Chemical vapor deposition (CVD) furnaces play a critical role in the semiconductor industry, enabling precise thin-film deposition for advanced device fabrication. These systems deposit materials like silicon dioxide, silicon nitride, and polysilicon—essential layers for integrated circuits. Beyond basic deposition, CVD furnaces support high-temperature processes (up to 1900°C) for specialized materials, offer programmable automation for reproducibility, and facilitate research on next-generation semiconductors. Their versatility extends to synthesizing graphene, protective coatings, and composite materials, making them indispensable for both production and R&D.
