摘要:
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.

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.

A method of forming damascene wiring without dishing and erosion employs a dummy layer to slow or delay polishing in selected regions and thereby prevent dishing and erosion of the damascene wiring. The dummy layer is above wide damascene regions and areas containing closely packed damascene regions. Therefore, non-uniform sheet resistance of the damascene metal wiring and electro-migration due to an increase in the local current density of the metal wiring can be prevented.

A method for efficiently removing by-products produced in dry-etching a fabricated structure of a semiconductor device, particularly, a polycide structure. The method includes the steps of sequentially forming a polysilicon layer and a refractory metal silicide layer to overlie previously fabricated structures on a semiconductor substrate, dry-etching the polysilicon layer and the refractory metal silicide layer to form a patterned polysilicon layer and a patterned refractory metal silicide layer, and thermal treating the resultant structure to remove at least one kind of by-product produced in the dry-etching step at a temperature higher than the boiling point of any by-product.

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.

An SOI MOSFET having a body contact for preventing the floating body effect is provided. The body contact is a trench perforating a body and a buried oxide layer to a semiconductor substrate. The trench is filled with a conductive material to electrically connect the body to the semiconductor substrate. Impurity ions are implanted into a predetermined region of the semiconductor substrate in contact with the lower portion of the body contact to form an ohmic contact. In the SOI MOSFET, an additional metal interconnection line is not needed to supply power to the body. Also, malfunction of a circuit due to stray capacitance of a contact can be prevented.
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.

摘要:
An integrated circuit device is fabricated by forming at least one isolation region in an area of a semiconductor substrate, such as a monolithic semiconductor substrate or a silicon on insulator (SOI) substrate. The at least one isolation region defines at least one active region. A plurality of dummy conductive regions is distributed in the area of the semiconductor substrate, with the dummy conductive regions being constrained to overlie the at least one isolation region. The dummy conductive regions may be formed from a conductive layer that is also used to form, for example, a gate electrode, a capacitor electrode or a wiring pattern. The dummy conductive regions may be formed on an insulation layer, e.g., a gate insulation layer or an interlayer dielectric layer. Preferably, the dummy conductive regions are noncontiguous. In one embodiment, a lattice-shaped isolation region is formed including an array of node regions linked by interconnecting regions and defining an array of dummy active regions. The plurality of dummy conductive regions are formed on the node regions of the lattice-shaped isolation region. In another embodiment, an array of isolation regions is formed, defining a lattice-shaped dummy active region. An array of dummy conductive regions is formed on the array of isolation regions. Related integrated circuit devices are also described.
