Abstract: Disclosed herein is a battery pack constructed such that a battery case, in which an electrode assembly is mounted, is made of a laminate sheet having high strength, side sealing parts of the battery case are formed in a specific shape, and a protection circuit module (PCM) is located in the inner space of at least one of the side sealing parts. The side sealing parts in themselves are used as a structure to decide the external shape of the battery pack, and, at the same time, are used as spaces for mounting the PCM therein. Consequently, it is possible to construct the battery pack without using additional pack sheathing members, to simplify the assembly process of the battery pack, and to manufacture the battery pack in a thinner and more compact structure with the reduced manufacturing costs. Furthermore, the PCM is located at either side of the battery cell while the PCM is spaced apart from electrode terminals.

Abstract: A first conductive impurity ion is implanted into a semiconductor substrate to form a well area on which a gate electrode is formed. A first non-conductive impurity is implanted into the well area on both sides of the gate electrode to control a substrate defect therein and to form a first precipitate area to a first depth. A second conductive impurity ion is implanted into the well area on both sides of the gate electrode, so that a source/drain area is formed to a second depth being relatively shallower than the first depth. A second non-conductive impurity is implanted into the source/drain area so as to control a substrate defect therein and to form a second precipitate area. As a result, substrate defects such as dislocation, extended defect, and stacking fault are isolated from a P-N junction area, thereby forming a stable P-N junction.
