摘要： A semiconductor device having multi-gate insulating layers and methods of fabricating the same are provided. The semiconductor device includes an isolation region disposed at a predetermined region of a semiconductor substrate. The isolation region defines at least one first active region and at least one second active region. The first active region is covered with a first gate insulating layer, and the second active region is covered with a second gate insulating layer which is thinner than the first gate insulating layer. Preferably, the top surface of the first gate insulating layer has the same height as the that of the second gate insulating layer. The isolation region is filled with an isolation layer which preferably covers the entire sidewalls of the first and second gate insulating layers. A typical method includes the step of selectively forming a first gate insulating layer at a predetermined region of a semiconductor substrate. A second gate insulating layer which is thinner than the first insulating layer is selectively formed at the surface of the semiconductor substrate adjacent to the first gate insulating layer. Preferably, the bottom surface of the first gate insulating layer is lower than that of the second gate insulating layer. The first and second gate insulating layers are covered with a conductive layer. The conductive layer, the first and second gate insulating layers, and the substrate are etched to form an isolation region, for example, a trench region, defining a first active region under the first gate insulating layer and a second active region under the second gate insulating. An isolation layer is formed in the trench region. The isolation layer preferably covers the entire sidewalls of the first and second gate insulating layers.

摘要： A method for forming a conductive line uses a fluorine doped oxide layer as an insulating layer between conductive lines. The method comprises the steps of: (a) forming a fluorine doped oxide layer on a semiconductor substrate on which a lower structure is formed; (b) etching the oxide layer of the region where a conductive line is to be formed, thereby forming a trench; (c) forming an insulating layer on the overall surface of the resultant substrate; depositing conductive material on the resultant substrate; and (e) etching back the conductive material so that the conductive material is left on the trench only, thereby forming a conductive line. In this method, the conductive line is formed of aluminum-containing material and the insulating layer is formed of silicon dioxide. In the present invention, the insulating layer is interposed between the fluorine doped oxide layer and the aluminum-containing conductive line and thus the conductive line is free from corrosion.

摘要： A deposition rate of a dielectric material is varied with the electrical polarity of an underlying layer to obtain excellent deposition and planarization characteristics. A conductive layer and the underlying dielectric are surface-treated to have different electrical polarities so that the dielectric is formed by using the difference of deposition rates of the dielectric material between that on the conductive layer and that on the underlying dielectric. A CVD apparatus having a DC power source connected between a susceptor and a gas injection portion thereof is provided. The deposition and planarization can be performed at low temperatures and are simplified in process.
