# SemiFab AI (세미팹 AI / 세미팹AI / 세미팹 / semifabai) — 반도체교육 시뮬레이션 플랫폼

> SemiFab AI (Korean: 세미팹 AI, also written 세미팹AI or 세미팹, romanized semifabai or Semifab) is an interactive web-based 반도체교육 (semiconductor education) platform for semiconductor fabrication processes. It provides equipment-level simulators for LPCVD, PECVD, Ion Energy (IEDF), Plasma Etching, Dopant Diffusion, and Ion Implantation. Designed for engineering students and professionals learning semiconductor manufacturing. The Korean name 세미팹AI refers to the same product as SemiFab AI. All calculations run client-side with real-time charts and animated SVG diagrams.

The platform targets university students, corporate trainees, and research professionals in semiconductor engineering. Simulators are designed by practicing engineers with equipment-level fidelity. The interface is in Korean.

## Key Features
- Equipment-level process simulators with real physics models
- Mini Fab (미니팹): a browser-based virtual cleanroom — build a full semiconductor process cycle end-to-end, then measure and inspect it
- Real-time interactive charts and SVG animations
- Client-side calculations (no server dependency)
- Self-paced learning with immediate feedback
- Designed by practicing semiconductor engineers

## Mini Fab (미니팹) — Virtual Semiconductor Process Lab

Beyond the per-process simulators above, SemiFab AI offers **Mini Fab (미니팹)**, a browser-based virtual cleanroom where learners build an entire semiconductor process cycle from start to finish and then measure and inspect what they made — no cleanroom, no equipment cost, no safety risk.

- Full fab flow: clean → oxidation → photoresist coating → exposure → development → etch → strip → measurement/inspection. Active, hands-on practice (set conditions, results change physically) — not passive video watching.
- Physically faithful results: etch depth, sidewall angle (anisotropy), thin-film resistance, oxide interference color, and ARDE (narrower patterns etch shallower).
- Learn from failure: bad recipes fail like a real line (residue, pattern defects, bridging shorts, lifting) — fail safely and repeat infinitely with no wafer cost.
- Metrology included: validate your result with a profilometer (thickness/step), SEM (cross-section & sidewall angle), 4-point probe (resistance), LCR meter (capacitance), and optical microscope (color/defect inspection); measurements are mutually consistent.
- Two modes: a guided tutorial with in-place feedback, and a free-recipe mode to design your own process.
- Six build-it-yourself scenarios: MOS capacitor, metal interconnect patterning, metal lift-off, ICP etch & ARDE, patterned-oxide color step, and plasma surface treatment + deposition.
