摘要： Trench isolation methods for integrated circuits may reduce irregularities in the formation of an isolation layer through use of a high selectivity chemical-mechanical polishing (CMP) operation. In particular, a substrate surface is etched to form a trench. An insulation layer is then formed on the substrate surface and in the trench. The insulation layer is chemical-mechanical polished using a slurry that includes a CeO2 group abrasive to form an isolation layer in the trench. The CMP selectivity ratio of a slurry that includes a CeO2 group abrasive may be sufficient to allow the substrate surface to be used as a CMP stop. As a result, a more consistent level of polishing may be maintained over the substrate surface, which may result in a more uniform thickness in the isolation layer.

摘要： A method of forming a shallow trench isolation layer in a semiconductor device is provided, wherein a first trench and a second trench are formed in an area selected from a semiconductor substrate and a sidewall oxide layer, an anti-oxidation liner, and a mask layer are formed on the semiconductor substrate including the inner surfaces of the first and second trenches, in the same order. Using photoresist lithography, the mask layer and the anti-oxidation layer are etched in the second trench. An isolation layer is formed in the first and second trenches by depositing and then chemically and mechanically polishing the dielectric material and the layers underneath until the semiconductor substrate surface is exposed. The first trench provides isolation between N-FETs, an N-FET and a P-FET, an N-FET and other circuit devices, a P-FET and other circuit devices, and other circuit devices and the second trench provides isolation between P-FETs.

摘要： Trench isolation methods for integrated circuit substrates may be simplified by eliminating the steps of forming a silicon nitride layer, etching the silicon nitride layer and removing the silicon nitride layer. In particular, a silicon nitride-free mask pattern, such as a photoresist mask pattern, may be formed on a silicon nitride-free integrated circuit substrate. The silicon nitride-free integrated circuit substrate is etched through the silicon nitride-free mask pattern to form a trench in the substrate. An insulating layer is formed in the trench and is chemical-mechanical polished to form a trench isolating layer. By eliminating the silicon nitride layer, simplified processing and improved performance may be obtained.

摘要： Provided is a double gate field effect transistor and a method of manufacturing the same. The method of manufacturing the double gate field effect transistor comprises forming as many fins as required by etching a silicon substrate, masking the resultant product by an insulating material such as silicon nitride, forming trench regions for device isolation and STI film by using the silicon nitride mask, forming gate oxide films on both faces of the fins after removing the hard mask, and forming a gate line. As such, unnecessary channel formation under the silicon oxide film, when a voltage higher than a threshold voltage is applied to the substrate, is prevented by forming a thick silicon oxide film on the substrate on which no protruding fins are formed.

摘要： A trench isolation structure which prevents a hump phenomenon and an inverse narrow width effect of transistors by rounding the top edges of a trench and increasing the amount of oxidation at the top edges of a trench, a semiconductor device having the trench isolation structure, and a trench isolation method are provided. In this trench isolation method, a trench is formed in non-active regions of a semiconductor substrate. An inner wall oxide film having a thickness of 10 to 150 Å is formed on the inner wall of the trench. A liner is formed on the surface of the inner wall oxide film. The trench is filled with a dielectric film. Part of the liner is etched so that the top ends of the silicon nitride liner are recessed from the surface of the semiconductor substrate.
