The name · 이름의 의미

One name, three roles.

“Haedosa” carries three layered meanings — expert, master, and navigator — that together describe how we work.

Solution Expert

Hae · 解

An expert who analyzes complex problems and proposes the solution.

道士
Master · Guide

Dosa · 道士 / 導師

A master who leads technical direction with deep insight and experience.

海圖士
Navigator

Haedosa · 海圖士

A navigator who explores unknown technical territory and charts new routes.

Core Capabilities · 핵심 역량

Four disciplines, one team.

We can build the entire path ourselves — read measurement data, interpret it with physics models, process it at speed, and judge it with AI. Having all four under one roof is Haedosa's strength.

Physics Simulation

RCWA / FMM

In-house optical analysis engine and first-principles computation for nanostructure spectra and inverse recovery.

High-Performance Computing

CUDA / GPU

GPU acceleration, streaming pipelines, and partition-based parallelism for real-time processing of massive inspection data.

Industrial Software

Full stack · field

High-precision, high-performance software engineered for field deployment — inspection compute optimization and takt-time tuning.

Industrial AI

Classify · detect · VM

Context-based multi-class classification, diffusion-model anomaly detection, and virtual metrology.

Measurement Physics analysis Fast processing AI judgment Result report
Technical Vision · OCD에서 얻은 세 축

Three axes, learned from OCD.

OCD demands accurate physics, fast large-scale computation, and precise measurement-to-inverse recovery at once. From that origin, our technology evolved into three axes — and the same loop now extends to other metrology & inspection problems.

01

Principle

원리

In-house physics simulation for structure analysis, model fitting, and virtual training-data generation.

02

Computation

계산

Multicore parallelism and GPU acceleration that make large-scale simulation, image inspection, and ML feasible.

03

AI

학습

Specialized learning & inference — images, signals/spectra, numerical AI, and in-context inference — on advanced in-house engines.

measure → simulate → learn → measure — a consistent, closed loop
Expansion Approach · 계측·검사 확장

One repeatable improvement loop.

Accurate metrology and simulation stay the reference; repeatedly accumulated data is learned to widen the speed, range, and adaptability of metrology & inspection — one signal modality at a time.

Shapedosa Optical metrology

Design, simulate, fit, generate data, train surrogates, and run Hybrid OCD inverse recovery — all in one desktop workbench, powered by fmmdosa's RCWA/FMM solver.

DeepAOI Image AI

Labeling → training → evaluation → field deployment in one flow. Context-based multi-class classification, SAM auto-labeling, diffusion-model unsupervised anomaly detection.

TSAdosa 3D metrology

GPU-accelerated holotomography volume rendering with cylinder fitting, surface-roughness measurement, and crack-size analysis in one workflow.

stitchdosa Height image stitching

Reconstructs large-area surfaces from height-map tiles — overlap analysis optimization with CPU/GPU-accelerated parallel registration.

VMdosa Virtual metrology

A Large Numerical Model approach: structured numerical tokens + autoregressive, in-context interpretation to estimate quality before physical metrology.

aoidosa High-volume AOI

High-speed optical inspection for wafers and panels — holes/vias, surface defects, cavities, dimensions, bumps — with streaming + ROI parallelism and SPC export.

Codosa Locality-driven AI agent harness

Decomposes development tasks by locality (ELD), recombines code/tests/docs through verified specs (LDD), and runs on-prem so secured data never leaves.

fmmdosa Engine · RCWA/FMM

GPU-accelerated optical simulation: reflection/transmission, ellipsometry Ψ/Δ, Jones, Mueller, and Stokes S0–S7 — feeding spectrum libraries and numerical-AI training.

mldosa Engine · ML/AI (HPC + HPL)

The shared ML engine. High-Precision Learning uses 2nd-order information for fast, accurate convergence on high-oscillation spectra — HPC makes data, HPL trains models.

Optical metrology & simulation

Fourier Modal Method for nanostructure metrology

Rigorous electromagnetic modeling of layered nanostructures — recovering geometry and optical response from measured spectra with production-grade accuracy.

Multilayer hole & taper structures resolved against reference spectra.
Forward solver + inverse fitting across the full wavelength band.
Validated against measurement — model tracks reference within tolerance.
Fourier Modal Method — layered nanostructure metrology
fmmdosa · TwoLayer3PairHole / Tapered — α spectra vs. reference

mldosa · High-Precision Learning — loss convergence to ~1e-6 across runs
ML / AI · HPL

High-Precision Learning for accuracy-critical models

When the answer must be right to many digits, ordinary first-order training isn't enough. We use 2nd-order GPU-accelerated learning that drives loss to the precision floor — fast and reproducibly.

Loss driven toward 1e-6 and below within seconds.
Stable convergence on high-oscillation spectra & narrow responses.
HPC makes the data; HPL trains the model — one consistent flow.
