The Roles in Semiconductor Manufacturing

In core thermal processing steps of semiconductor manufacturing, such as diffusion furnaces and oxidation furnaces, SiC Cantilever Paddles play an indispensable role. They are critical carriers for precise, efficient, and contamination-free wafer handling and support.

1. Application in Diffusion Furnaces:

Diffusion furnaces are key equipment in semiconductor manufacturing used for doping and forming PN junctions. At high temperatures, impurity atoms diffuse into the wafer, altering its electrical properties.

●Precise Wafer Positioning & Transfer: Thanks to their high rigidity and low thermal expansion, SiC cantilever paddles ensure wafers are precisely carried and delivered to their designated positions within the high-temperature furnace. This prevents wafer slippage or deformation, guaranteeing consistency in the diffused layers.

●Reduced Particle Contamination: In the highly pure environment of diffusion, the extremely low particle shedding rate of SiC paddles is crucial for maintaining product yield. It effectively prevents particle contamination caused by traditional materials, thereby reducing defect generation.

●Extended Equipment Maintenance Cycles: The exceptional high-temperature and corrosion resistance of SiC paddles significantly extends their lifespan in diffusion furnaces, reducing replacement frequency and downtime, which lowers operational costs.

2. Application in Oxidation Furnaces:

Oxidation furnaces are used to grow thin oxide layers on the wafer surface, such as gate oxides or field oxides. These oxide layers are essential for isolating and protecting semiconductor devices.

●Wafer Support Under High-Temperature Stability: The oxidation process typically occurs in high-temperature, oxygen- or steam-rich environments. SiC cantilever paddles can withstand these extreme conditions, stably supporting wafers to ensure uniform oxide layer growth and consistent film thickness.

●Minimized Chemical Reactions & Contamination: SiC is highly inert to oxidizing atmospheres and will not chemically react with furnace gases, thus avoiding the introduction of additional impurities and ensuring the purity and electrical performance of the oxide film.

●Improved Process Repeatability: The excellent thermal shock stability and mechanical strength of SiC paddles guarantee consistent wafer conditions in each oxidation cycle, thereby improving process repeatability and yield.
