Within　the　limit　of　fabricating　techniques,　2000　l/mm　self-standing　transmission　gratings　model　was　designed.　And　by　combining　the　techniques　of　electronic-beam　lithography　and　X-ray　lithography,　the　2000　l/mm　X-ray　self-standing　transmission　gratings　was　fabricated.　Firstly,　the　electronic-beam　lithography　and　micro-electroplating　technology　was　used　to　prepare　a　master　mask　of　gratings　on　polyimide　membrane　substrate.　Then　by　using　X-ray　lithography　and　micro-electroplating,　child　gratings　was　replicated　on　the　master　mask.　And　the　self-standing　graph　was　transferred　to　the　daughter　gratings　via　utraviolet　(U-V)　lithography　and　micro-electroplating.　Finally,　with　the　technology　of　etching　and　inductively　coupled　plasma　(ICP),　the　fabrication　of　X-ray　self-standing　transmission　gratings　was　fulfilled.　From　the　fabrication　results　of　the　gratings,　it　shows　that　bars　smoothness,　the　absent　ratio　and　the　profile　of　the　gratings　are　all　desired.
