SiC Processing Dust Collection for Semiconductor Workshop: SICC New Processing Facility Case Study<\/h2>\n\n\n\n

Project Background: SiC Wafer Processing Dust Collection in Semiconductor Manufacturing<\/h2>\n\n\n\n

SiC Processing Dust Collection. Shandong Tianyue Advanced Technology Co., Ltd. (SICC) ranks among the global top three silicon carbide substrate manufacturers. Therefore, when SICC built a new processing workshop in Jinan, dust purification became a critical priority. Specifically, the project addressed airborne contamination across slicing, grinding, polishing, and cleaning operations. Moreover, SiC dust poses unique challenges due to its extreme hardness and ultra-fine particle size.<\/p>\n\n\n\n

Silicon carbide substrate manufacturing generates significant airborne particulates. Consequently, these particles threaten both product yield and worker health. Furthermore, SiC dust reaches Mohs hardness 9.5, which damages precision equipment surfaces. However, standard dust collectors cannot effectively capture sub-micron SiC particles. Therefore, a specialized SiC wafer processing dust collection system was essential.<\/p>\n\n\n\n

Why SiC Substrate Manufacturing Demands Specialized Dust Purification<\/h2>\n\n\n\n

Silicon carbide substrate production follows a rigorous process chain. Specifically, the workflow includes SiC powder synthesis, crystal growth via PVT method, wire slicing, lapping, CMP polishing, and final cleaning. Meanwhile, each processing stage generates distinct dust profiles.<\/p>\n\n\n\n

Ultra-Fine Particle Challenge in SiC Wafer Processing Dust Collection<\/h3>\n\n\n\n

SiC processing dust presents three critical challenges. First, particle size distribution ranges from 0.1 to 10 micrometers. Moreover, the 0.5 to 1 micrometer fraction dominates the output. Consequently, conventional filters with micron-level ratings cannot achieve sufficient capture rates.<\/p>\n\n\n\n

Second, SiC particles carry extreme hardness. Specifically, at Mohs 9.5, silicon carbide ranks just below diamond. Therefore, airborne SiC dust abrades precision equipment surfaces, guide rails, and optical components. Furthermore, this abrasion degrades wafer processing accuracy over time.<\/p>\n\n\n\n

Third, SiC processing generates mixed pollutants. Wire cutting produces oil-laden fumes alongside fine dust. Grinding and polishing create slurry-based wet particulates. Meanwhile, crystal growth furnaces release carbon particles and silicon oxide microspheres. Thus, a single-stage filter cannot address all contaminant types effectively.<\/p>\n\n\n\n

Semiconductor Cleanroom Standards for Silicon Carbide Dust Purification<\/h3>\n\n\n\n

Semiconductor manufacturing imposes strict air quality requirements. Specifically, particulate contamination directly reduces wafer yield. Moreover, even microscopic dust landing on a substrate surface causes circuit defects in downstream epitaxy and device fabrication. Therefore, the dust collection system must achieve filtration efficiency above 99.97% for particles at 0.3 micrometers and above.<\/p>\n\n\n\n

In addition, China’s electronic industry standard GB 39731-2020 mandates specific emission limits for semiconductor facilities. Furthermore, GB 16297-1996 sets comprehensive air pollutant discharge standards. Consequently, the purification system must satisfy both occupational health and environmental compliance simultaneously.<\/p>\n\n\n\n

System Design: Multi-Stage SiC Dust Purification for New Processing Workshop<\/h2>\n\n\n\n

High Vacuum Centralized Dust Collection Architecture<\/h3>\n\n\n\n

The SICC new workshop required a centralized high vacuum dust collection system. Therefore, Meilan designed a multi-point extraction network covering all dust-generating processes. Specifically, the system captures contaminants at each source point through dedicated suction hoods and enclosed process chambers.<\/p>\n\n\n\n

The centralized architecture offers several advantages. First, a single high-power host unit replaces multiple standalone collectors, therefore reducing equipment footprint. Second, consolidated filtration simplifies maintenance and filter replacement. Furthermore, the system enables organized emission through a dedicated stack. As a result, compliance monitoring becomes straightforward.<\/p>\n\n\n\n

Source Capture Strategy for Semiconductor Workshop Dust Extraction<\/h3>\n\n\n\n

Effective SiC dust control begins at the source. Therefore, each processing station features purpose-built capture mechanisms:<\/p>\n\n\n\n
