摘要： PROBLEM TO BE SOLVED: To provide an Si substrate for magnetic recording medium having excellent surface flatness without making a processing process and deposition process of a magnetic recording layer complex, as well as a thermal conductivity that is unchanged from a bulk substrate of a single crystal and a polycrystal. SOLUTION: A metal film is deposited (S7) on a polycrystalline silicon substrate after rough polishing (S6) and silicidated or silicon-alloyed (S8). Thereafter, the film is subjected to precision polishing (S9) such as CMP polishing to increase the flatness of the substrate. Accordingly, the Si substrate for a magnetic recording medium obtains a flat and smooth surface without being influenced by a difference between crystal orientations of the polycrystalline grains and the presence of crystal grain boundary, and obtains heat resistance and a thermal conductivity approximately equivalent to a bulk Si substrate.

摘要： PROBLEM TO BE SOLVED: To provide an Si substrate for magnetic recording medium, which has sufficient shock resistance, prevents machining processes and film deposition processes of a magnetic recording layer from becoming complex, has improved surface planarity, and can reduce costs. SOLUTION: Etching is not performed in the process of planarizing a polycrystalline Si wafer, but only mechanical grinding is performed for planarization (S104, S106). This is because, since the etching rate is crystal-face dependent, etching of the polycrystalline Si wafer inevitably results in formation of steps because of different crystal-face orientations of individual crystal grains exposed on a surface of the wafer, which hinders precision surface planarization. Subsequently, the Si wafer surface is coated with an oxide film to form an Si wafer with oxide film prior to the final polishing stage (S107) and then a surface of the oxide film is planarized, to obtain a planar substrate (Si substrate with oxide film) having no steps on the surface thereof (S108).

摘要翻译：要解决的问题：为了提供具有足够的抗冲击性的磁记录介质的Si衬底，防止磁记录层的机械加工和膜沉积过程变得复杂，具有改善的表面平面性，并且可以降低成本。解决方案：在平坦化多晶Si晶片的过程中不进行蚀刻，但是仅进行用于平坦化的机械研磨（S104，S106）。这是因为，由于蚀刻速度是晶面依赖的，所以多晶硅晶片的蚀刻不可避免地导致步骤的形成，这是由于晶片表面上暴露的各个晶粒的晶面取向不同，这阻碍了精密的表面平坦化。随后，在最终抛光阶段之前，用氧化膜涂覆Si晶片表面以形成具有氧化膜的Si晶片（S107），然后使氧化膜的表面平坦化，从而获得平面基板（具有氧化物的Si基板薄膜），其表面没有台阶（S108）。版权所有（C）2009，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To provide a silicon substrate for magnetic recording medium which reduces cost reduction while having sufficient impact resistance and excellent surface flatness without complicating working process and deposition process of a magnetic recording layer.
SOLUTION: A method for manufacturing the silicon substrate for magnetic recording medium comprises: a step for coating a silicone based material and a solution including organosilica on a surface of polycrystal silicon substrate after roughly polishing (S106) to make a thin film for shielding steps and crystal grain boundaries, a step for forming an SiO
2 film by treating the thin film with heat at an appropriate temperature to vaporize organic constituents (S107), and a step for enhancing the flatness of the substrate by finely polishing the SiO
2 film (S108) such as CMP polishing. Herewith a flat and smooth surface (both square mean values of waviness and microwaviness are equal to or less than 0.3 nm) is obtained without being affected by difference of crystal orientation and existence of crystal grain boundaries of the polycrystal grains.
