    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: The present invention relates to a highly integrated SOI semiconductor device and a method for fabricating the SOI semiconductor device by reducing a distance between diodes or well resistors without any reduction in insulating characteristics. The device includes a first conductivity type semiconductor substrate and a surface silicon layer formed by inserting an insulating layer on the semiconductor substrate. A trench is formed by etching a predetermined portion of surface silicon layer, insulating layer and substrate to expose a part of the semiconductor substrate to be used for an element separating region, and a STI is formed in the trench. A transistor is constructed on the surface silicon layer surrounded by the insulating layer and STI with a gate electrode being positioned at the center thereof and with source/drain region being formed in the surface silicon layer of both edges of the gate electrode for enabling its bottom part to be in contact with the insulating layer. A first groove is formed between the STI at one side of the transistor by etching the surface silicon layer and insulating layer to expose a predetermined portion of an active region of a second conductivity type well in the semiconductor substrate. A second groove is formed between the STI at one side of the first groove by etching the surface silicon layer and insulating layer to expose a predetermined portion of the active region of the semiconductor substrate. A first diode diffusion region of a first conductivity type is formed in a second conductivity type well under the first groove, and a second diode diffusion region of a second conductivity type is formed in the semiconductor substrate under the second groove.

    摘要: A cell structure of a non-volatile memory device, which uses a nitride layer as a floating gate spacer, includes a gate stack and a floating gate transistor formed over a semiconductor substrate. The gate stack includes a first portion of a floating gate, a control gate formed over the first portion of the floating gate, and a non-nitride spacer adjacent to sidewalls of the first portion of floating gate. The floating gate transistor includes a second portion of the floating gate, which substantially overlaps a source and/or drain formed in the substrate. The application of ultraviolet rays to the non-nitride spacer of a programmed cell can causes the second portion of the floating gate to discharge, thereby easily erasing the programmed cell.
