A semiconductor device including a transistor and a method of forming thereof are provided. The semiconductor device comprises a metal gate electrode. A lower portion of the metal gate electrode fills a channel trench formed at a predetermined region of a substrate, and an upper portion of the metal gate electrode protrudes on the substrate. A gate insulating layer is interposed between inner sidewalls and a bottom surface of the channel trench, and the metal gate electrode. Source/drain regions are formed at the substrate in both sides of the metal gate electrode.

A semiconductor memory device includes a substrate having active regions extending in a first direction and separated therealong by a device isolation layer, and conductive word lines extending on the substrate in a second direction intersecting the first direction. Ones of the word lines extending between the active regions define isolation gate lines, which are insulated from the active regions by the device isolation layer. Edges of the active regions adjacent the isolation gate lines respectively include first and second corners that are spaced apart from an adjacent one of the isolation gate lines by substantially equal distances. Related fabrication methods are also discussed.

A method of fabricating a package-on-package (POP) package is disclosed. The method includes preparing a first semiconductor package including a first substrate having external contact electrodes and a first semiconductor chip mounted on the first substrate, and preparing a second semiconductor package including a second substrate having external contact electrodes and a second semiconductor chip mounted on the second substrate. The method further includes forming lead lines in the second semiconductor package, the lead lines being electrically connected to the external contact electrodes of the second substrate, and stacking the second semiconductor package on the first semiconductor package and electrically connecting the external contact electrodes of the first substrate to the external contact electrodes of the second substrate using the lead lines.

In a substrate processing apparatus using a neutralized beam and a method thereof, the substrate processing apparatus includes: an ion source for emitting an ion beam at an emitting angle; reflectors at which the ion beam emitted by the ion source is incident and subject to 2n collisions (where n is a positive integer) in first and second opposite directions to neutralize the ion beam as a neutralized beam and to restore a direction of propagation of the neutralized beam to the emitting angle of the ion beam; and a substrate at which the neutralized beam generated by the reflectors is incident on to perform a process. Accordingly, an incident angle of the resultant neutralized beam is perpendicular to a substrate, while the direction of propagation of the originating ion source and the surface of the substrate are maintained to be perpendicular to each other.
