MPW 30th Call on 220nm SOI

CORNERSTONE users are invited to submit designs to the thirtieth call with a platform of 220nm SOI (passive devices with heaters).

A process design kit (PDK) is available using Luceda’s IPKISS software, subject to purchasing the appropriate license. To obtain a copy of the software and a license key, please contact Luceda by sending an email to This email address is being protected from spambots. You need JavaScript enabled to view it., specifying that you require a license for CORNERSTONE PDK usage. Of course, the CORNERSTONE PDK is free of charge if you already have a valid IPKISS license. 

Access to this run is charged with the following cost options:

Design Area Cost with heaters Cost without heaters
11.47 mm x 4.9 mm £13,150 £7,100
5.5 mm x 4.9 mm £9,000 £4,750

We are launching a new initiative to encourage our users to include the Engineering and Physical Sciences Research Council (EPSRC) funded CORNERSTONE (EP/L021129/1) or CORNERSTONE 2 (EP/T019697/1) projects in the “Funding” section of relevant journal publications. This is important to us to be able to demonstrate impact from the funding.

Therefore, if you are able to share the digital object identifier (DOI) of three previous published journal papers that reference one of the CORNERSTONE projects, we will give you a 10% discount from the access charge

The sign-up deadline is Friday 9th September 2022. The mask submission deadline is Friday 7th October 2022.

For more information, full design rules and quick reference design rules, please download the CORNERSTONE 28th Call Design Rules documents and the .GDSII template files. 

 In order to help you ensure that you comply with the design rules, you can also download a design rule check (DRC) checklist and if you have access to Tanner L-Edit software, a .tdb version of the template containing a DRC file that you can run to automatically find any design rule violations (note that the automatic DRC will not check all of the design rules, so it remains very important to read the design rules in detail).

For any queries, including questions on bespoke processing i.e. custom etch depths etc., please contact This email address is being protected from spambots. You need JavaScript enabled to view it.
