2025 MPW Delivery Timelines
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- Post deadline design rule checking (DRC) is withdrawn.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.
