0200-36682 Liner Quartz Lower Gas Dist

The AMAT 0200-36682 Liner Quartz Lower Gas Dist is a precision-engineered quartz liner component designed for Applied Materials (AMAT) semiconductor deposition systems. This part is commonly associated with the lower gas distribution region within plasma-enhanced deposition chambers, particularly in PECVD and dielectric thin-film processing applications.

Manufactured from high-purity fused quartz, the liner serves as a critical chamber consumable that supports plasma stability, gas flow uniformity, contamination control, and process repeatability in advanced semiconductor manufacturing environments.

At Semixlab, we provide high-quality semiconductor spare parts and chamber consumables that meet the demanding standards of wafer fabrication facilities, equipment refurbishers, and semiconductor process engineers worldwide.

Product Basic Information

The AMAT 0200-36682 liner is typically installed within the lower gas distribution assembly of deposition chambers where process gases, plasma dynamics, and thermal stability must be precisely controlled.

Because quartz components operate directly inside harsh plasma environments, they are classified as high-value consumable process parts requiring periodic inspection and replacement.

Core Functions in Semiconductor Equipment Processes

1. Plasma Boundary Stabilization

One of the most important roles of the AMAT 0200-36682 liner is to help define and stabilize the plasma boundary inside the deposition chamber.

In PECVD and CVD systems, plasma behavior directly affects:

● Film thickness uniformity

● Deposition rate consistency

● Edge profile control

● Wafer yield performance

● Critical dimension stability

The quartz liner helps maintain a controlled plasma environment by providing a stable dielectric boundary around the lower gas distribution region.

2. Gas Flow Distribution Optimization

The liner also contributes to optimized gas flow management within the chamber.

Uniform gas distribution is essential for:

● Even film deposition

● Reduced process variation

● Stable wafer-to-wafer repeatability

● Improved process consistency across production batches

By supporting the chamber’s gas diffusion architecture, the lower gas distribution liner helps ensure consistent precursor delivery across the wafer surface.

3. Particle and Contamination Control

Particle contamination remains one of the most critical concerns in semiconductor manufacturing.

As a plasma-facing chamber component, the quartz liner helps reduce:

● Chamber particle generation

● Metal contamination risks

● Deposition flaking

● Plasma-induced debris formation

High-purity quartz materials are widely used because they minimize contamination transfer to the wafer during advanced deposition processes.

4. RF and Electrical Isolation

Quartz liners also play an important role in RF field management.

Because fused quartz is electrically insulating while remaining RF transparent, it enables:

● Stable RF coupling

● Controlled plasma sheath behavior

● Reduced arcing probability

● Improved chamber impedance stability

This contributes to more reliable chamber matching and improved process repeatability during long production runs.

5. Support for Advanced Semiconductor Manufacturing

Components such as the AMAT 0200-36682 are essential for maintaining high process stability in advanced semiconductor fabrication environments, including:

● Logic device manufacturing

● Memory fabrication

● Advanced dielectric deposition

● Thin-film processing

● High-volume wafer production

As process nodes continue to shrink, chamber consumables like quartz liners become increasingly important for maintaining process precision and yield performance.
