Patent Number Title Of Patent Date Issued
6475650 Ferromagnetic material and magnetic apparatus employing the ferromagnetic material November 5, 2002
A ferromagnetic material can be formed in a very small size on the order of an atomic size and is capable of being stably magnetized. The ferromagnetic material comprises basic unit structures each consisting of a first atom (11), a second atom (12) of the same kind as the first atom
6366340 Electron exposure apparatus April 2, 2002
To provide an electron exposure apparatus capable of providing high resolution and performing electron exposure at high speed, integrated tips are used. Only the tips provided at ends control distances between the tips and the surface of a wafer, and the tips used for electron exposure
6299990 Ferromagnetic material and magnetic apparatus employing the ferromagnetic material October 9, 2001
A ferromagnetic material can be formed in a very small size on the order of an atomic size and is capable of being stably magnetized. The ferromagnetic material comprises basic unit structures each consisting of a first atom (11), a second atom (12) of the same kind as the first atom
6187458 Ferromagnetic fine line and magnetic apparatus thereof February 13, 2001
A ferromagnetic fine line has no loss of spontaneous magnetization even when fabricated ultra-small. The magnetization can be controlled by the proximity of the electrodes and the atomic level structure, and is protected from adsorption of impurities by embedding the ferromagnetic fi
5968677 Ferromagnetic material and magnetic apparatus employing the ferromagnetic material October 19, 1999
A ferromagnetic material can be formed in a very small size on the order of an atomic size and is capable of being stably magnetized. The ferromagnetic material comprises basic unit structures each consisting of a first atom (11), a second atom (12) of the same kind as the first atom
