发明名称 Backside integrated circuit die surface finishing technique and tool
摘要 A method for preparing a semiconductor die for analysis comprises providing a semiconductor die having a connector on one side and an opposite, backside surface to be analyzed, providing a polishing pad for polishing the backside surface of a semiconductor die, providing a rotatable spindle for securing the polishing pad, and providing a constant force actuator on the spindle, the constant force actuator being adapted to provide constant force between the polishing pad and the backside surface of the die. The method then includes contacting the backside die surface with the polishing pad, rotating the spindle and polishing pad, and polishing the backside surface of the die by while maintaining the substantially constant force of the polishing pad on the die backside surface with the constant force actuator.
