Abstract: An integrated circuit chip having an anti-moisture-absorption film at the edge thereof and a method of forming the anti-moisture-absorption film are provided. In the integrated circuit chip which has predetermined devices inside and whose uppermost layer is covered with a passivation film, a trench is formed by etching interlayer dielectric films to a predetermined depth along the perimeter of the integrated circuit chip to be adjacent to the edge of the integrated circuit chip and an anti-moisture-absorption film is formed to fill the trench or is formed on the sidewall of the trench to a predetermined thickness, in order to prevent moisture from seeping into the edge of the integrated circuit chip. Moisture is effectively prevented from seeping into the edge of the chip by forming the anti-moisture-absorption film at the edge of the chip using the conventional processes of manufacturing the integrated circuit chip without an additional process.

Abstract: A method for fabricating a semiconductor device to reduce the contact resistance by enhancing the surface concentration of doped polysilicon in a semiconductor substrate divided into active and field regions, comprises the steps of forming a plurality of word lines each having a cap insulating layer with a predetermined interval between adjacent word lines on the substrate, forming source/drain impurity regions in the active regions adjacent to both sides of each of the word lines, forming insulating sidewalls on both sides of each of the word lines, forming capacitor node plugs and bit line contact plugs on the source/drain impurity regions, forming a plurality of bit lines in the direction perpendicular to the word lines with a predetermined interval between adjacent bit lines by forming bit line contact holes contacting the bit line contact plugs in a first insulating interlayer deposited on the substrate, forming storage electrode contact holes to expose the capacitor node plugs in a second insulating int

Abstract: A fuse area structure in a semiconductor device and a method of forming the same are provided. A ring-shaped guard ring which surrounds a fuse opening, for preventing moisture from seeping into the side surface of the exposed fuse opening, is included. The guard ring is integrally formed with a passivation film. In order to form the guard ring, a guard ring opening etching stop film is formed on a fuse line. A guard ring opening is formed using the etching stop film, and a contact hole is formed in a peripheral circuit. A conductive material layer for forming an upper interconnection layer is formed on the entire surface of a resultant structure on which the contact hole and the guard ring opening are formed. The conductive material layer formed on the guard ring opening is removed. The exposed etching stop film is removed. Finally, a passivation film is deposited on the entire surface of the resulting structure.

Abstract: A contact in a semiconductor memory device is formed on an active region of a cell array region, rather than on a sloped area between the cell array region and a core region. Preferably, an insulating layer on the active region is etched to form a hole therein and the contact formed through the hole. Preferably, the etching is performed using an etch solution having a high etch selectivity between the insulating layer and a top layer of the active region. Thus, the contact is evenly formed and the area of the cell array region is reduced, thereby enabling cells to be packed on a chip with high density.
