Abstract:
PURPOSE: A semiconductor device prevents the deformation and collapse of storage electrodes by forming a continuous support pattern including a contact part and a connection part on the storage electrodes. CONSTITUTION: A lower interlayer insulating film (70) and an etch-stop layer (80) are successively formed on a substrate (1). Multiple storage electrodes (115) separated from each other are formed on the substrate. A continuous support pattern (145) is formed on the storage electrodes. The continuous support pattern includes a contact part (135) and a connection part (140). A storage dielectric (155) is formed on the storage electrodes and the continuous support patterns. A plate electrode (160) is formed on the storage dielectric.

Abstract:
A semiconductor device and a fabricating method thereof are provided to effectively control a threshold voltage of a recess channel array transistor by uniformly forming an impurity region only under a trench. An active region(115) is defined in a substrate(110), and then trenches(130) are formed in the active region. A material film pattern comprising impurity ion is formed under the active region, and then the impurity ion is diffused to form an impurity region(150) which contacts the material film pattern. The material film pattern is removed, and then an insulating layer pattern(160) is formed along an inner surface of the trench. A conductive pattern(170) is filled in the trench. The step of forming the material film pattern comprises forming a spacer on a sidewall of the trench and etching a bottom surface of the trench using the spacer as an etch mask to form a recess region.
