    • PURPOSE: An SOI wafer production method and an SOI wafer produced in this way is produced to improve the uniformity of the thickness of SOI layer by minimizing the impact of the thickness deviation of the oxide film formed on the bond wafer. CONSTITUTION: The SOI wafer is produced in the process of: step 1, to prepare a bond wafer(2) and a base wafer(1) a supporting substrate and forming at least an oxide film on the bond wafer, and injecting hydrogen ion or a rare gas ion through the oxide film so that a fine bubble layer may be formed in the bond wafer part; step 2, to have the ion injected part and the surface of the base wafer stick together tight, and to thermo treat the bond wafer. Therefore a control is made so that the thickness deviation of the oxide film formed on the bond wafer is smaller than the depth deviation of an ion injection and the uniformity of the thickness of the SOI layer is improved.
    • 目的:制造以这种方式制造的SOI晶片制造方法和SOI晶片,通过最小化形成在接合晶片上的氧化膜的厚度偏差的影响来提高SOI层的厚度的均匀性。 构成:在以下步骤中制造SOI晶片:步骤1,制备接合晶片(2)和基底晶片(1)支撑衬底,并在接合晶片上形成至少一个氧化膜,并注入氢离子或 通过氧化膜的稀有气体离子,使得可以在接合晶片部分形成微小的气泡层; 步骤2,使离子注入部分和基底晶片的表面牢固地粘在一起,并且对接合晶片进行热处理。 因此,进行控制,使得形成在接合晶片上的氧化膜的厚度偏差小于离子注入的深度偏差,并且提高了SOI层的厚度的均匀性。

    • A method for producing a bonded wafer by the ion implantation delamination method includes at least a step of bonding a bond wafer having a micro bubble layer formed by gaseous ion implantation and a base wafer serving as a support substrate and a step of delaminating the bond wafer at the micro bubble layer as a border to form a thin film on the base wafer. After the delamination of the bond wafer, the bonded wafer is subjected to a heat treatment in an atmosphere of an inert gas, hydrogen or a mixed gas thereof, then the bonded wafer is subjected to thermal oxidation to form a thermal oxide film on the surface of the thin film, and then the thermal oxide film is removed to reduce thickness of the thin film.
