摘要:
A magnetic recording medium controllably textured by performing sputter etching or reactive ion etching either on the surface of a smooth substrate, which can be nickel-phosphorous/aluminum-magnesium (Al--Mg) substrate, or on the surface of a protective layer, such as a carbon overcoat. Both types of etching processes described above are carried out in a sputtering apparatus and have an etching mask of discrete hemi-spherical structures formed by the agglomeration of a low melting point metal or alloy such as indium or Pb--Sn, which has been deposited on a non-wetting surface such as the oxidized surface of NiP layer or the protective carbon overcoat prior to etching. The morphology of the textured surface can be controlled by adjusting the average thickness of the deposited masking materials, the gas composition, as well as the base pressure during etching. An optimum texture created by either sputter etching or reactive ion etching on a magnetic recording medium provides better wear resistance and a lower flying height of a magnetic head as compared to conventional mechanical texturing techniques. In addition, the manufacturing processes of the magnetic recording medium thus defined including the deposition of underlayer, magnetic layer and protective overcoat and the creation of surface texture can be successively performed within a single vacuum system without breaking vacuum; the present invention thus possesses the advantages of process automation, improving quality, and lowering manufacturing cost.

A manufacturing method for sputtering an anti-refection layer onto a board at low temperature has the merits of easily being implemented and easily mass-produced. The manufacturing method is used for sputtering multiple anti-refection layers onto a board. The method can be used for mass-producing anti-reflection panels as the raw material for the photo industry. The method is superior to the manufacturing method for producing nebulization anti-reflection panels. This invention utilizes the anti-reflection characteristics of the board structure that is sputtered and stacked alternatively with high index refraction layers and low index refraction layers. A continuous manufacturing process is adopted. The present invention uses plasma to clean the surface of the boards and adopts a traditional sputtering machine. Therefore, it is convenient for installing and mass-producing high quality material.

A two-stage manufacturing process for preparation of an ITO layer includes having first a transparent substrate, e.g., a glass or plastic substrate going through treatment without preheating; the substrate is then sputtering processed in a sputtering chamber under process conditions without heating up to form a amorphous state ITO film on the surface of the transparent substrate; followed with a thermal treatment at a preset temperature to turn the ITO layer into a crystalline state without compromising strength of the glass or the plastic substrate while delivering a durable ITO layer and a structure of ITO layer provided with a specific sheet resistance and/or thickness. The ITO layer produced using the present invention particularly fits to be applied in a touch screen structure.
