    • The invention relates to a method for recycling a substrate with a step-like residue in a first region of its surface, in particular along the edge of the substrate, which protrudes with respect to the surface of a remaining second region of the substrate, and wherein the first region comprises a modified zone, in particular an ion implanted zone, essentially in a plane corresponding to the plane of the surface of the remaining second region of the substrate and/or chamfered towards the edge of the substrate. To prevent the negative impact of contaminants in subsequent laminated wafer fabricating processes, the recycling method comprises a material removal step which is carried out such that the surface of the substrate in the first region is lying lower than the level of the modified zone before the material removal. The invention also relates to a laminated wafer fabricating method using the recycled substrate and to a recycled substrate in which the surface of a first region lies lower than the surface of the second region.
    • 本发明涉及一种用于在其表面的第一区域,特别是沿着衬底的边缘相对于衬底的剩余第二区域的表面突出的阶梯状残留物再循环衬底的方法,以及 其中所述第一区域包括改性区域,特别是离子注入区域,基本上在与衬底的剩余第二区域的表面的平面相对应的平面中和/或朝向衬底的边缘倒角。 为了防止随后的层压晶片制造工艺中的污染物的负面影响,回收方法包括材料去除步骤,其执行为使得第一区域中的基板的表面低于材料之前的改质区域的水平 去除。 本发明还涉及使用再循环基板和第一区域的表面低于第二区域的表面的再循环基板的层压晶片制造方法。

    • A method is described for thinning a structure (200) comprising at least two wafers (201, 202) assembled one with the other, one (202) of the two wafers including channels (203) on its surface (202a) facing the other wafer (201). In order to cause thinning of the structure, a fluid is introduced into the channels (203) in a supercritical state and the fluid is passed from the supercritical state into the gaseous state. The method is also characterized in that the channels (203) do not open to the outside of the structure, the method further comprising forming from the outer surface of the structure, before introducing the fluid in the supercritical state, at least one access opening (204) to the channels (203).
    • 描述了一种用于减薄结构(200)的方法,该结构(200)包括与另一个组装的至少两个晶片(201,202),两个晶片中的一个(202)包括在其面对另一个晶片的表面(202a)上的通道(203) (201)。 为了使结构变薄,将流体以超临界状态引入通道(203),并且流体从超临界状态进入气态。 该方法的特征还在于,通道(203)不向结构外部开放,该方法还包括在将流体引入超临界状态之前,从结构的外表面形成至少一个进入开口( 204)连接到通道(203)。
