  • Hi Kari,
     
    Thank you for the reply.How are you doing.
     
    I just gone through the doc, but can you please help me for the following queries
     
    1) My LEF don't contain any bump by default.Is it the case of all libraries? Do the foundry need to support for flip chip? I mean is some kind of IO cell needs to be present in my library for doing a flip chip?
     
    2) can you please give me summarized steps( steps are enough).
     
    3) do the bumps have any DRC rules? I don't see any in my design manual or is it enough to take care of the polygon rules of Metals?
     
    4) Is a bump just a single metal or is it a metal array ? can I place a standard cell or macro below the bumps?
     
    I haven't used this IO type before,If you can help i will be so grateful.
     
     
    can you please tell me the library prerequisite required for flip chip .
     
    Thanks
