Abstract:
A planarization method is provided and includes the following steps. A substrate having a main surface is provided. A protruding structure is formed on the main surface. An insulating layer is formed conformally covering the main surface and the top surface and the sidewall of the protruding structure. A stop layer is formed on the insulating layer and at least covers the top surface of the protruding structure. A first dielectric layer is formed blanketly covering the substrate and the protruding structure and a chemical mechanical polishing process is then performed to remove a portion of the first dielectric layer until a portion of the stop layer is exposed thereby obtaining an upper surface. A second dielectric layer having a pre-determined thickness is formed covering the upper surface.

Claim (Index 9):
The planarization method according to  claim 8 , wherein the step of forming the stop layer includes removing the insulating layer not covered by the stop layer and therefore exposing a portion of the main surface.
