Abstract:
Methods of filling high aspect ratio trenches in semiconductor layers are provided. The methods utilize HDP-CVD processes to fill trenches with trench filling material. In the methods, the gas flow and RF bias are selected to provide a high etch to deposition ratio, while the trenches are partially filled. The gas flow and RF bias are then selected to provide a low etch to deposition ratio while the trenches are completely filled. It is emphasized that this abstract is provided to comply with the rules requiring an abstract which will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure. It is submitted with the understanding that is will not be used to interpret or limit the scope or meaning of the claims.
Abstract:
An ELID honing device includes a honing tool 10 positioned above a workpiece 1 having a hollow cylindrical inner surface, and vertically movable and rotationally drivable about a vertical rotation axis while being rockably suspended from an upper end, and a honing guide 20 positioned in proximity to an upper portion of the workpiece to guide the honing tool to the hollow cylindrical inner surface. The honing tool 10 has a fixed guide 12 having a predetermined radius R from the rotation axis to its outer peripheral surface, and honing stones 14a and 14b having outer peripheral surfaces movable in parallel from a diameter-increased position outside the radius R to a diameter-reduced position inside the radius R and capable of being electrolytically dressed. Further, the honing guide 20 has a hollow cylindrical ELID electrode 22 having an inner surface 22a for guiding an outer peripheral surface of the fixed guide of the honing tool and capable of being subjected to a negative voltage.
