Inventor: SAITO JUN
IPC: G11B11/10
Filed: 1989-11-10
Abstract: PURPOSE:To increase C/N by laminating a 1st layer and a 2nd layer consisting of a perpendicularly magnetized layer having the Curie point Tc2 lower than the Curie point Tc1 thereof and inverting the magnetization of the 1st layer so that the magnetization of the 2nd layer is made to follow up the magnetization of the 1st layer by this magnetization. CONSTITUTION:The direction upward of the layer plane is designated as 'A direction' and the direction downward thereof as 'backward A direction'. The medium temp. rises to the temp. lower than the Curie point Tc1 of the 1st layer when the medium is irradiated with the beam of a low level. A mark having the magnetization of the 'backward A direction' is formed in the 1st layer by the effect of the residual magnetization of the 'A direction' of the 2nd layer therein. The medium temp. increases to a high temp. and the magnetization of the 1st layer is in the same direction as the effect of the recording magnetic field when the medium is irradiated with the beam of a high level. The magnetization of the 2nd layer is the direction stable to the 1st layer made into the same direction as the direction of the recording magnetic field by the temp. lowered from its own Curie point Tc2. As a result, the mark that the 2nd layer has the magnetization of the 'A direction' and the 1st layer has the magnetization of the 'backward A direction' is formed. The overwritable medium is obtd. in this way.

Filed: 1986-12-11
Abstract: PURPOSE:To obtain a diffracted-light signal with a high SN ratio by a method wherein, when a pattern, for alignment use, on a first object is illuminated by a first beam of coherent light and is then transcribed to a prescribed part of a photosensitive layer on a second object, the prescribed part of the photosensitive layer is illuminated simultaneously by a second beam of coherent light at an illuminating angle which is different from the angle of the first beam of coherent light. CONSTITUTION:When a pattern 6, for alignment use, on a first object 3 is illuminated by a first beam SIGMA1 of coherent light and is then transcribed to a prescribed part of a photosensitive layer 7 on a second object 4, the prescribed part is illuminated by a second beam SIGMA2 of coherent light at an angle which is different from the angle of the first beam SIGMA1 of coherent light; this second beam of coherent light is made to interfere with the first beam SIGMA1 of coherent light; as a result, a pattern, for alignment use, in the form of a latent image of the first object 3 is formed three-dimensionally on the photosensitive layer 7 on the second object 4. For example, if the pattern 6, for alignment use, on a reticle 3 is illuminated from an illuminating device 2, the pattern 6, for alignment use, is transcribed onto a wafer 4 through an image-forming device 5. During this process, the distribution showing the refractive index and the transmissivity corresponding to the distribution of an interference fringe formed by the beam SIGMA1 and SIGMA2 is formed inside the resist layer 7 of the wafer 4.

Here, the exposed surface of the crystalline silicon film 109 is rid of the contaminated region in its surface layer. As a result, the unevenness of the surface is reduced, and the surface is brought into a very clean state. For this reason, a verey clean crystalline silicon film 109-oxide film 110 boundary 111 is obtained, by covering the crystalline silicon film 109 with the oxide film 110 without exposing it to the air.
