Three Pillars, One Multi-Scale Thermal OS

From the silicon surface to the central chiller plant, patent-pending pillars couple into a single closed loop — the "Wafer-to-Chiller" thermal operating system.

Pillar 1

NanoTwin™

Patent Pending Micro / Nano-Scale Digital Twin

A physics-guided (PGML) digital twin that replaces slow Finite Element Analysis with Fourier Neural Operators — delivering single-state queries in under 5 ms and the full 3-D junction and wafer temperature field in 28 ms.

  • Full 3-D wafer temperature field in 28 ms; single-state queries <5 ms
  • Virtual sensing inside vacuum, RF-plasma & high-TDP test
  • Air-gapped edge appliance, fab-grade zero-trust security
Pillar 2

PlantTwin™

Infrastructure Scale Macro / Facility Digital Twin

A facility-scale infrastructure digital twin that models the full cooling network and captures the tool-to-facility dynamic interactions and load rejection that reactive controls miss.

  • Dry coolers, chillers, heat exchangers & hydraulic loops
  • Captures tool-to-facility dynamics & load rejection
  • 1–24 hr forward horizon with weather & tariff inputs
Pillar 3

Modular MPC

Patent Pending Closed-Loop Control Engine

A constrained convex optimization engine pairing fast edge MPC with supervisory plant MPC, under a hardware-enforced advisory-only fail-safe that keeps native controllers in full safety authority.

  • Fast edge MPC (tool heaters/chucks) + supervisory plant MPC
  • Factory-calibrated Unit Model Certificates — commissioning in hours
  • Hardware-enforced fail-safe — zero freezing & downtime risk

Coupled as One Loop: "Wafer-to-Chiller"

The defensible advantage is the coupling. A heat pulse detected at the silicon surface is propagated, forecast, and acted on across the full physical continuum — seconds before the thermal wave arrives.

NanoTwin™
Detects the micro-scale heat surge in <5ms
PlantTwin™
Forecasts facility propagation & load rejection
Modular MPC
Acts proactively across tool & plant setpoints

Result: wafer uniformity clamped within ±0.2°C and sub-fab PCW header stability held within ±0.1°C.

Validation

Digital Twin vs. Finite Element Analysis

A side-by-side solve-speed race on a wafer prober. The NanoTwin™ digital twin computes the full 3-D temperature field in 28 ms while FEA takes minutes.

Built for Industries Where Precision is Non-Negotiable

MacroThermo's near-term focus is semiconductor manufacturing, where thermal precision directly drives yield. The same technology extends to medical devices, high-power laser cooling, and other precision cooling applications.

Semiconductor Manufacturing

Enable next-node yield with thermal stability for lithography, etch, deposition, and test. Our systems integrate seamlessly into fab tools and subfab infrastructure.

Medical, High-Power Laser & Other Precision Cooling

Extending the same technology to medical devices (MRI, CT, IVD analyzers), high-power laser cooling, and other precision cooling applications. Designed for reliability, serviceability, and regulatory compliance.

Our Mission

To build complete thermal systems — hardware and software engineered together — for mission-critical manufacturing. Our edge appliances, control gateways, and factory-calibrated equipment models run on site, optimizing precision, energy efficiency, and yield from the wafer surface to the central chiller plant.

Our Story

Heat is continuous, but its control is not. Inside the tool, slow simulations force reactive control loops; in the sub-fab, chiller plants run on static schedules. When a heat pulse leaves the chamber, the facility reacts minutes too late — and the swing feeds back into the process.

CJ Tang founded MacroThermo in 2026 in the Capital Region of New York, home of the Albany NanoTech Complex, to close that gap. NanoTwin™, PlantTwin™, and Modular MPC couple the tool and the facility into one closed loop.
