Patent ID: 8513128

Claim:
A poly opening polish process, comprising: providing a semi-finished semiconductor component comprising: a substrate; a gate disposed on the substrate; and a hard mask disposed on the gate; and a dielectric layer disposed on the substrate and covering the gate and the hard mask, the dielectric layer comprising a first dielectric layer and a second dielectric layer, the first dielectric layer being disposed on the substrate and covering the gate and the hard mask, the second dielectric layer being disposed on the first dielectric layer; and applying a first polishing process onto the dielectric layer, comprising: applying a first chemical mechanical polishing process onto the second dielectric layer so as to expose the first dielectric layer; applying a second chemical mechanical polishing process onto the first dielectric layer after the first chemical mechanical polishing process so as to expose the hard mask; and applying a dry etching process onto the hard mask after the second chemical mechanical polishing process so as to expose the gate.
