AMAT 0040-01239
Product Name: Electrostatic Chuck (ESC) for Etch/Deposition Systems Product Introduction: The 0040-01239 is an Electrostatic Chuck (ESC) assembly used in various Applied Materials process modules (both etch and deposition). The ESC is the platform on which the wafer sits inside the vacuum chamber. It uses electrostatic force (Coulomb or Johnsen-Rahbek effect) to hold the wafer firmly in place, even under high vacuum and during plasma bombardment. It also typically incorporates a helium backside cooling system to control wafer temperature. Technical Specifications:
- System Compatibility: Multi-chamber platforms (e.g., DPS, Eterna)
