Applied Materials 0010-02342 Ceramic Heater Assembly, 8" DXZ

Product Description

The 0010-02342 is an 8-inch DXZ ceramic heater assembly manufactured by Applied Materials for semiconductor vacuum process chambers. It integrates ceramic substrate, embedded heating elements, multi-zone temperature sensing components and wafer support surface. Constructed with ultra-clean vacuum-grade materials, it features low particle generation and low outgassing, designed to hold and heat 200mm silicon wafers during thin-film deposition processes. It connects to the chamber thermal controller to maintain precise and uniform substrate temperature under high vacuum plasma environments. Spare units available in market include new surplus and refurbished modules for AMAT semiconductor chamber maintenance.

Product Functions

• Mechanically support 8-inch silicon wafers inside high-vacuum process chamber during semiconductor thin-film deposition
• Multi-zone uniform heating across wafer surface to precisely control substrate temperature for stable PVD or CVD process
• Built-in temperature sensors transmit real-time thermal feedback signal to external thermal controller for closed-loop temperature regulation
• Execute recipe-defined temperature ramp, soak and cool sequences to match semiconductor process requirements
• Ultra-clean material design reduces outgassing and particle contamination to protect wafer yield in plasma environment
• Withstand repeated thermal cycling and plasma exposure inside vacuum chamber for long-term stable thermal performance
• Provide temperature fault status signal to tool host system for process interlock protection when over-temperature occurs

Application Scenarios

• Wafer substrate heating for Applied Materials DXZ series PVD process chambers in semiconductor fabs
• 200mm silicon wafer thermal control during metal deposition and dielectric film formation processes
• Preventive maintenance and spare replacement for legacy AMAT 8-inch PVD chamber heater assemblies
• Semiconductor tool chamber overhaul, cleaning and rebuild projects
• Spare inventory for wafer fabrication plants and AMAT semiconductor equipment service vendors
• On-site chamber repair for DXZ process chambers with heater open circuit or sensor failure faults

Common Problems

• Heater open circuit: burnout of embedded heating elements caused by long-term thermal cycling and plasma erosion
• Poor temperature uniformity: surface coating degradation, accumulated process residues and uneven aging of heating zones
• Temperature reading drift or loss: degradation of built-in RTD sensors or damage of internal feedthrough wiring
• Particle contamination: ceramic surface chipping, cracking and residual film peeling during repeated process cycles
• Vacuum leakage: sealing component aging and ceramic body microcracks induced by thermal expansion and contraction
• Slow thermal response: partial degradation of internal heating circuit affecting ramp-up and cooling speed
• Refurbished unit risk: hidden micro-defects, reduced thermal uniformity and shorter remaining service life vs new assembly
