What it is
General reference — not yet source-verifiedAn electrostatic chuck (ESC) is a component used in plasma etch systems to hold a semiconductor wafer in place during processing.
How it works
General reference — not yet source-verifiedAn electrostatic chuck uses a high DC voltage applied to embedded electrodes to generate an electrostatic force that clamps the wafer to the chuck surface. The chuck typically includes a dielectric layer that insulates the electrodes and provides a flat, smooth surface for wafer contact. Helium gas is often introduced between the chuck and the wafer backside to improve thermal conduction and maintain uniform wafer temperature during etching.
The chuck is mounted inside the etch chamber and forms part of the cathode assembly. The wafer is placed on the chuck, clamped, and then cooled or heated as needed to control etch rate and uniformity.
Where it fits in the process flow
General reference — not yet source-verifiedThe chuck interfaces with the wafer handling system that loads and unloads wafers from the etch chamber. Downstream processes include cleaning, inspection, and further deposition or etching steps.
