    • PURPOSE: A method for processing the surface of a semiconductor substrate is provided to etch a damage layer to form a concavo-convex shape after the semiconductor substrate is lapped, to perform a polishing process after a polishing surface area is reduced, and to completely remove the damage layer without several surface processes. CONSTITUTION: The surface of a semiconductor substrate is lapped(S100). The lapped surface of the semiconductor substrate is etched to form a concavo-convex shape(S200). The concavo-convex-shaped surface is polished(S300). [Reference numerals] (S100) Lap the surface of a semiconductor substrate; (S200) Etch into a concavo-convex shape; (S300) Perform polishing
    • 目的:提供一种用于处理半导体衬底的表面的方法,以在半导体衬底被研磨之后蚀刻损伤层以形成凹凸形状,以在研磨表面积减小之后执行抛光工艺,并且完全去除 损伤层没有几个表面处理。 构成:研磨半导体衬底的表面(S100)。 蚀刻半导体衬底的重叠表面以形成凹凸形状(S200)。 抛光凹凸形表面(S300)。 (附图标记)(S100)搭接半导体衬底的表面; (S200)蚀刻成凹凸形状; (S300)进行抛光
