SiC Wafer Carrier

Semicorex SiC Wafer Carrier is a specialized high-purity fixture designed to support and transport multiple semiconductor wafers through extreme thermal and chemical processing environments. Semicorex provides these next-generation wafer boats using advanced 3D printing technology, ensuring unparalleled geometric precision and material purity for the most demanding wafer fabrication workflows.

Redefining Precision: 3D-Printed High-Purity SiC

Traditional manufacturing methods for wafer carriers, such as machining or assembly from multiple parts, often face limitations in geometric complexity and joint integrity. By utilizing additive manufacturing (3D printing), Semicorex produces SiC Wafer Carriers that offer significant technical advantages:

Monolithic Structural Integrity: 3D printing allows for the creation of a seamless, single-piece structure. This eliminates the weak points associated with traditional bonding or welding, significantly reducing the risk of structural failure or particle shedding during high-temperature cycles.

Complex Internal Geometries: Advanced 3D printing enables optimized slot designs and gas flow channels that are impossible to achieve via traditional CNC machining. This enhances process gas uniformity across the wafer surface, directly improving batch consistency.

Material Efficiency and High Purity: Our process uses high-purity SiC powder, resulting in a carrier with minimal trace metallic impurities. This is critical for preventing cross-contamination in sensitive diffusion, oxidation, and LPCVD (Low Pressure Chemical Vapor Deposition) processes.

Performance Excellence in Extreme Environments

Semicorex SiC Wafer Carriers are engineered to thrive where quartz and other ceramics fail. The inherent properties of high-purity silicon carbide provide a robust foundation for modern semiconductor fab operations:

1. Superior Thermal Stability

Silicon Carbide maintains exceptional mechanical strength at temperatures exceeding 1,350°C. Its low coefficient of thermal expansion (CTE) ensures that the carrier slots remain perfectly aligned even during rapid heating and cooling phases, preventing wafer "walking" or pinching that can lead to costly breakage.

2. Universal Chemical Resistance

From aggressive plasma etching to high-temperature acid baths, our SiC carriers are virtually inert. They resist erosion from fluorinated gases and concentrated acids, ensuring that the dimensions of the wafer slots remain constant over hundreds of cycles. This longevity translates to a significantly lower Total Cost of Ownership (TCO) compared to quartz alternatives.

3. High Thermal Conductivity

The high thermal conductivity of SiC ensures that heat is distributed uniformly throughout the carrier and transferred efficiently to the wafers. This minimizes "edge-to-center" temperature gradients, which is essential for achieving uniform film thickness and dopant profiles in batch processing.

Industry Applications

Semicorex SiC Wafer Carriers are the gold standard for high-performance batch processing in:

Diffusion and Oxidation Furnaces: Providing stable support for high-temperature doping.

LPCVD / PECVD: Ensuring uniform film deposition across entire wafer batches.

SiC Epitaxy: Withstanding the extreme temperatures required for wide-bandgap semiconductor growth.

Automated Cleanroom Handling: Designed with precision interfaces for seamless integration with FAB automation.
