A semiconductor device includes an active pattern disposed on a substrate. A gate insulating film is disposed on the active pattern and extends along the active pattern. A work function adjustment pattern is disposed on the gate insulating film and extends along the gate insulating film. A gate electrode is disposed on the work function adjustment pattern. The work function adjustment pattern includes a first work function adjustment film, a second work function adjustment film that includes aluminum and wraps the first work function adjustment film, and a barrier film including titanium silicon nitride (TiSiN). A silicon concentration of the barrier film is in a range of about 30 at % or less.

Semiconductor device

A semiconductor device includes a first transistor having a first threshold voltage, and including first channels, first source/drain layers connected to opposite sidewalls of the first channels, and a first gate structure surrounding the first channels and including a first gate insulation pattern, a first threshold voltage control pattern, and a first workfunction metal pattern sequentially stacked. The semiconductor device includes a second transistor having a second threshold voltage greater than the first threshold voltage, and including second channels, second source/drain layers connected to opposite sidewalls of the second channels, and a second gate structure surrounding the second channels and including a second gate insulation pattern, a second threshold voltage control pattern, and a second workfunction metal pattern sequentially stacked.

Semiconductor devices

A semiconductor device includes a substrate and first and second gate electrodes on the substrate. The first gate electrode includes a first gate insulation film having a bottom portion on the substrate and sidewall portions extending from the bottom portion and away from the substrate defining a first trench having a first width and a first functional film filling the first trench. The second gate electrode includes a second gate insulation film having a bottom portion on the substrate and sidewall portions extending from the bottom portion defining a second trench having a second width different from the first width, a second functional film conforming to the second gate insulation film in the second trench and defining a third trench, and a metal region in the third trench. The first width may be less than the second width.

A semiconductor device includes first semiconductor patterns vertically stacked on a substrate and vertically spaced apart from each other, and a first gate electrode on the first semiconductor patterns. The first gate electrode comprises a first work function metal pattern on a top surface, a bottom surface, and sidewalls of respective ones of the first semiconductor patterns, a barrier pattern on the first work function metal pattern, and a first electrode pattern on the barrier pattern.

The barrier pattern and the first electrode pattern are spaced apart from the first part.

There is provided a master glass having a structure capable of preventing damage caused by static electricity. The master glass is a substrate on which a deposition process is experimentally performed by being experimentally loaded loading the master glass into a deposition apparatus before starting the deposition process of the substrate for electronic devices. In one embodiment, a master glass includes first conductive patterns and a second conductive pattern. The first conductive patterns are formed to correspond to a deposition pattern required in a substrate for electronic devices. The second conductive pattern electrically connects all the first conductive patterns to one another.
