Please read the special BEAMER manual for a more advanced description of the BEAMER program.


The gds-file is converted to a v30-file by using the programme BEAMER. Please read the special BEAMER manual for a more advanced description of the BEAMER program.


The gds-file is transferred to the folder 'C:\1 gds files\name\date’ on DCH1350. If your v30-file is heavy, you can use DCH1352 instead; this computer is reached via DCH1350 by a remote desktop connection. On DCH1352, put the gds-file in the folder ‘D:\1 gds files\name\date’.


# Open BEAMER.
# Drag the ‘Import’-module to the top-right window of Layout Beamer, open the gds-file to convert
# If the pattern has abutting polygons and even overlapping polygons which lead to double exposure, incorrect simulations etc., this can be fixed by running a ‘Heal’ program; drag the ‘HEAL’-module on top of the gds-file
# Drag the ‘Export’-module on top of the gds-file, export to the location ‘C:\1 gds files\name\date’. Export in JEOL52-format and change field-size to 1000µm x 1000 µm (under 'Advanced’). Click RUN on the Export-icon to execute the whole procedure


This computer also has L-edit installed if last-minute changes to the pattern are needed. The gds-file should then be converted to a v30-file by using the programme BEAMER. There is an elaborated BEAMER software manual available from LabManager (under Technical Documents).


 
The gds-file is now converted to v30-format. In order to check the layout pattern double-click on the v30-module and and a VIEW LAYOUT window will open.
