Non-Disclosure Agreement (NDA)

Note: An NDA is optional. CORNERSTONE does not require an NDA to be signed.

If you intend to submit commercially sensitive designs to CORNERSTONE then both parties are required to sign an NDA. This MUST be stated at the Expression of Interest (EoI) stage, at least 6 weeks before the mask submission deadline, so that the necessary procedures can be initiated. For an expedited process, it is essential that the NDA is accepted in its current form, which you can download below.

If any changes are required, we cannot guarantee that they will be complete before the mask submission deadline.

There are no deadlines for completion of the NDA (if applicable) for bespoke fabrication batches.

Terms & Conditions

Note: All CORNERSTONE partners MUST agree to the Terms & Conditions when submitting a mask design.
