Abstract:
PURPOSE: A method for forming a semiconductor device is provided to re-crystallize amorphous silicon areas of damaged areas, thereby enhancing electrical features. CONSTITUTION: A second insulation layer(44) is formed on a first polycrystalline silicon layer. A second polycrystalline silicon layer is formed on the second insulation layer. A second polycrystalline silicon pattern exposes a surface of the second insulation layer. A first amorphous area is formed on a side of the second polycrystalline silicon pattern. The second oxide exposing the surface of the first polycrystalline silicon layer is formed. A first polycrystalline silicon pattern exposes a surface of the first insulation layer. The exposed first insulation layer is eliminated to form a first insulation pattern which exposes a surface of a semiconductor substrate.
Abstract:
Provided are a semiconductor device and a method for manufacturing the same. The semiconductor device includes lower electrodes arranged two-dimensionally, a dielectric layer covering the surfaces of the lower electrodes, and a capacitor including an upper electrode on the dielectric layer, a first support pattern which is connected to the lower sidewalls of the lower electrodes and has a first opening, and a second support pattern which is connected to the upper sidewalls of the lower electrodes and has a second opening. The vertical distance between the first support pattern and the second support pattern may be greater than that between the bottom surface of the lower electrode and the first support pattern.
Abstract:
According to the present invention, a method of fabricating a semiconductor device is to provide a substrate where a first region having a pattern layer and a second region having a photo key are defined. A silicon layer is formed in the first and second regions on the substrate. A hole exposing the photo key part where the photo key of the second region is formed, is formed by patterning the silicon layer. A burying oxide layer is formed to fill a hole exposing the photo key part. By using the photo key formed in the lower part of the burying oxide layer, the silicon layer is patterned to form a silicon pattern layer. [Reference numerals] (AA) Second region; (BB) First region
Abstract:
PURPOSE: A semiconductor device including a strained semiconductor region, a manufacturing method thereof, and an electronic system including the same are provided to improve etch selectivity by applying a chemical dry etch method to an isotropic dry etch method. CONSTITUTION: A gate pattern(120) is formed on a substrate(110). An amorphous silicon region is formed by injecting IV or VIII group dopants into the substrate. A gate spacer(150) is formed in the sidewall of the gate pattern. A first cavity(160) is formed by firstly etching the substrate and the amorphous silicon region. A second cavity(162) is formed by secondly etching the substrate. A strained semiconductor region is formed in the second cavity.
