IC Fabrication Using Electron-Beam Technology.
Abstract
The technical and economic impact of electron-beam direct slice printing will be demonstrated on 256-bit bipolar RAMs. All electron-beam tapes necessary for fabricating the 256-bit bipolar RAMs have been generated. Advanced software techniques such as geometry sizing, sorting and increment/decrement were used. E-beam processes have been developed for all lithographic steps on the 256-bit bipolar RAMs. Because of the pattern distortion at epitaxial growth, the original alignment marker system was modified. Several lots using this new alignment marker system are in process. The design of the Automatic Slice Loader is complete. (Author)
