WieWeb software’s main product is the layout editor CleWin. CleWin is a layout editor we designed in cooperation with the MESA+ Research Institute at the University of Twente and Deltamask , a mask making company. Since we started with the development of CleWin, more than 20 years ago, the product has evolved from a simple editor to a powerful mask design tool. The product has been very successful over the years and is used worldwide in 35 countries at hundreds of companies and universities.
Ten years ago CleWin version 5 was released and, after many minor updates, version 6 was released on November 15, 2022. For companies with a valid update and support subscription the upgrade to version 6 is included in the subscription. For universities, all CleWin 5 licenses purchased after July 1st, 2022 include the upgrade. CleWin 6 can be downloaded from the CleWin 6 Download page .
CleWin runs on a PC with Windows 10 or higher. It is compatible with other layout software since it uses the standard CIF, GDS-II and OASIS file formats . Furthermore, CleWin can read and write the AutoCAD DXF format. High resolution (Encapsulated) PostScript is available as output format. Bitmap files can be easily imported using the bitmap import utility .
