Abstract: A method for depositing dielectric material into gaps between wiring lines in the formation of a semiconductor device includes the formation of a cap layer and the formation of gaps into which high density plasma chemical vapor deposition (HDPCVD) dielectric material is deposited. First and second antireflective coatings may be formed on the wiring line layer, the first and second antireflective coatings being made from different materials. Both antireflective coatings and the wiring line layer are etched through to form wiring lines separated by gaps. The gaps between wiring lines may be filled using high density plasma chemical vapor deposition.

Abstract: A method of chemical-mechanical polishing for forming a shallow trench isolation is disclosed. A substrate having a number of active regions, including a number of relatively large active regions and a number of relative small active regions, is provided. The method comprises the following steps. A silicon nitride layer on the substrate is formed. A number of shallow trenches are formed between the active regions one or more of which may constitute an alignment mark. An oxide layer is formed over the substrate, so that the shallow trenches are filled with the oxide layer. A partial reverse active mask is formed on the oxide layer. The partial reverse active mask exposes a portion of the oxide layer over the large active area and over the alignment mark. The oxide layer of each large active region and the alignment mark is removed. The partial reverse active mask is removed. The oxide layer is planarized.

Abstract: The present invention contemplates a method and apparatus to generate a laser probe beam free of speckles. The present invention employs a holographic phase plate inserted in a laser beam path to modulate the relative phase across the beam. The holographic phase plate is designed to optimize the phase modulation across the beam while to minimize the degradation of the beam quality. The modulated laser beam has only a small and confined divergent angle and can then be refocused or collimated into a narrow and near collimated probe beam. The present invention further rotates the holographic phase plate to randomize the speckles in a time sequence. As a result, the probe beam preserves substantially the beam quality of a laser and produces substantially no speckles on image of its, intersection with a surface or material.

Abstract: The optical tracking device of the present invention is contemplated to obtain a large tracking range in an open loop configuration. The tracking device projects and scans two probe beams across a symmetric reference landmark that has at least two symmetric lines or axes. The two probe beams scan repeatedly and alternatively along two directions of which each is perpendicular to a symmetric line of the reference mark. For each scan, a substantially symmetric profile is generated in the scattered light as the beam scans across the boundary on each side of the symmetric reference. This symmetric profile in the scattered light is detected and used to determine the position of the related symmetric line. The position detection of the symmetric line is independent from the object's movement along the direction of the symmetric line. The scattered-light signal from the two probe beams is separated by synchronized detection in the time domain.

The original active region pattern is expanded with a first parameter of line width to obtain a first pattern. By subtracting the first pattern, a second pattern is obtained. A dummy pattern which comprises an array of a plurality of elements is provided. By shifting the elements, a shifted dummy pattern is obtained. The second pattern and the shifted dummy pattern are combined, so that an overlapped region thereof is extracted as a combined dummy pattern. The combined dummy pattern is expanded with a second parameter of line width, so that a resultant dummy pattern is obtained. The resultant dummy pattern is added to the first pattern, so that the active region pattern with a shifted dummy pattern is obtained.
