摘要:
A method for fabricating a semiconductor device, in which a lifting phenomenon can be prevented from occurring in forming an amorphous carbon film on an etched layer having tensile stress. According to the invention, since a compression stress on the etched layer or the amorphous carbon film can be reduced or a compression stress film is formed between the etched layer or the amorphous carbon film to prevent a lifting phenomenon from occurring and thus another pattern can be formed to fabricate a highly integrated semiconductor device.

A method of manufacturing flash memory devices increases a coupling ratio by increasing the height of a floating gate externally projecting from an isolation layer. A portion of the isolation layer between the floating gates is etched so that a control gate to be formed subsequently is located between the floating gates. Accordingly, an interference phenomenon can be reduced.

A semiconductor device includes a first barrier metal layer and a second barrier metal layer, a third barrier metal layer, and a metal line. The first barrier metal layer and the second barrier metal layer are formed and on a top surface of an insulating layer over a semiconductor substrate on the bottom surface of trenches formed in the insulating layer. The third barrier metal layer is formed on sidewalls of trenches. The metal line gap-fills the trenches. In a method of forming a metal line of a semiconductor device, trenches are formed within an insulating layer over a semiconductor substrate. A first barrier metal layer and a second barrier metal layer are formed on a bottom surface of the trenches and on a top surface of the insulating layer. A third barrier metal layer is formed on sidewalls of trenches. A metal line gap-fills the trenches.

In a method of fabricating a flash memory device, after an isolation trench is formed, a bottom surface and sidewalls of the trench are gap-filled with a HARP film having a favorable step coverage. A wet etch process is performed such that the HARP film remains on the sidewalls of a tunnel dielectric layer, thereby forming a wing spacer. Accordingly, the tunnel dielectric layer can be protected and an interference phenomenon can be reduced because a control gate to be formed subsequently is located between floating gates.

Provided is an air flow structure for a dryer, which includes a drying fan, and an air guide having a bent and inclined shape so as to guide flow of a circulation air discharged by the drying fan. This air flow structure improves air circulation flow in the dryer, reduces noise generated in the drying procedure, and increases air volume introduced into a drying duct.
