Technical Specifications:
Product Introduction: This part number typically refers to a comprehensive kit of consumable spare parts required for the preventive maintenance (PM) of a specific process chamber. It ensures that all wear-prone components are replaced simultaneously to restore the chamber to its "as-new" performance specifications.1. Kit Contents (Typical):
Product Introduction: This is a high-precision heating assembly, often integrated into the electrostatic chuck or wafer pedestal. It uses resistive heating elements embedded within a ceramic body (usually Aluminum Nitride for high thermal conductivity) to heat the wafer to processing temperatures ranging from room temperature to several hundred degrees Celsius. Technical Specifications:
Product Introduction: The Electrostatic Chuck is the heart of the wafer handling system in plasma processors. It holds the wafer securely in place using electrostatic force (Johnsen-Rahbek or Coulomb force) generated by high voltage DC. It also typically incorporates a helium backside cooling system to control the wafer temperature during high-power processing. Technical Specifications:
Product Introduction: The Chamber Liner is a replaceable protective shell that lines the interior walls of the vacuum chamber. It protects the expensive main chamber body (usually stainless steel) from plasma sputtering, chemical corrosion, and thermal stress. Liners also act as a ground plane and can influence plasma uniformity. Technical Specifications:
Product Introduction: The Lift Pin Assembly is a mechanical subsystem located within the wafer support pedestal (susceptor). It consists of pins that move vertically to lift the wafer off the pedestal surface, facilitating robotic handoff and cooling. This mechanism ensures the wafer does not stick to the pedestal due to vacuum chucking or thermal bonding. Technical Specifications:
Product Introduction: The Throttle Valve is a precision vacuum control device located between the process chamber and the vacuum pump. It regulates the chamber pressure by adjusting the aperture size of the orifice. This component is vital for controlling the mean free path of gas molecules, which directly affects plasma density, etch rate, and anisotropy. Technical Specifications:
Product Name: Edge Ring / Focus Ring Product Introduction: The Edge Ring is a consumable or semi-permanent component installed at the periphery of the wafer pedestal in an etch or deposition chamber. It protects the chamber walls from plasma erosion and controls the plasma sheath profile at the wafer edge, preventing edge exclusion and ensuring uniform processing across the entire wafer surface, including the bevel area. Technical Specifications:
Product Name: RF Impedance Matching Network (Matchbox) Product Introduction: This is a sophisticated RF matching network designed to maximize power transfer between the RF generator and the plasma load. It automatically tunes the impedance to ensure that reflected power is minimized, protecting the generator and ensuring process stability. This unit is a core component of the RF delivery system in plasma processing tools. Technical Specifications:
Product Name: Gas Distribution Assembly / Showerhead Electrode Product Introduction: This component is a critical part of the plasma processing chamber, specifically designed for semiconductor etch and deposition applications. It serves as the upper electrode and gas distribution system, ensuring uniform delivery of process gases into the plasma zone. The assembly is engineered to withstand harsh chemical environments and high thermal loads while maintaining precise plasma density control. Technical Specifications:
