    R extraction for the diode array

    andrewng

      Dear All,

       

      I meet a case that when I extract a N-type diode array (N+ diffusion on P-well) and found the resistance value of P-well terminal is always lower than I expected.

      The case is I used a 10000um long path to parallel the N-type diode array with same terminal.

      I expected the extracted resistance for P-well terminal is about 150ohm.

      However, the extracted point of this terminal is alway on the middle of the whole P-well.

       

      Is there someone could give me advise how to extract resistance which for the diode terminals?
