Manufactured from ultra-high purity fused quartz, this component plays a critical role in maintaining a clean and stable deposition environment by minimizing contamination and ensuring consistent plasma behavior.

At Vetek Semiconductor, we provide precision-engineered quartz parts with strict material control and dimensional accuracy, offering reliable alternatives for semiconductor fabs and equipment service providers.

Key Specifications:

Process Application & Chamber Position

This quartz cover is specifically designed for PVD sputtering processes, widely used in semiconductor manufacturing for metal thin film deposition such as aluminum (Al), titanium (Ti), and copper (Cu).

Chamber Position

The component is installed in the upper section of the PVD chamber, commonly referred to as the top cover region, where it is exposed to:

● Plasma discharge zones

● Process gas flow paths

● Metal particle deposition environments

Functional Role in the Chamber

Within the chamber structure, the Cover Top Quartz serves as a non-metallic protective barrier and insulating element, positioned above the wafer and near the target region.

Its placement is critical for:

● Shielding sensitive chamber components from metal deposition

● Maintaining electrical insulation in RF plasma environments

● Supporting stable and repeatable process conditions

Core Functions & Performance Advantages

1) Contamination Control

During PVD processes, sputtered metal atoms tend to deposit not only on wafers but also on internal chamber surfaces.

This quartz cover:

● Acts as a sacrificial protective layer

● Prevents metal buildup on critical chamber structures

● Reduces particle generation and cross-contamination

Result: Improved wafer yield and process cleanliness

2) Plasma Stability & Electrical Insulation

Thanks to its excellent dielectric properties, high-purity quartz ensures:

● Stable RF field distribution

● Reduced risk of electrical interference

● Consistent plasma density across process cycles

Result: Enhanced film uniformity and repeatability

3) Superior Material Purity

Vetek Semiconductor utilizes ultra-high purity quartz materials to minimize impurity introduction.

● Low metallic contamination

● Minimal outgassing under vacuum conditions

● Suitable for advanced semiconductor nodes

Result: Meets stringent fab-level cleanliness standards

4) Excellent Plasma & Thermal Resistance

The component is engineered to withstand:

● Plasma erosion and ion bombardment

● Repeated thermal cycling

Result: Longer service life and reduced maintenance frequency

5) Cost-Effective Consumable Design

As a replaceable chamber consumable, this part:

● Protects expensive chamber hardware

● Simplifies maintenance cycles

● Lowers total cost of ownership (TCO)
