    摘要: A reticle (10) permits the alignment of three orthogonal axes (X, Y and Z) that intersect at a common target point (30). Thin, straight filaments (12, 14 and 16) are supported on a frame (20). The filaments are each contained in a different orthogonal plane (S.sub.xy, S.sub.xz, and S.sub.yz) and each filament intersects two of the three orthogonal axes. The filaments, as viewed, along the frame axis (22), give the appearance of a triange (24) with a V (17) extending from each triangle vertex (25, 26, and 27). When axial alignment is achieved, the filament portions adjacent to a triangle vertex are seen (along the axis of interest) as a right-angle cross, whereas these filament portions are seen to intersect at an oblique angle when axial misalignment occurs. The reticle is open in the region near the target point leaving ample space for alignment aids such as a pentaprism 54 or a cube mirror 41.

    摘要: A wafer handling wand allows the efficient loading and unloading of semiconductor wafers to and from a CMP apparatus. The wand includes identical work piece gripping, alignment, and loading/unloading mechanisms on the top and bottom sides. A processed wafer can be unloaded from the apparatus onto one side of the wand and an unprocessed wafer can be loaded into the apparatus from the second side. The gripping mechanism includes a support area and a spaced apart moveable gripping finger. Wafer loading is facilitated by a cam attached to the support area that rotates when the cam contacts the apparatus. Upon rotation, the cam provides a surface for directing the work piece into the apparatus. The surface of the cam also includes an alignment aid that can be brought into contact with a reference surface on the apparatus to insure proper alignment between the wand and the apparatus.

    摘要: A method of fabricating microelectronic structure using at least two material removal steps, such as for in a poly open polish process, is disclosed. In one embodiment, the first removal step may be chemical mechanical polishing (CMP) step utilizing a slurry with high selectivity to an interlevel dielectric layer used relative to an etch stop layer abutting a transistor gate. This allows the first CMP step to stop after contacting the etch stop layer, which results in substantially uniform “within die”, “within wafer”, and “wafer to wafer” topography. The removal step may expose a temporary component, such as a polysilicon gate within the transistor gate structure. Once the polysilicon gate is exposed other processes may be employed to produce a transistor gate having desired properties.
