Hello folks, I4m starting to use ACES (Anisotropic Etch Simulator) to simulate some structures but I didn4t find a (good) way to generate the masks to use in the simulations. I4m using FreeHand (a vetorial editor) to generate the masks and to export in BMP format, but I4m facing some ems with this procedure (distortion of the dimensions). Someone know some way to use AutoCad or LASI to generate the masks or have used the CIF or GDS formats in ACES simulations? Thanks in advance, Luiz Marangoni UNICAMP - Campinas - Brazil
