The Cleanroom at LCN on the Bloomsbury site has 255 square metres of ISO 14644-1 Class 6 (Class 1000) cleanroom housing most of our equipment for Plasma etch, Photolithography, Wet Chemical, Metallisation, Furnace, Characterisation and Electron Beam Lithography processes. There are separate spaces which house three Focused Ion Beam (FIB) tools, and a Back-End Laboratory for processes such as sawing, scribing & wire bonding.

To see the full list of Equipment on offer look further on these Equipment pages.

The Cleanroom is an Open Access facility, offering equipment and services to outside academic and industrial users in addition to LCN researchers. We welcome users who will enrol and train to operate the equipment themselves. See Enrolment and Training details.

The cleanroom equipment usage is controlled by the PPMS . See

This is accessible to people with a UCL login.


Cleanroom Use Under COVID

The rules change in line with LCN and UCL’s codes of Practice as the COVID situation evolves.

Additional Restrictions applicable from 6 Jan 2021, these overide statements below

There will be limited availability of technical staff, and there will be no guarantee of First Aider presence in LCN. With the LCN requirement to only do activities consistent with 2m distancing, I have decided to impose the following restrictions on cleanroom use until further notice .

1) No Equipment Training will be available until further notice, but Online Inductions will continue as timetabled.

2) Only users with card access to the labs can use the facilities:

a)Those with 24/7 or out of hours card access can use the facilities between 08:00 and 20:00 under the out of hours rules

b)Those with M-F card access can use the facilities, but only if they are confident in the equipment use and operation.  You should also ensure that someone else is in the cleanroom at the same time

c)Those without card access to the cleanroom labs, cannot use the facilities at this time.

3) The wet benches may only be used between 10:00 to 16:00 in the main cleanroom, and there must be another person present in the Cleanroom to act as a buddy and render assistance. No wet bench use is permitted in back end lab at all.

The technical team will be available to answer your queries by email and TEAMS, and we will endeavour to have one person in the building between 10:00 and 16:00 M-F.
