Abstract: This invention relates to a method of polishing magnetic oxides or bubble crystal surfaces to a featureless and strain-free condition. The method comprises pre-polishing or lapping with a suspension of polycrystalline garnets to a conchoidal condition followed by final polishing with a zirconium oxide slurry under polishing pressure between 2 and 40 psi.

Abstract: The method comprises the chemical-mechanical polishing of titanium carbide containing surfaces to a high degree of perfection. The titanium carbide containing surfaces are continuously wetted with a water slurry containing a soft abrasive material. The continuously wiping of the titanium carbide surface is accomplished with a firm surface (16) using pressure while maintaining a relative movement between the titanium carbide containing surface and the firm surface (16) to remove the water reacted titanium carbide product from the high points of the titanium carbide containing surface. This method is continued until a high degree of perfection of the surface is accomplished. The slurry is typically composed of colloidal silicon dioxide dispersed in water. The titanium carbide surface can also include aluminum oxide as a constituent. Where aluminum oxide is present it is preferred to have about 60 to 80% aluminum oxide and 40 to 20% titanium carbide by weight in the surface structure.

Abstract: Improved Wafer Shape and Method of Making Same A semiconductor wafer shape which when subjected to a simultaneous polishing of both wafer surfaces produces a wafer of superior flatness and surface finish, the said wafer having a diametral cross-sectional shape like that of a "dogbone" wherein the wafer is thinner in its medial region than it is in the peripheral region and has rounded edges, this shape resulting from a chemical thinning operation.

Abstract: A method is disclosed for producing coplanar metal/insulator films on a substrate according to a chem-mech polishing technique. In one example, a substrate having a patterned insulating layer of dielectric material thereon, is coated with a layer of metal. The substrate is then placed in a parallel polisher and the metal is removed elsewhere except in the holes where it is left intact. This is made possible through the use of an improved selective slurry which removes the metal much faster than the dielectric material. The insulating layer may then be used as an automatic etch stop barrier. In a second example a substrate having a paterned metallic layer is coated with an insulating layer and then subjected to chem-mech polishing. The structure is coplanarized by the chem-mech removal of the insulating material from the high points of the structure at a faster rate than from the lower points. Optional etch stop layers also may be used.

Abstract: A chemical-mechanical (chem-mech) method for removing SiO₂ protuberances at the surface of a silicon chip, such protuberances including "bird heads". A thin etch stop layer of Si₃N₄ (29) is deposited onto the wafer surface, which is then chem-mech polished with a SiO₂ water based slurry. The Si₃N₄ acts as a polishing or etch stop barrier layer only on the planar portions of the wafer surface. The portions of the Si₃N₄ layer located on the top and at the sidewalls of the "bird' heads" and the underlying SiO₂ protuberances are removed to provide a substantially planar integrated structure.

Abstract: PROCESS AND APPARATUS FOR FREE POLISHING Opposite faces of a workpiece, such as a semiconductor wafer, are simultaneously free polished by contacting the faces with a pair of rotating polishing pads to which are fed a polishing slurry of an abrasive material. A pattern of perforations is provided in the surface of at least one of the pads such that the area of pad in contact with the opposite faces of the workpiece is different. FI 9-78-031
