Capabilities

What we can do

A micro- and nano-fabrication toolset, from patterning and etching to packaging and measurement, in one place in the North East.

The tools are in the facility’s toolset and are being recommissioned. Access arrangements and processes are being confirmed by Newcastle University.

Process areas

The steps to make a micro-device, under one roof

Grouped by what each part of the toolset is for. Lithography takes 3-inch wafers on the contact aligner and up to 6-inch wafers on the maskless writer; for other steps, tell us your wafer size and we will confirm it.

Lithography

Pattern features onto wafers, from a design file or a mask.

  • Maskless direct-write lithography on wafers up to 6 inch, with features down to about 1.1 µm
  • Mask-based UV contact lithography on 3-inch wafers
  • Patterning for electrodes, masters and device layers

Dry etch

Etch precise structures into silicon, oxides and thin films.

  • Deep reactive-ion etching (DRIE) of silicon for channels, cavities and deep features
  • Oxide and dielectric etch
  • Reactive-ion and ICP plasma etch for semiconductor and thin-film layers
  • Plasma ashing for descum and oxygen surface treatment

Thin-film deposition

Add metal, functional and protective films.

  • RF and DC magnetron sputtering, including high-field magnetrons for ferroelectric films
  • Electron-beam and thermal evaporation of metals for contacts and electrodes
  • Conformal, biocompatible parylene coating

Thermal processing

Grow, deposit and anneal films at temperature.

  • Furnaces for oxidation, nitridation and polysilicon
  • Plasma-enhanced CVD of oxides and nitrides
  • Rapid thermal processing to 1000 °C
  • Vacuum annealing to 700 °C

Wet processing

Clean, etch and release at dedicated wet benches.

  • Solvent, acid and base benches
  • KOH silicon etch
  • HF benches

Polymers and microfluidics

Build soft-material and fluidic devices.

  • Photolithographic masters, such as SU-8, for PDMS moulding
  • PDMS mixing, and dispensing of silicones and liquids
  • UV epoxy curing and parylene coating
  • Contact-angle measurement of surface wetting

Dicing and packaging

Turn wafers into parts you can connect and test.

  • Wafer dicing
  • Ball, wedge and gold bump wire bonding
  • Bond strength pull testing
  • Sub-micron die placement

Metrology

See and measure what you have made.

  • In the facility: SEM, AFM and X-ray diffraction
  • Stylus profilometry and thin-film thickness measurement
  • On the Newcastle University campus: optical profiling, higher-specification SEM, EDX, XPS and TEM

Typical outcomes

What a project could leave you with

The kinds of results the facility is being set up to support. What is possible for your project depends on the process, and we will talk it through with you first.

  1. A first working prototype

    A chip or device you can test, demonstrate and learn from.

  2. A process recipe you can transfer

    Documented steps a foundry or production partner can pick up.

  3. A short pilot batch

    A small run of devices for trials, field tests or samples.

  4. Characterisation data

    SEM and AFM images, film thicknesses and surface data to guide design decisions.

  5. Packaged parts to test

    Diced, placed and wire-bonded dies, ready to connect to your test set-up.

If a step sits outside the toolset, we can talk about trusted partners for glass laser processing and precision CNC micro-machining.
