2024 MPW Pricing
As a trial in 2024, we will offer priority and standard delivery timeframes for MPW runs.
When opting for our priority service, the following changes are made to our standard service;
- We simplify batch specific quality controls such as CD-SEM and rely on our routine monthly quality control and the inherent reliability of the lithography process.
- When using our suppliers’ services for reticle procurement and implantation we pay for the expedited options
- We pay our dedicated team to perform out of hours work with priority access to cleanroom tools.
- Post deadline design rule checking (DRC) is withdrawn. Users must submit DRC clear design file on submission. We will offer extra support in the lead up to the deadline to our priority users.
If you would like to discuss our priority service in more detail then we would be happy to speak to you over a video call.

Staff and students employed at UK Universities
In previous years, we have provided free access to particular MPW batches for staff and students employed at UK Universities, leveraging EPSRC funding under the CORNERSTONE & CORNERSTONE 2 projects. Whilst we have not yet finalised the details of our CORNERSTONE 2.5 funded 2024 MPW batches yet, we will be updating the website with information on which batches will be free/subsidised for staff and students at UK Universities as soon as possible.
