    • PURPOSE: A semiconductor wafer and a method of manufacturing a semiconductor device are provided to improve the manufacturing efficiency of the semiconductor device by using commonly a transportation system without any change before and after adhering a support plate to the semiconductor wafer and relaxing finish accuracy of the semiconductor wafer and positioning accuracy of the semiconductor wafer and the support plate. CONSTITUTION: A separation part(4a) is formed on a peripheral part of a semiconductor wafer(1). The separation part has a notch deeper than a finished thickness of the semiconductor wafer obtained by removing partially a rear surface thereof. The separation part has a length which extends radially outward from a flat surface(1a) of the semiconductor wafer. The length is greater than a total sum of a maximum-minimum difference between finish allowances of diameters of the semiconductor wafer and the support plate, which has substantially the same diameter as the diameter of the semiconductor wafer, and a maximum value of a positioning error between the semiconductor wafer and the support plate when the semiconductor wafer and the support plate are adhered to each other.
    • 目的:提供一种半导体晶片和半导体器件的制造方法,以在将支撑板粘附到半导体晶片之前和之后,通过使用通常的输送系统来提高半导体器件的制造效率,并且放松了半导体器件的精加工精度 半导体晶片和半导体晶片和支撑板的定位精度。 构成:在半导体晶片(1)的周边部分上形成分离部分(4a)。 分离部分具有比通过部分地去除其后表面而获得的半导体晶片的成品厚度更深的凹口。 分离部具有从半导体晶片的平坦表面(1a)径向向外延伸的长度。 该长度大于半导体晶片和支撑板的直径的最终 - 最小差异的总和,其总直径与半导体晶片的直径基本相同,并且定位误差的最大值 当半导体晶片和支撑板彼此粘合时,在半导体晶片和支撑板之间。
