摘要： A process for stripping thin layers of oxide such as sacrificial pad oxide employs etching chemistry that widens cracks to remove shallow cracks and limit the widening of deep cracks, thereby producing a final oxide surface on thick layers of oxide that is less rough than prior art methods and enabling the fabrication of oxide-filled trenches that have geometries and/or surface smoothness that were previously impossible.

摘要： A blocking layer is formed on a hard mask having an initial thickness. Lines are fabricated by patterning the blocking layer and the hard mask to provide a line segment, the line segment having a first dimension measured across the line segment; reacting a surface layer of the line segment to form a layer of a reaction product on a remaining portion of the line segment; and removing the reaction product without attacking the remaining portion of the line segment and without attacking the blocking layer and the substrate to form the line segment with a second dimension across the line segment that is smaller than the first dimension. The blocking layer prevents the formation of reaction product on the hard mask so that the initial thickness of the hard mask is maintained. The blocking layer can also serve as an ARC layer for photoresist patterning so that the use of an additional film layer is not required.

摘要： In supersonic molecular beam etching, the reactivity of the etchant gas and substrate surface is improved by creating etchant gas molecules with high internal energies through chemical reactions of precursor molecules, forming clusters of etchant gas molecules in a reaction chamber, expanding the etchant gas molecules and clusters of etchant gas molecules through a nozzle into a vacuum, and directing the molecules and clusters of molecules onto a substrate. Translational energy of the molecules and clusters of molecules can be improved by seeding with inert gas molecules. The process provides improved controllability, surface purity, etch selectivity and anisotropy. Etchant molecules may also be expanded directly (without reaction in a chamber) to produce clusters whose translational energy can be increased through expansion with a seeding gas.

摘要： A reactor is provided for heating a workpiece in a sealed environment. The reactor has a chamber with a gas inlet port, a gas outlet port, and at least one tube for receiving a heat source. The tube passes from outside the chamber into the inside of the chamber without breaking the chamber seal. Alternately, the tubes may be used for treating the workpiece with light, in combination with or instead of heat treatment.

摘要： An oxide etch process is described which may be used for emitter and base preparation in bipolar SiGe devices. The low temperature process employed produces electrical insulation between the emitter and base by a COR etch which preserves insulating TEOS glass. The insulating TEOS glass provides reduced capacitance and helps to achieve high speed. An apparatus is also described for practicing the disclosed process.

摘要： Hydrogen fluoride undercut of oxide layers may be reduced by using a low pressure mixture of gaseous hydrogen fluoride and gaseous ammonia mixture. Organic photoresists can be used as a masking material when using the gaseous hydrogen fluoride/ammonia mixture without resulting in an enhanced reaction rate. In addition, because of the reaction conditions, the dimensions in the oxide layer being etched can be specifically sized smaller than openings made in the overcoating masking material.

摘要： A method of patterning a layer on sidewalls of a trench in a substrate for integrated circuits includes the steps of forming an insulator layer on sidewalls of a trench in a substrate with a horizontal top surface above the sidewalls, recessing a masking material such as an organic photoresist in the trench below the top surface of the substrate such that a portion of the insulator layer on the sidewalls of the substrate is exposed, and etching the insulator layer with a gaseous hydrogen flouride-ammonia mixture. The masking material and the substrate are composed of a different material than the insulator layer.
