摘要:
A semiconductor device includes a substrate including a cell region and a connection region. A stack is disposed on the substrate. A vertical channel structure penetrates the stack in the cell region. The stack includes electrode patterns and insulating patterns which are alternatingly and repeatedly stacked on the substrate. Each of the electrode patterns may extend in a first direction and include a pad portion. The pad portion is positioned in the connection region. The pad portion includes a first sidewall and a second sidewall that extend in the first direction on opposite sides of the pad portion. The first sidewall has a recessed portion that is recessed in a second direction crossing the first direction toward the second sidewall.

A double pattern method of forming a plurality of contact holes in a material layer formed on a substrate is disclosed. The method forms a parallel plurality of first hard mask patterns separated by a first pitch in a first direction on the material layer, a self-aligned parallel plurality of second hard mask patterns interleaved with the first hard mask patterns and separated from the first hard mask patterns by a buffer layer to form composite mask patterns, and a plurality of upper mask patterns in a second direction intersecting the first direction to mask selected portions of the buffer layer in conjunction with the composite mask patterns. The method then etches non-selected portions of the buffer layer using the composite hard mask patterns and the upper mask patterns as an etch mask to form a plurality of hard mask holes exposing selected portions of the material layer, and then etches the selected portions of the material layer to form the plurality of contact holes.

In a semiconductor device including a transistor having an embedded gate, and methods of manufacturing the same, a substrate is divided into first and second regions. A gate trench is formed in the first region, a first gate structure partially fills the gate trench and a passivation layer pattern is provided inside the gate trench and positioned on the first gate structure. A first source/drain is provided adjacent to sidewalls of the first gate structure. A second gate structure is provided in the second region and has a silicon oxide layer, a conductive layer pattern and a metal silicide layer pattern stacked on the conductive layer pattern. A second source/drain is provided adjacent to sidewalls of the second gate structure. Defects due to formation of reactants may be reduced in a formation process of the above-described semiconductor device, improving reliability and operating characteristics.
摘要:
A method of forming a semiconductor device is provided. The method includes preparing a semiconductor substrate to include a cell region and a peripheral region and forming a first mask layer on the semiconductor substrate. First hard mask patterns that are configured to expose the first mask layer are formed on the first mask layer in the cell region. A second mask layer that is configured to conformably cover the first hard mask patterns is formed. A second hard mask pattern is formed between the first hard mask patterns, wherein the second hard mask pattern is configured to contact a lateral surface of the second mask layer. The second mask layer interposed between the first hard mask patterns and the second hard mask pattern is removed. A plurality of trenches are etched in the semiconductor substrate of the cell region using the first hard mask patterns and the second hard mask pattern as a mask.
摘要:
A bread maker comprising: a main body; an oven having a surface coated with a ceramic material, and being accommodated in the main body; a door provided in a front of the main body to open and close the oven; and upper heaters and lower heaters respectively disposed in upper and lower parts of the oven and the door. The oven is coated with a ceramic material so that an inner surface of the oven does not become deformed due to a high temperatures, and so that an inner surface of the oven that is stained or coated with bread ingredients can be easily cleaned. The upper heaters are inclined downward, thereby enhancing heating efficiency. Further, the oven components are detachable so that a damaged part of the oven can be separately replaced.
