Patent
Projection exposure apparatus and method which uses multiple diffraction gratings in order to produce a solid state device with fine patterns
TL;DR: In this paper, a mask pattern is formed near the substrate surface by the interference of beams diffracted by the first grating, which produces the effect of virtually increasing the NA of the optical system by up to a factor of two, making it possible to manufacture LSIs with fine patterns.
Patent
Disk array apparatus
TL;DR: A disk array is a disk array consisting of a rack-shaped basic frame and a plurality of disk boxes that can be inserted into and pulled out of the basic frame depth-wise.
Patent
Perpendicular magnetic recording medium and magnetic storage device
TL;DR: In this article, a magnetic recording medium suitable for use with a microwave assisted magnetic recording head and suitable for such recording and a method for manufacturing the same is presented, provided that the recording medium is a magnetic medium with a magnetic head.
Patent
