Capabilities

Parent Facility

Electron-beam lithography

Service

Provides services for the fabrication of devices by electron beam lithography, patterning silicon wafers with feature sizes ranging from hundreds of micrometers down to 8nm.

Nanofabrication

Photolithography

Service

A photolithography room with manual spin coaters and manual mask aligners for chips and up to 3ƒ?ü wafers, utilising a range of resists and manual development processes.

Core Nanofabrication

Wet processing

Service

Dedicated laminar flow wet benches for work with solvents and acids. Wet etching and cleaning of samples, ranging in size from chips upto 4ƒ?ü wafers. This includes using hydrofluoric acid (HF) and piranha for etching/cleaning.

Core Nanofabrication

Dry etching

Service

We have a small suite of dry etch tools for both reactive ion etching (RIE) and inductively coupled plasma (ICP) etching. These tools have a range of process gases, with dedicated tools for Chlorine-based etching of III-V semiconductors and Fluorine-based etching of dielectrics.

Core Nanofabrication

Deposition of metals

Service

A small suite of thermal and e-beam evaporators, for the depositions of single films or multilayer stacks. Typically the available metals are grouped into ohmic material or gates material (see below). The evaporators can accommodate chips upto 4ƒ?ü wafers with a range of uniformity (see below).

Core Nanofabrication

Dielectric deposition

Service

Including plasma-enhanced chemical vapor deposition (PECVD) of silicon nitride (SiNx) and silicon oxide (SiOx), thermal atomic layer deposition (ALD) and e-beam evaporation of AlOx.

Core Nanofabrication

Metrology, inspection and testing

Service

Electron Beam Lithography

III-V (Arsenides) Growth

Service

III-V (Arsinides) work is undertaken on our Veeco GEN III and Veeco modGEN II growth chambers on up to 3ƒ? substrates; the GEN III is UHV connected to a dedicated Veeco 620 system which allows for in-situ atomic hydrogen surface cleaning/preparation and secondary ion mass spectrometry (SIMS) characterisation.

Growth

Topological Materials Growth

Service

The Topological Materials chamber is a PREVAC MBE dual chamber design, funded by the Royce Institute, that supports growth on up to 2ƒ? substrates. The main chamber allows epitaxial growth of Topological and related materials and is UHV connected to a secondary chamber that currently allows deposition of a range of metals.
