The 0200-03233 L-COLLAR, COLUMNAR Si 1.5mm STEP (POLY) is a precision-engineered silicon chamber component used in Applied Materials (AMAT) semiconductor processing equipment to support chamber protection, plasma conditioning, and stable process performance during polysilicon and plasma-based manufacturing applications.
Installed within the process chamber, the L-collar functions as a plasma-facing consumable that helps protect critical chamber hardware from direct plasma exposure while maintaining consistent chamber geometry and process boundary conditions. In semiconductor manufacturing environments where plasma uniformity, contamination control, and repeatable wafer processing directly impact yield, maintain a properly functioning silicon collar.
Because chamber collars operate under continuous plasma exposure, ion bombardment, thermal cycling, and aggressive process chemistries, erosion, dimensional wear, surface degradation, or contamination buildup can gradually affect chamber performance. The 0200-03233 is designed to provide reliable protection and stable process conditions while helping extend the service life of adjacent chamber components.
The ESCT equivalent part number for this component is ES1099-020, supplied as a 2nd Source NEW OEM-compatible replacement designed to meet form, fit, and functional requirements aligned with the original Applied Materials component.
The 0200-03233 functions as a critical chamber protection and plasma-management component.
Core functions include:
In many Applied Materials platforms, silicon collars operate alongside focus rings, edge rings, shields, liners, electrodes, and other plasma-facing consumables that collectively support chamber performance and reliability.
