摘要:
In an apparatus and method for magnetic field assisted electrochemical discharge machining (ECDM), the magneto hydrodynamic (MHD) effect is utilized to improve the thickness of bubble film and the electrolyte circulation so as to enhance the machining accuracy and efficiency. Since charged ions in a magnetic field are induced by Lorenz force to move, and the electrolysis bubbles generated in the ECDM process are suffused with electrification ions on their surfaces, the electrolysis bubbles can be forced to move in the direction of the magnetic field without the need of mechanical disturbance. The present invention can be widely applied in the micro-machining of non-conductive brittle materials of different dimensions and shapes, comprising the forming of microchannels and microholes on a biochip, and in the micro-opto-electro-mechanical system (MOEMS) and various kinds of micro-machining fields. The machined surface is smooth and does not require a second time machining.

A vertical transistor structure comprises a substrate, a plurality of pillars formed on the substrate and spaced from each other, a plurality of trenches each formed between two adjacent pillars, a protection layer formed on the surface of a first side wall and the surface of a second side wall of the trench, a first gate and a second gate respectively formed on the protection layer of the first side wall and the second side wall, and a separation layer covering a bottom wall of the trench. The present invention uses the separation layer functioning as an etch stopping layer to the first gate and the second gate while being etched. Further, thickness of the separation layer is used to control the distance between the bottom wall and the first and second gates and define widths of the drain and the source formed in the pillar via ion implantation.

A self-aligned wet etching process comprises the steps of: etching a substrate having an etch protection layer on a surface thereof to form a plurality of trenches spaced from each other; and sequentially forming an insulating layer, an etch stop layer and a primary insulator in each trench, wherein the primary insulator is filled inside an accommodation space surrounded by the etch stop layer. During the wet etching process, the etch stop layer protects the primary insulator from being etched, whereby is achieved anisotropic wet etching. Further, the present invention expands the contact areas for electrically connecting with external circuits and exempts the electric contactors formed on the contact areas from short circuit caused by excessively etching the primary insulators.
