A stent inserting device is used in inserting a self-expandable stent with leading and trailing ends into a tubular organ of a living body. The stent inserting device includes a grip body, an external tube attached to a front end of the grip body, a push member movably inserted into the external tube from a rear end of the grip body, and a tubular cap for removably receiving the stent in a compressed state. The tubular cap has a front end operatively connected to the push member and a rear end slidably fitted to a front end of the external tube. The stent inserting device is designed to hold the stent within the tubular cap in such a manner that the stent is first expanded at the trailing end and then gradually expanded toward the leading end when the tubular cap is pushed away from the external tube.

A memory device includes a first active region on a substrate and first and second source/drain regions on the substrate abutting respective first and second sidewalls of the first active region. A first gate structure is disposed on the first active region between the first and second source/drain regions. A second active region is disposed on the first gate structure between and abutting the first and second source/drain regions. A second gate structure is disposed on the second active region overlying the first gate structure.

In a method of forming a pattern, a sacrificial layer pattern and a stop layer pattern for preventing or reducing an epitaxial growth may be formed on a substrate. The sacrificial layer pattern may have a first hole therethrough, and the first hole partially exposes a top surface of the substrate. At least one active pattern may be formed on a bottom and a sidewall of the first hole by performing a selective epitaxial growth process on the top surface of the substrate and a sidewall of the sacrificial layer pattern. The sacrificial layer pattern and the stop layer pattern for preventing or reducing the epitaxial growth may be removed from the substrate. The at least one active pattern formed by the above method may have a finer size and an improved shaped compared to a conventional active pattern formed by directly patterning layers using a photoresist pattern. Damages in a photolithography process may be prevented or reduced from being generated.

A semiconductor device having a field effect transistor and a method of fabricating the same. In-situ doped epitaxial patterns are respectively formed at both sidewalls of a protruded channel pattern from a substrate by performing an in-situ doped epitaxial growth process. The in-situ doped epitaxial pattern has a conformal impurity concentration throughout. Accordingly, source/drain regions with a conformal impurity concentration are connected throughout a channel width of a channel region including both sidewalls of a protruded channel pattern. As a result, it is possible to maximize a driving current of the filed effect transistor, and an on-off characteristic can be highly stabilized.

Disclosed is a stent for the coil embolization of a cerebral aneurysm. The stent according to one embodiment of the present invention is shaped as a cylinder formed of a mesh-structured metal thin wire to enable a coil to fill the inside of said cerebral aneurysm through the mesh of the stent. And the stent has such a shape as the maximum diameter of the center portion of the stent is larger than the maximum diameter of each of both end portions of the stent. For example, the stent may have a fusiform shape in which the center portion protrudes further than the end portions.
