    摘要: A method of fabricating a magnetic bubble memory device is disclosed in which a desired portion of a surface region in a magnetic bubble film for magnetic bubbles is implanted with hydrogen ions with an ion dose of 2.5.times.10.sup.16 to 1.times.10.sup.17 cm.sup.-2, the surface of magnetic bubble film thus formed is covered with a film, and then the magnetic bubble film is annealed. According to this method, a reduction in propagation margin due to annealing is effectively prevented, and it is possible to form a magnetic bubble memory device of the contiguous disk type which is excellent in thermal stability.

    摘要: In a magnetic bubble device, a strain layer formed on the surface of a magnetic bubble garnet film by ion-implantation is required to have anisotropy field of great strength in the in-plane direction for driving magnetic bubbles. For preventing the effective anisotropy field change from being decreased by heat treatment, ion species having large mass and projected standard deviation not greater than 1000 .ANG. are implanted. The ion species are preferably selected from He to Kr in the periodic table. The heat treatment is effected at a temperature in a range of 450.degree. C. to 900.degree. C.

    摘要: There have been known various methods for controlling the magnetic anisotropy of a magnetic film with a magnetic field being applied thereto. In accordance with the present invention, the magnetic anisotropy is controlled by implanting ions into the magnetic film while applying a magnetic field thereto. The direction for applying the magnetic field can be arbitrarily selected, for example, along an inplane direction of the magnetic film and along a direction vertical thereto. The magnetic anisotropy can be controlled only in the desired areas by limiting the areas to which ions are implanted with a mask disposed on the magnetic film.

    摘要: A mask structure has two (or more) groups of device patterns formed on one transparent support plate. Each of the device patterns has a transparent partial pattern. One or both of the groups of device patterns are provided with phase shifting patterns for improvement of the resolution in the lithography. The transparent partial pattern in each of the device patterns in each of the device pattern groups is determined such that each of the transparent partial patterns held by one of the device pattern groups is adapted for combination with one transparent partial pattern held by the other device pattern group by two or more times of transmission of an exposure beam through the mask structure. Manufacturing of solid-state devices is possible by use of the mask structure, in which exposure of a photo-sensitive film on a substrate to an exposure beam through the mask structure is repeated two or more times with a relative position between the mask structure and the substrate being changed.
