    • A method for producing a bonding wafer by ion implantation stripping method comprising a step for bonding a bond wafer having a micro bubble layer formed by gas ion implantation and a base wafer becoming a supporting substrate, and a step for stripping the bond wafer with the micro bubble layer as a boundary and forming a thin film on the base wafer, wherein the pasted wafer from which the bond wafer is stripped is heat treated in the atmosphere of an inert gas, hydrogen gas or their mixture gas, a thermal oxide film is formed on the surface of the thin film by thermally oxidizing the pasted wafer, and then the thickness of the thin film is reduced by removing the thermal oxide film. Damages and defects on the surface of a pasted wafer produced by ion implantation stripping method can be removed surely while sustaining uniformity in the thickness of a thin film on the wafer, and a method for producing a bonding wafer sufficiently applicable as a mass production technology is provided.
    • 一种用于通过离子注入剥离方法制造接合晶片的方法,包括用于结合具有由气体离子注入形成的微气泡层的接合晶片和成为支撑衬底的基底晶片的步骤,以及用于将微结晶晶片剥离的步骤 气泡层作为边界并在基底晶片上形成薄膜,其中将剥离接合晶片的粘贴晶片在惰性气体,氢气或其混合气体的气氛中进行热处理,形成热氧化膜 通过热氧化粘贴的晶片在薄膜的表面上,然后通过去除热氧化膜来减小薄膜的厚度。 通过离子注入剥离法生产的粘贴晶片的表面上的损伤和缺陷可以在保持晶片上薄膜厚度的均匀性的同时被去除,并且作为批量生产技术充分适用的制造接合晶片的方法是 提供。
