这个问题需要特别关注一下。
RESP1.16 for sensitive poly resistor,surrounding AA density(including AA dummy),DRC check window size:20um*20um,step size:10um.
DRC check the Marking layer RESSV size up 50um region.
DRC marker layer RESSV is must to draw for sensitive poly resistor ,otherwise,this DRC can not perform on the device.
在90nm 制程之前,遵守design rules可以确保产量在可接受的范围之内。|
However,a lot of challenges to designs due to process variations and reduced yield have resulted in need for several additional recommended design rules for reducing yield loss.So,in addition to the minimum design rules,there are several recommended design rules or guidelines(termed as DFM guidelines) provided for increasing yield and addressing systematic manufacturing issues.
