Title: POLY1 must be covered by N+ or P+ implant layer @Umc40lp using Calibre Post by Ramakrishna RSSM on May 7th, 2017, 2:44am Hi All, I'm working on Cadence IC616 with UMC40LP technology & using Calibre for DRC. I've encountered following DRC error. POLY1 must be covered by N+ or P+ implant layer Exclude AA_CELL_MARK, HR and MR layers I've turned ON the following switches Since it's a block level Design. DRC UNSELECT CHECK L2_DENSITY // AL_RDL density checking DRC UNSELECT CHECK POLY_DENSITY // PO1 density checking DRC UNSELECT CHECK DIFF_DENSITY // DIFFUSION density checking Follow the attachment for more details..... Please do let me know how to handle this DRC... Thanks in advance... |

You can add/ extend P+ and N+ implant layers between the MOS devices, such that they are touching. This will cover all poly layers by either P+ or N+ implant. |
