Making Semiconductor Process Knowledge Accessible
Semiconductor process knowledge is scattered across thousands of papers, patents, and textbooks. Engineers often spend years building systematic process understanding. SemiFlows integrates this fragmented knowledge into a structured, searchable, citation-backed process knowledge base — accelerating learning and decision-making for every engineer.

About the Founder
SemiFlows is independently built by Joseph Zheng, a semiconductor process engineer with 15+ years of hands-on process development experience. From Planar MOSFET through FinFET, Joseph has worked across multiple technology generations in process integration roles, and understands firsthand the pain of searching through vast literature for critical information, and the long journey of building systematic understanding from fragmented knowledge. SemiFlows was created to solve exactly this problem.
Business Model
SemiFlows uses a transparent, sustainable two-tier pricing model: one-time purchase of process flow content per technology node (lifetime access), plus an optional AI deep analysis subscription (monthly/annual). Free users can try basic AI Q&A and flow previews.
