Dear all,


I am using the Leica EBL 100 nano writer e beam lithography for my work. But I
am troubled by the preparation of spd files that are needed for the patterns, as
I have to input the coordinates of every point via the text interface. And it is
even troublesome when I am intending to have some curvilinear patterns. Is there
any other approach to generate the spd format files? e.g. some GUI software to
draw the patterns directly and the patterns can be saved as spd files and then
be used for further conversion to EBEAM datas. Anyone can recommend some free
softwares? Thank you in advance!

Regards,
Zhanghua
