Dear friends,
I am using the CMOS technology from AMS. it supporting me with four metal layers. except metal 4, I have metal1 and metal 2 and metal 3 having the same via and contact Dimensions. my question is there any different physical properties between them ? I see people are avoiding using higher metalization layers but I don't know why . I only thinking that because metal 3 for example have a deeper via then it has higher contact resistance but I am not sure nor I don't know if might make a difference
Thank you very mmuch
