    Abstract: A method for controlling a wafer warpage by using a SiGe layer deposition and a wafer manufactured thereof are provided to offset the wafer warpage by depositing a Si1-xGex layer on a rear of the wafer on which a warpage is generated. A Ge mol content % and a thickness of a Si1-xGex layer(G) required for offsetting a warpage according to a warpage of a wafer(W) are quantitatively analyzed. The wafer requiring a warpage control is loaded into a deposition chamber of the Si1-xGex layer. The Si1-xGex layer is deposited on a rear of the wafer not a processing surface. The warpage is generated toward an upper direction on the center of the wafer when the processing surface is directed to the upper direction. The Ge mol content % and the thickness of the Si1-xGex layer are controlled less than preset critical values. The preset critical values with respect to the Ge mol content % and the thickness of the Si1-xGex layer are 30 % and 1 mum, respectively.

    Abstract translation: 提供了通过使用SiGe层沉积来控制晶片翘曲的方法及其制造的晶片,以通过在其上产生翘曲的晶片的后部沉积Si1-xGex层来抵消晶片翘曲。 定量分析根据晶片(W)的翘曲来抵消翘曲所需的Ge摩尔含量%和Si1-xGex层(G)的厚度。 需要翘曲控制的晶片被加载到Si1-xGex层的沉积室中。 Si1-xGex层沉积在晶片的后面而不是处理表面。 当处理表面指向上方时,朝向晶片中心的上方产生翘曲。 将Ge摩尔含量%和Si1-xGex层的厚度控制在预设临界值以下。 相对于Ge摩尔含量%和Si1-xGex层的厚度的预设临界值分别为30%和1μm。
