发明名称 Integrated circuit assembly with cushion polymer layer
摘要 A method of forming an integrated circuit assembly includes forming an insulator layer on a preliminary semiconductor assembly. The preliminary semiconductor assembly includes a semiconductor substrate having a first side and a second side opposite the first side, a semiconductor circuitry layer formed on the first side of the semiconductor substrate, and a conductive via extending through the semiconductor substrate from the semiconductor circuitry layer to the second side. The insulator is formed on the second side and an end of the conductive via. The method includes forming a polymer layer on the insulator layer, removing a quantity of the polymer layer sufficient to expose the end of the conductive via through the insulator layer, and forming a conductive contact on the polymer layer and the end of the conductive via.
