Definitions
- the present invention relates to a thin film for an optical information recording medium and a method for producing the same.
- a film when a film is formed by sputtering, direct current (DC) sputtering can be performed, arcing during spattering is reduced, and particles generated due to this can be reduced.
- phase change optical disk technology which is a high-density optical information recording medium that can be read and written without the need for a magnetic head, has been developed, and interest has rapidly increased.
- These optical disks are classified into three types: ROM (read-only) type, R (write-once) type, and RW (rewrite it ab 1 e) type.
- ROM read-only
- R write-once
- RW read it ab 1 e
- Phase-change optical discs record and reproduce information by heating the recording thin film on a substrate by irradiating a laser beam and causing a crystallographic phase change (amorphous crystal) in the structure of the recording thin film. More specifically, information is reproduced by detecting a change in reflectance caused by a change in optical constant between the phases.
- the above-mentioned phase change is performed by irradiating a laser beam with a diameter of several hundred nm to several ⁇ m.
- a laser beam of 1 ⁇ m passes at a linear velocity of 10 m / s
- the time at which a point on the optical disk is irradiated with light is 10 Ons. It is necessary to detect the reflectance.
- heating and quenching are repeated not only for the recording layer but also for the surrounding dielectric protective layer and the aluminum alloy reflective film. Become.
- phase change optical disks because the protection of G e- S b- T e system, etc. on both sides of the zinc sulfide Kei oxides recording thin film layer (Z n S ⁇ S i 0 2) based high-melting dielectrics It has a four-layer structure sandwiched between layers and further provided with an aluminum alloy reflective film.
- the reflective layer and the protective layer are required to have an optical function that increases the absorption between the amorphous part and the crystalline part of the recording layer and has a large difference in reflectance. Function is required, as well as the function of controlling the thermal conditions during recording (see “Optical J 26, Issue 1, Page 9: L5”).
- the protective layer of the high-melting-point dielectric is resistant to repeated thermal stresses caused by temperature rise and cooling, and furthermore, it is necessary to prevent such thermal effects from affecting the reflective film and other parts.
- the material itself must be thin, have low reflectivity, and have toughness that does not deteriorate. In this sense, the dielectric protective layer plays an important role.
- the dielectric protection layer is usually formed by a sputtering method.
- a substrate composed of a positive electrode and a negative electrode is opposed to a target, and a high voltage is applied between them in an inert gas atmosphere to generate an electric field.
- the ionized electrons collide with the inert gas to form plasma, and the cations in the plasma collide with the surface of the target (negative electrode) and strike the target constituent atoms, and the ejected atoms face each other. It uses the principle that a film is formed by adhering to the substrate surface.
- ZnS—Si 2 which is generally used mainly for the protective layer of a rewritable optical information recording medium, has excellent characteristics in optical characteristics, thermal characteristics, adhesion to the recording layer, and the like. Is widely used because it has However, rewritable D VD, in addition to shortening the wavelength of the laser wavelength, an increase in the number of times of rewriting, larger capacity, recording speed has been demanded strongly, conventional Z n S- S i 0 2 the characteristic Is becoming inadequate.
- ZnS-S i 0 2 are disposed in contact with ZnS-S i 0 2 is also a protective layer material reflective layer, by diffusion of the sulfur component from the ZnS-S i 0 2, pure A g or A g alloy reflective layer material is Corrosion degradation has been a factor in causing deterioration of characteristics such as the reflectance of the optical information recording medium.
- an intermediate layer mainly composed of nitride or charcoal is provided between the reflective layer and the protective layer, and between the recording layer and the protective layer. Therefore, there has been a problem that the throughput and cost increase due to this.
- the protective layer material Z nS-S I_ ⁇ 2 the same characteristics, materials are required which do not contain Z n S. Further, S I_ ⁇ 2, since prone also reduced and abnormal discharge deposition rate, it is desirable not added.
- the homo-mouthed gas compound Since the homo-mouthed gas compound has a complicated layered structure, it is characterized in that the amorphous property at the time of film formation is stably maintained. In this respect, it has the same effect as the addition of SiO 2 .
- the transparent at the used wavelength region, refractive index ZnS-S I_ ⁇ has the property that close to 2.
- the protective layer material ZnS-S i 0 2 reduce or eliminate its effects of sulfur components in Rukoto replaced mainly to the material of the oxide-based, characteristic improvement and the optical information recording medium Productivity improvement was expected.
- a getter for use see Japanese Patent No. 2695605).
