0200-09977 Quartz Cover 200mm Notch

The AMAT 0200-09977 Quartz Cover 200mm Notch is a high-purity fused quartz component designed for semiconductor plasma processing equipment. It belongs to the category of quartz cover parts, which serve as protective and environment-stabilizing elements inside etch chambers.

Engineered for 200mm wafer platforms, this component features a precision notch design, enabling accurate alignment with wafer orientation and compatibility with chamber handling mechanisms.

Manufactured under strict quality control, this quartz cover is optimized for:

● High-energy plasma exposure

● Reactive chemical environments (e.g., fluorine- and chlorine-based gases)

● Repeated thermal cycling in semiconductor processes

At Semixlab Technology, the product is produced using:

● Ultra-high purity quartz materials to minimize contamination risks

● Precision machining to ensure tight tolerances and OEM compatibility

● Advanced surface finishing to reduce particle generation

This ensures reliable and repeatable performance in demanding semiconductor manufacturing environments.

Position in Equipment and Functional Role

Installation Position

The Quartz Cover is typically installed:

● Around or above the wafer edge region

● Near the electrostatic chuck (ESC)

● Within the plasma exposure zone of the etch chamber

It serves as part of the chamber protection and edge environment control system, often working in conjunction with focus rings and shadow rings.

Core Functions

1. Chamber Protection (Primary Function)

The Quartz Cover acts as a sacrificial protective barrier, preventing direct exposure of critical components (e.g., ESC, chamber walls) to:

● Plasma ion bombardment

● Chemical corrosion

● Metal sputtering

Result: Extended lifetime of high-value chamber components and reduced contamination risk.

2. Edge Environment Stabilization

Through its geometry and placement, the component helps:

● Stabilize plasma density near the wafer edge

● Maintain consistent gas distribution in the edge zone

Impact: Improved process repeatability and reduced edge-related variability.

3. Gas Flow and By-product Management

The Quartz Cover influences:

● Local gas flow patterns

● Deposition behavior of process by-products

Benefit: Reduced unwanted polymer accumulation and improved chamber cleanliness over extended runs.

4. Notch Design for Alignment and Compatibility

The integrated notch structure enables:

● Alignment with wafer notch orientation

● Compatibility with lift pins and wafer handling systems

● Mechanical integration with adjacent edge components

Significance: Ensures stable operation and precise positioning within the chamber assembly.

Common Failure Modes

As a consumable component operating under harsh plasma conditions, the Quartz Cover is subject to predictable degradation mechanisms:

1. Plasma-Induced Erosion

● Continuous ion bombardment leads to surface roughening

● Gradual material loss alters geometry

Impact: Changes in gas flow and plasma behavior, potentially affecting process stability.

2. By-product Deposition and Contamination

● Accumulation of polymer or reaction by-products

● Deposits may flake off during operation

Impact: Particle contamination and increased defect density on wafers.

3. Thermal Stress Cracking

● Repeated heating and cooling cycles induce internal stress

● Micro-cracks may develop and propagate

Impact: Risk of sudden breakage and unplanned equipment downtime.

4. Particle Generation from Material Degradation

● Long-term exposure weakens quartz integrity

● Micro-fractures release particles into the chamber

Impact: Yield loss and reduced device reliability.
