Semiconductor cleanroom — operator in bunny suit, sensor network glow
Moseley Semiconductor Platform

See every molecule in the bay.

MSCC streams contamination risk across every dock, tool and load port — flagging AMC (Airborne Molecular Contamination) excursions before they touch the wafer.

01 · The platform

One platform. Every chamber.

Our e-canisters mount inside FOUPs (Front-Opening Unified Pods), EFEMs (Equipment Front-End Modules), load ports and process chambers. A MOF-coated FBAR (Film Bulk Acoustic Resonator) array — 16 sensors arranged as four sensors per channel across four channels — detects HF, ammonia, NMP and organic outgassing in parts-per-billion. A TinyML (on-device machine learning) model on the canister's PCBA (printed-circuit board assembly), co-located with the sensor array, classifies risk in real time and pushes it straight to the bay view above so excursions are caught before they reach the wafer.

01

ppb-level AMC

HF, NH₃, NMP, organic outgassing — caught before defects appear.

02

Per-tool resolution

One canister per dock, FOUP or load port. Pinpoints the source, not the room.

03

Real-time risk score

Low / medium / high per asset, refreshed every second on the bay view.

04

Drop-in install

Battery + PV powered, BLE (Bluetooth Low Energy) backhaul. No fab-network changes required.

02 · How it works

From molecule to mitigation in under a second.

  1. 01

    Sense

    The E-Array — a metal-cystine coordination complex sensor array inside the E-Aegis host platform — captures target molecules at ppb concentrations. Multiple metal centres, multiple sensing elements per metal, one reading per element per second.

  2. 02

    Classify

    E-Sentinel — the Moseley on-device ML model running on the host MCU (microcontroller unit) of the E-Aegis — fingerprints the full multi-channel response from the E-Array, separating HF from NH₃, NMP from siloxane, signal from drift.

  3. 03

    Score

    A per-asset risk level (low / medium / high) is published over BLE — every dock, FOUP, load port and tool gets its own tile on the bay view.

  4. 04

    Act

    Excursions trigger getter activation, FOUP purge, or operator alert via the existing fab MES. No new pipes, no new network.

03 · What it catches

The molecules that destroy yield.

Even in an ISO Class 3 cleanroom, ppb-level airborne molecular contamination from process chemistry, outgassing polymers and HVAC ingress can pit photoresist, corrode interconnects and tank yield. Here are the targets.

HF

Hydrogen fluoride

Acidic AMC — pits oxide and metal layers.

NH3

Ammonia

Basic AMC — destroys DUV photoresist sensitivity (T-topping).

NMP

N-methyl-pyrrolidone

Solvent outgassing from photoresist strippers.

H2SO4

Sulfuric acid mist

From wet-bench piranha cleans — corrodes metallurgy.

HCl

Hydrogen chloride

Etch by-product — surface haze and dopant drift.

VOC

Organic outgassing

Siloxanes, phthalates — surface molecular condensation on optics.
