    摘要: Systems and methods for aligning wafers. A first method provides for placing a wafer carrier comprising a mis-aligned wafer into an acceptance port. A wafer alignment fixture is moved relative to the wafer carrier and perpendicular to the plane of the mis-aligned wafer. The wafer alignment fixture comprises a spring action member. A force from said spring action member is exerted upon the mis-aligned wafer to achieve a desirable alignment of the mis-aligned wafer within the wafer carrier.

    摘要: A method is described for thin film processing using a selected CMP slurry with a silicon dioxide stop layer. The slurry includes an abrasive, preferably alumina, a corrosion inhibitor, preferably benzotriazole (BTA), and an oxidizer preferably hydrogen peroxide. The method is particularly useful for fabricating thin film heads where alumina is used as the dielectric. The method can be used to planarize metal structures surrounded by alumina in magnetic heads. The alumina refill is deposited to the final target height which is slightly below the height of the metal. A thin silicon dioxide stop layer is deposited over the alumina. The CMP is executed using the selected slurry to planarize the wafer down to the stop layer. Preferably only a negligible amount of the stop layer remains and the height of the metal structure is essentially the same as the deposited height of the refilled alumina.

    摘要: A chemical-mechanical nanogrinding process achieves near-zero pole tip recession (PTR) to minimize magnetic space loss of the head transducer to media spacing loss, alumina recession/trailing edge profile variation, and smooth surface finish with minimal smearing across multi-layers of thin films and the hard substrate to meet the requirements of high areal density head. With a fine lapping plate with a fixed-abrasive nanogrinding process, PTR can be improved to a mean of about 1.0 nm.

A preferred chemical mechanical polishing (CMP) method includes a CMP polishing compound including alumina abrasive particulates, 1H-Benzotriazole (BTA), and hydrogen peroxide (H2O2). A cleaning solution for CoFeNi structures in alumina fill of the present invention preferably includes 4-Methyl-1H-Benzotriazole in a concentration range of from 1% to 5%, 5-Methyl-1H-Benzotriazole in a concentration range of from 1% to 5%, hydrogenated 4-Methyl-1H-Benzotriazole in a concentration range of from 1% to 5%, hydrogenated 5-Methyl-1H-Benzotriazole in a concentration range of from 1% to 5%, sodium octanoate in a concentration range of from 5% to 10%, and water in a concentration range of from 65% to 95%. The cleaning solution is typically used with DI water to create an applied solution having a range of from 0.1% to 10% by volume of the cleaning solution.

    摘要: During planarization of wafers, the thickness of a layer of a wafer is measured at a number of locations, after the wafer has been planarized by chemical mechanical polishing. The thickness measurements are used to automatically determine, from a center to edge profile model to which the measurements are fit, a parameter that controls chemical mechanical polishing, called “backside pressure.” Backside pressure is determined in some embodiments by a logic test based on the center-to-edge profile model, coefficient of determination R-square of the model, and current value of backside pressure. Note that a “backside pressure” set point is adjusted only if the fit of the measurements to the model is good, e.g. as indicated by R-square being greater than a predetermined limit. Next, the backside pressure that has been determined from the model is used in planarizing a subsequent wafer.
