titleOfInvention |
Bottom-up material formation for planarization |
abstract |
The present disclosure provides a method for planarization. The method includes providing a substrate having a top surface and a trench recessed from the top surface; coating a sensitive material layer on the top surface of the substrate, wherein the sensitive material layer fills in the trench; performing an activation treatment to the sensitive material layer so that portions of the material layer are chemically changed; and performing a wet chemical process to the sensitive material layer so that top portions of the sensitive material layer above the trench are removed, wherein remaining portions of the sensitive material layer have top surfaces substantially coplanar with the top surface of the substrate. |
