Vertical Silicon Boat

Semicorex Vertical Silicon Boat is a crucial component, specifically in high-temperature environments for wafer processing. Designed to hold silicon wafers vertically during heat treatment and diffusion processes, this product ensures optimal thermal uniformity, precise handling, and superior stability, which are vital for achieving consistent wafer quality.

Key Applications in Semiconductor Processes

The Vertical Silicon Boat is primarily utilized in processes such as oxidation, annealing, diffusion, and chemical vapor deposition (CVD). During these steps, the uniform exposure of silicon wafers to heat and reactive gases is crucial for forming critical layers and structures on the wafer surface. By securely holding the wafers in a vertical orientation, the silicon boat facilitates even gas flow and temperature distribution across all wafers, reducing the risk of defects and improving overall yield.

Oxidation and Diffusion: The Vertical Silicon Boat plays a pivotal role in high-temperature oxidation and diffusion processes. These steps require precise control over gas flow and temperature to form oxide layers and dope wafers with impurities for electrical conductivity. The boat’s design ensures uniform exposure and minimizes contamination risks.

Annealing: During annealing processes, wafers are subjected to controlled heating and cooling cycles to relieve stress, repair damage, or activate dopants. The silicon boat’s thermal stability and excellent mechanical strength help maintain wafer integrity during these demanding cycles.

CVD and ALD Processes: For processes like chemical vapor deposition (CVD) and atomic layer deposition (ALD), which involve the formation of thin films on the wafer surface, the Vertical Silicon Boat provides a stable platform for consistent material deposition. Its high-purity composition minimizes particle contamination, essential for achieving defect-free layers.
