Pattern generator - DWL 66fs Laser Lithography System
Description The mask writing process with DWL 66fs is achieved through the help of a 405-nm Diode laser.DWL 66fs has 2 write heads of 2 and 10 mm, which ensure a maximum resolution of 0,6 µm respectively 3 µm. The mask file format can be in any of the following extensions: DXF, HPGL, Gerber, GDSII or CIF. Writing facility: on mask (with dimensions ranging between 2,5” and 6”) and on plates (with the diameter bigger or equal to 3”)

Application It can be used for mask making or direct exposure on basically any flat material coated with photoresist. Numerous optional features increase the flexibility and make the system suitable for more applications. And if one of your applications requires a special technology, it can most likely be implemented in the DWL 66FS. |

| - This strongly depends on the masks design and the number of masks requested. From our experience in the last year, we have had an average time of about 2 day after the file is accepted, for dimensions bigger than 3 microns and for dimensions between 1-3 microns it strongly depends of the area to expose and it can be about 6 days. Check with the process engineer in regards to the status of the mask queue and the status of the machine.
For masks that are to be shipped by courier, add at least one more business day. The extra time depends on the shipping carrier. - Cost of Mask: to estimate the cost of the mask, the extents of the pattern have to be specified. The extents are the X and Y dimensions of a rectangle that completely covers all the features of the pattern of the mask. Once you have these dimensions, you can contact the process engineer to obtain the cost of the mask: - Critical Dimensions Specifications: The current spec for the critical dimensions is 2 micron with a 0.2 micron tolerance. The CD can be pushed down to 2 micron, but results depend strongly on the layout and are not guaranteed. - Available Plates: We currently have Chrome Soda Lime Masks and the available sizes are 4inch, 5inch, and 6inch (maximum 6 inch, only on command). We DO NOT supply Iron Oxide masks and there is currently no plan to have that kind of masks available in the near future. If you need Iron Oxide, please contact other mask shops. - Mask File Acceptable Formats: Either CIF of GDSII formats are preferred. DXF is also acceptable, but please verify the pattern with the process engineer before submitting it as we have found incompatibility problems. ****************************************************************** |
