0200-36680 Upper Gas Dist Liner

The AMAT 0200-36680 Upper Gas Dist Liner is a precision quartz chamber component designed for Applied Materials (AMAT) semiconductor deposition systems. Installed within the upper gas distribution region of plasma-enhanced process chambers, this liner plays a critical role in maintaining plasma uniformity, gas flow stability, RF process consistency, and contamination control during advanced wafer fabrication.

Manufactured from high-purity fused quartz, the component is engineered to withstand aggressive plasma environments, thermal cycling, and reactive semiconductor process chemistries commonly found in PECVD and CVD applications.

At Semixlab, we provide reliable semiconductor chamber consumables and precision process parts that support stable equipment operation, preventive maintenance, and long-term process repeatability for semiconductor manufacturing facilities worldwide.

Product Basic Information

The AMAT 0200-36680 liner is typically used as part of the chamber gas distribution architecture inside AMAT plasma deposition systems. It is commonly associated with upper gas distribution assemblies where process gases and RF plasma interactions must be precisely controlled.

As a plasma-facing consumable component, the liner is subject to deposition buildup, thermal stress, and chamber cleaning exposure during normal semiconductor production cycles.

Product Structure and Features

1. High-Purity Quartz Construction

The AMAT 0200-36680 Upper Gas Dist Liner is fabricated from ultra-high-purity fused quartz material specifically selected for semiconductor plasma processing environments.

Quartz is widely used in semiconductor deposition chambers because it provides:

● Excellent plasma resistance

● Low metallic contamination risk

● High thermal stability

● Superior dielectric insulation

● Strong RF transparency

● Compatibility with reactive chamber chemistries

These material characteristics are essential for maintaining stable process conditions during high-volume wafer manufacturing.

2. Precision Ring-Shaped Geometry

As shown in the product image, the liner features a precision-machined circular ring structure designed for integration within the chamber gas distribution assembly.

The geometry is engineered to support:

● Uniform process gas diffusion

● Stable plasma boundary formation

● Controlled RF field distribution

● Consistent chamber flow dynamics

● Optimized wafer edge process performance

The dimensional precision of quartz chamber hardware is extremely important in semiconductor equipment because even small geometric deviations may influence plasma symmetry and film deposition uniformity.

3. Plasma-Facing Surface Design

The upper gas distribution liner operates directly within the plasma processing region and is continuously exposed to:

● Reactive plasma radicals

● Deposition byproducts

● RF energy

● Chamber cleaning gases

● High-temperature process cycles

To support long-term chamber stability, the liner surface is designed to minimize:

● Particle generation

● Surface erosion

● Plasma instability

● Deposition flaking

● Contamination transfer

Its smooth quartz surface also helps improve chamber cleanliness and process repeatability during extended production runs.

4. Engineered for Semiconductor Process Stability

Unlike conventional industrial quartz components, semiconductor chamber liners must maintain strict process compatibility under highly controlled manufacturing conditions.

The AMAT 0200-36680 liner is engineered to support:

● Stable PECVD process performance

● Consistent plasma ignition characteristics

● Controlled gas residence time

● Reduced chamber drift

● Improved wafer-to-wafer repeatability

These factors are critical in advanced semiconductor fabrication environments where process uniformity directly impacts yield and device performance.

The AMAT 0200-36680 Upper Gas Dist Liner is a high-purity quartz chamber component designed for semiconductor PECVD and CVD process systems. Its precision-engineered structure supports gas distribution stability, plasma control, RF consistency, and contamination reduction within advanced deposition chambers.

As a critical plasma-facing consumable, this quartz liner plays an important role in maintaining chamber repeatability, process uniformity, and semiconductor manufacturing reliability.
