Title: Semiconductor memory device and method of fabricating the same

Abstract: Provided is a semiconductor device and method of fabricating the semiconductor memory device. The semiconductor device may be formed by forming a first welding groove along outside edges of one case of a pair of upper and lower cases, forming a first welding protrusion along outside edges of the other case, the first welding protrusion being formed to correspond to the first welding groove and having a volume larger than a volume of the first welding groove. The method may further include inserting the first welding protrusion into the first welding groove to enclose a memory module in an inner accommodating space of the upper and lower cases, melting the first welding protrusion so that a first portion of the first welding protrusion fills the first welding groove and a second portion of the first welding protrusion fills a space between welding portions of the upper case and the lower case, and solidifying the first and second portions of the first welding protrusion.
