摘要： A method of fabricating shallow trench isolations (STI) which forms a substrate with a patterned first oxide layer and a patterned silicon nitride layer thereon, so that active regions are defined with openings formed between the active regions. The openings are then over etched to form trenches for fabricating the STI, followed by forming a second oxide layer that conforms to a profile of the trenches. A third oxide layer is globally formed over the second oxide layer, sidewalls of the first oxide layer, and the silicon nitride layer. A thermal process is performed to densify a portion of the third oxide layer, so that a top portion of the third oxide layer is harder than a lower portion of the third oxide layer. The excessive portion of the third oxide layer above the silicon nitride layer is removed by performing chemical mechanical polishing, which planarizes a top surface of the third oxide layer in order to complete the manufacture of the STI.

摘要： A method of stabilizing an anti-reflection coating (ARC) layer is disclosed. The method provides a substrate with a dielectric layer, a conductive layer, and the ARC layer formed thereon. The ARC layer is treated in an alloy treatment step prior to forming a photoresist layer over the ARC layer, so that the specificity of the ARC layer is stabilized to allow accurate transfer of a desired pattern. A photomask with the desired pattern is provided, while a photolithographic process is then performed to transfer the pattern onto the wafer.

摘要： A method of stabilizing an anti-reflection coating (ARC) layer is disclosed. The method provides a substrate with a dielectric layer, a conductive layer, and the ARC layer formed thereon. The ARC layer is treated in an ultraviolet (UV) curing step prior to forming a photoresist layer over the ARC layer, so that the specificity of the ARC layer is stabilized to allow an accurate pattern is replicated in the photoresist layer. A photomask with the desired pattern is provided, while a photolithographic process is then performed to transfer the pattern onto the wafer.

摘要： A method of fabricating an electrostatic protection device, comprises a semiconductor substrate which includes a first type well, a second type well, and a field oxide layer in between. A first gate, a first spacer, and a first source/drain are formed in the first type well. The second type has a second gate, a second spacer, and the second source/drain formed therein. In addition, an oxide layer is distributed on the first gate, the second gate, a part of the first source/drain, and a part of the second source/drain. A silicide layer is formed on the uncovered first source/drain and the uncovered second source/drain. Therefore, the silicide layer and the gate oxide layer are spaced apart.

摘要： A method is provided for fabricating an EEPROM (EEPROM (electrically erasable and programmable read-only memory) device, which can help improve the quality of the tunneling oxide layer in the EEPROM device for reliable operation of the EEPROM device. This method is characterized in that the portion of the tungsten silicide (WSi) layer that is directly laid above the tunneling oxide layer is removed, while still allowing all the other part of the tungsten silicide layer to remain unaltered. As a result, in the subsequent heat-treatment process, the degradation in the quality of the tunneling oxide layer that occurs in the prior art due to the forming of a trapping center therein can be prevented. The tunneling oxide layer is thus more assured in quality, allowing the resultant EEPROM to operate reliably with high performance.

摘要： A multi-level conductive interconnection for an integrated circuit with an antifuse device is formed, in and on a silicon substrate, wherein there are large contact pad areas at the periphery of the interconnection. The antifuse device is formed from a thin dielectric between a first and second conductor and is connected to the integrated circuit, and is also connected to a ground reference through a silicon junction in the substrate. The large contact pad area is formed with a layer of metal, and is connected to the integrated circuit through the antifuse device, wherein the antifuse device electrically isolates the contact pad and the integrated circuit to prevent charge build-up during subsequent processing. There is further processing in a plasma environment that would normally produce electrical charge build-up at the gate oxide of the integrated circuit, but wherein the antifuse device prevents charge build-up. A voltage is applied to the antifuse device to create a low impedance element, and formation of the integrated circuit is completed.
