Abstract

PURPOSE:To provide a thin film with high orientation, by a method wherein the film is formed by eliminating atoms that do not incident in the vertical direction agaist a substrate. The method is related to the dry process such as the sputtering, the vacuum deposition and the ion plating processes. CONSTITUTION:RF diode sputtering device is used to form film, and it is fully baked. Before starting of sputtering, the vacuum degree in a belljar must be made less than 5.0X10<-7> Torr. A mask made of stainless steel is attached on the front surface of a substrate. Film is formed for each mask Fig (d), (e) and (f) show-the masks eliminating the atoms that incidents in the inclined direction. H-cut mask is used to form film on the atoms that incident in the vertical direction against the subtrate. The length of a pipe 4 is in order of (d), (e), (f). The angle between the center P of the substrate 3 and the upper edge of the pipe 4, that is potential angle alpha from the substrate center becomes 30 deg. for (d),40 deg. for (e), and 60 deg. for (f). The film made by using the masks is I0002/d larger than the one made without using the masks, and its crystallizability as well as the orientation in the C axis direction is improved.

In addition to fabrication factors such as deposition rate, it has been found that the angle of incidence of the incident atoms with respect to the substrate has a significant effect on the orientation of the film. When the angle of incidence of incident atoms on the substrate has many components parallel to the substrate, the C-axis orientation is limited and % [0001
) plane, but also [1010] plane and (xoig plane) are deposited parallel to the substrate, and the C-axis orientation of the film is significantly reduced.
It was observed that the magnetocrystalline anisotropy in the direction perpendicular to the film surface decreased. On the other hand, when forming II by removing all of the incident atoms whose incident angle has many components parallel to the substrate and using incident atoms whose main component is perpendicular to the substrate, the C-axis It was found that the orientation was improved and the crystalline magnetic anisotropy was improved. In this way, the C-axis orientation of the film can be clearly improved by providing a shield in front of the substrate to remove atoms incident on the substrate in a direction deviating from the perpendicular direction.

First, the characteristics of the film produced using ① Ka)-r will be described. FIG. 2(a) shows the complete X-ray diffraction patterns (using CuKa rays) of the film produced using the mask of (a) and the film produced without using the mask.

The above is the result of removing the vertically incident component and forming a film mainly on the obliquely incident component.Next, in contrast to this method, when using an H-cut mask, the film is formed mainly on the vertically incident component. Let's talk about the case.

In the X-ray diffraction patterns of the films produced using R-cut masks (d), (e), and (f), only the (0002) diffraction line was observed, indicating that the films were C-axis oriented. In order to evaluate the crystallinity in the direction perpendicular to the substrate surface, the degree of (0002) diffraction iut per unit film thickness is shown in FIG. From this figure, the film produced using the H-cut mask has a lower weight of 1000 g/m compared to the nine films produced without using a mask.
d is large, especially a mask with a viewing angle of 60° (mask f
) is found to have a value about 10 times larger. In this way, the film produced using the H-cut mask has the same crystallinity in the C-axis direction.

As explained above, if the atoms incident perpendicularly to the substrate are removed and the film is formed mainly by obliquely incident atoms, the C-axis orientation deteriorates significantly, whereas if all obliquely incident atoms are removed and the film is formed mainly by obliquely incident atoms, When the film is formed mainly by atoms, the C-axis orientation is significantly improved.

The film produced using a mask has larger Mr (±) and /Mr (//) and improved C-axis orientation compared to a film that does not use a mask. Furthermore, even with a membrane using a mask,
For films using a tilted mask, use of a right-angled mask is more effective in terms of C-axis orientation. In addition, it is preferable that the inclination angle of the partition plate or hollow tube in the shield is 115 to 5 times the rotation angle per second of the substrate. [Example 7] Co-Cr l [ ' was created. Before deposition, thoroughly bake the chamber and

As shown in Examples 1 and 2.7, when forming a thin film by a dry method, a shield is used to remove atoms incident on the substrate from directions deviating from the perpendicular direction, and a target or an evaporation source is used. When placed between the two, the orientation of the thin film is significantly improved. On the other hand, if the perpendicularly incident component is removed and a film is formed mainly of obliquely incident atoms, the orientation of the film will be significantly degraded. Therefore, in the present invention, it is an essential requirement to remove all obliquely incident atoms during film formation, and when this method is used, the orientation of the film is significantly improved. -Ru, Co-Cr film, by using the present invention, 5. As a result of improved C-axis orientation and improved crystalline magnetic anisotropy in the direction perpendicular to the film surface, there is a further advantage in producing media that can increase recording density. The manufacturing method had the disadvantage that it could only produce a film in which the M-H loop was not saturated even with an external magnetic field of 10 KOe, but by using the present invention, the external magnetic field could be reduced to 5 KOe.
A film that is saturated even with K Oe could be produced, making it possible to remove high-density inhibiting factors.

Examples 3 to 7 were attempted in order to make it possible to manufacture an all-magnetic disk according to the present invention. As I will state again here, the requirement of the present invention is to remove obliquely incident atoms, and the methods described in Examples 3 to 7 are just one example of this. It is clear that the method of installing the shield between the evaporation sources is applicable to the present invention regardless of the shape of the shield.
