in the silicon substrate(1). Next, by the second thermal oxidation, the polysilicon layer is turned into the planar silicon oxide layer(2), while the apertures are clogged up by cubical expansion.
