A silicon-on-insulator (SOD integrated circuit and a method of fabricating the SOI integrated circuit are provided. At least one isolated transistor active region and a body line are formed on an SOI substrate. The transistor active region and the body line are surrounded by an isolation layer which is in contact with a buried insulating layer of the SOI substrate. A portion of the sidewall of the transistor active region is extended to the body line. Thus, the transistor active region is electrically connected to the body line through a body extension. The body extension is covered with a body insulating layer. An insulated gate pattern is formed over the transistor active region, and one end of the gate pattern is overlapped with the body insulating layer.
摘要:
The present invention relates to an SOI semiconductor device and a method for fabricating an SOI semiconductor device, in which the portions formed with silicide layers are laterally restricted by spacers to a predetermined range in the diffusion regions to be used for diodes or well resistors. In this manner, it is possible to fix the length of distance between the sides of a silicide layer and a diffusion region, greater than that available in the prior art techniques, thereby minimizing power leakage at the sides of the diffusion regions. In the SOI semiconductor device thus constructed, the diffusion regions to be used for diodes (or well resistors) are constructed with spacers in a double junction structure of different density of impurity layers (for instance, a P− or N− layer respectively surrounds a P+ or N+ layer), in other words, only onto a high density of impurity layer, the P+ or N+ layer, or in a single junction structure in which the spacers restrict a range of space for forming the silicide layer in the diffusion region.

An SRAM cell that may reduce or eliminate floating body effect when using a SOI and a method for fabricating the same are provided. A floating body of an access transistor of the SRAM is connected to a source region of a driver transistor, for example, through a body extension region extending from an active region. A silicide layer may be formed or a ground line contact may be over-etched to form a conductive contact plug that may provide a current path between the body exterior regions and the source region of the driver transistor.
摘要:
A method of forming a dual damascene interconnection employs a low-k dielectric organic polymer as an insulating layer. With only one hard mask layer, ashing damage to the insulating layer is prevented using a hard mask layer and an etch-stop layer that are different in etch rate from that of a self-aligned spacer. Further, it is possible to form a via hole that is smaller than the resolution limit of the photolithographic process. As a result, the process is simplified and a photoresist tail phenomenon does not occur.

In a method of manufacturing a semiconductor device to improve structural stability of a semiconductor device in a silicidation process, a substrate is provided to have an active region defined by an isolation layer. An etching mask is formed on the active region and the isolation layer to have a silicidation prevention pattern that at least partially exposes the active region. A gate structure is formed on the exposed active region. A gate spacer is formed on a sidewall of the gate structure positioned on the silicidation prevention pattern. Source/drain regions are formed on the active region using the gate spacer as a mask to thereby form the semiconductor device. Since voids may not be generated in a transistor of the semiconductor device or intrusion of the transistor may be prevented in the silicidation process, the semiconductor device including the transistor may have improved reliability and electrical characteristics.
