Abstract: A semiconductor device having a nonvolatile memory is reduced in size. In an AND type flash memory having a plurality of nonvolatile memory cells having a plurality of first electrodes, a plurality of word lines crossing therewith, and a plurality of floating gate electrodes disposed at positions which respectively lie between the plurality of adjacent first electrodes and overlap the plurality of word lines, as seen in plan view, the plurality of floating gate electrodes are formed in a convex shape, as seen in cross section, so as to be higher than the first electrodes. As a result, even when nonvolatile memory cells are reduced in size, it is possible to process the floating gate electrodes with ease. In addition, it is possible to improve the coupling ratio between floating gate electrodes and control gate electrodes of the word lines without increasing the area occupied by the nonvolatile memory cells.

Abstract: A magnetic media having a multi-layer magnetic oxide structure with an uppermost magnetic oxide layer having a very low magnetic anisotropy energy. The magnetic oxide structure includes at least three magnetic oxide layers. An upper most magnetic oxide layer structure has a magnetic anisotropy energy of less than 1×106 erg/cm3 and a saturation magnetization of greater than 300 emu/cm3. The magnetic oxide structure improves media magnetization in response to a magnetic field. The low anisotropy layer responds easily to a magnetic field. This magnetic response is then transferred to the underlying layers which have a higher magnetic anisotropy for improved robustness in maintaining magnetization over time and even in a high temperature environment.

Abstract: A process for duplex heat treatment of combined nitriding treatment and induction quenching treatment on an iron and steel material includes a chemical conversion treatment step for forming a chemical conversion film on a nitrogen compound layer formed on the iron and steel material by the nitriding treatment, after the nitriding treatment and before the induction quenching treatment. A compound layer formed on a surface of an iron and steel material by nitriding treatment is prevented from being oxidized by induction quenching, so that unevenness in film thickness between different portions of an oxidization-inhibiting film does not easily occur, with the result that a nitrogen-containing compound layer obtained after high-frequency heating remain uniformly.

Abstract: A method for manufacturing a magnetic media for perpendicular magnetic data recording. The method includes depositing a Ru layer in a pure oxygen atmosphere and then further depositing Ru in the presence of oxygen to form a thin pseudo onset layer. The pseudo onset layer can advantageously be depositing in the same deposition chamber and using the same target as that used to deposit the underlying Ru layer. This saves a great deal of manufacturing cost and complexity. The presence of the pseudo onset layer reduces grains size and increases grain separation in a high Ku magnetic layer deposited thereon, thereby increasing signal to noise ratio and decreasing magnetic core width (MCW).
