SiC Ceramic Paddles

As semiconductor manufacturing continues to demand tighter process control and higher production yields, wafer handling components must deliver exceptional dimensional stability, contamination resistance, and mechanical strength under elevated temperatures. SiC Ceramic Paddles are specially engineered cantilever wafer carriers designed to transport and support wafers throughout high-temperature furnace processes while maintaining outstanding structural integrity.

Manufactured from high-purity silicon carbide (SiC) ceramic, Semicorex SiC Ceramic Paddles are widely used in diffusion, oxidation, annealing, LPCVD, and other thermal processing equipment. Their lightweight yet rigid cantilever structure minimizes wafer vibration during loading and unloading, ensuring accurate positioning and safe transfer inside furnace systems.

Designed for long service life and consistent performance, these paddles help semiconductor manufacturers improve process stability, reduce contamination risks, and increase equipment productivity.

Purpose-Built for High-Temperature Furnace Operations

Unlike conventional wafer handling tools, SiC Ceramic Paddles are designed to operate directly inside furnace chambers where temperatures may exceed 1,000°C for extended periods.

Their cantilever configuration enables operators or automated handling systems to insert and remove wafer boats without disturbing the carefully controlled thermal environment. Throughout repeated heating and cooling cycles, the paddles maintain their mechanical strength and dimensional accuracy, allowing wafers to remain securely supported during transport.

Typical furnace applications include:

* Silicon wafer diffusion

* Thermal oxidation

* Annealing processes

* LPCVD processing

* Semiconductor heat treatment

* Research and pilot production lines

Their stable performance makes them indispensable in both semiconductor fabrication facilities and photovoltaic manufacturing.
