Common questions about the SemiFlows platform
SemiFlows is an AI-powered semiconductor process knowledge platform that provides complete, step-by-step process flows from 40nm to 7nm, covering both logic chips and CMOS image sensors. It integrates extensive research papers, patents, and authoritative textbooks to deliver in-depth rationale analysis with citation tracing for each process step. The 40nm BSI CIS flow is entirely free.
SemiFlows currently covers four process flows: 40nm BSI CMOS Image Sensor (417 steps, free), 28nm Planar (341 steps), 14nm FinFET (353 steps), and 7nm FinFET (716 steps). Together, these flows provide over 1,800 detailed process steps spanning both logic chip and image sensor fabrication.
Unlike general AI assistants, SemiFlows is purpose-built for semiconductor process engineering. Every answer is grounded in curated academic papers, patents, and textbooks — not general internet knowledge. The platform provides citation-backed explanations with traceable references, structured process flows, and domain-specific context that general AI tools cannot match.
SemiFlows provides physics and chemistry principles behind each process step, mechanism explanations (why a process works), integration rationale (why steps are ordered a certain way), and risk analysis. All content focuses on fundamental principles — not specific manufacturing recipes, equipment parameters, or vendor details.
Yes. SemiFlows supports both English and Chinese (中文). Users can switch languages at any time using the language toggle. The AI chat assistant also responds in the user's selected language.
