Abstract:
Provided is a light-emitting glass which is applicable to, e.g., white illuminators including a light-emitting diode as a light source, and which emits light of a warm white color when irradiated with near ultraviolet light and combines long-term weatherability with high heat resistance. Also provided are a light-emitting device equipped with the light-emitting glass and a process for producing the light-emitting glass. The light-emitting glass includes, as the base glass, borosilicate or silicate glass having a separated-phase structure, whereby the base glass is efficiently doped with, for example, transition metal ion clusters which emit light of a warm white color upon irradiation with near ultraviolet light. With this glass, it is possible to attain increases in excitation wavelength and emission wavelength. The glass thus emits, based on a multiple scattering effect, high-intensity light of a warm white color upon irradiation with near ultraviolet light. Furthermore, since the light-emitting glass includes borosilicate or silicate glass, which is a common glass material, as the constituent material, it is possible to inexpensively provide a fluorescent material combining long-term weatherability with respect to ultraviolet rays, etc. with resistance to high temperatures.

Abstract:
The present invention provides a manufacturing method of a magneto-resistance effect element, in which the step coverage of a formed film can be enlarged and also the film can be deposited in a low temperature range. In an embodiment of the present invention, an insulating protective layer is formed on a multilayered structure by a plasma CVD apparatus in which a plasma source and a film deposition chamber are separated from each other by a partition wall plate. According to the present method, it is possible to deposit the protective layer without inviting the degradation of a magnetic characteristic and also to perform low temperature film deposition even at a temperature lower than 150° C. Hence, it is possible to deposit the protective layer while leaving resist and also to reduce the number of steps in the manufacturing of the magneto-resistance effect element having a multilayered structure.

The object of the present invention is to provide a masking material for dry etching, which is suitable for fine processing of a magnetic film as thin as a few nm such as NiFe or CoFe constituting a TMR film and capable of simplifying the process for producing a TMR element and reducing production costs related to facilities and materials. This object was solved by a masking material for dry etching of a magnetic material by using a mixed gas of carbon monoxide and a nitrogenous compound as etching gas, which comprises a metal (tantalum, tungsten, zirconium or hafnium) with a melting or boiling point increasing upon conversion thereof into a nitride or carbide.

Abstract:
In a method of manufacturing a magneto-resistance element having a multi-layer film including magnetic layers, TaOx generated on the surface of the Ta mask is prevented from peeling off when etching is performed on the multi-layer film using an etching gas containing oxygen atoms.When a Ta mask which is used at the time of dry etching performed on the multi-layer film including magnetic layers with an etching gas containing oxygen atoms is formed by sputtering, the Ar gas pressure is set to be 0.1 Pa to 0.4 Pa.
