Seal ring是在芯⽚IO ring 之外的密闭环（所⽤层基本涵盖所有mask layer）；Guard ring通常⽤于电路内部block与block之间的隔离，所⽤层通常是nwell 或psub，或两者⼀同使⽤。（2）.Seal ring（封装条）与Scribe line（划⽚槽）的区别。Scribe line，是把芯⽚从晶圆上切下来的线，是要实际⾛⼑...

从晶圆角度看,seal ring是介于芯片(chip)和划片槽(scribe line)之间的(保护)环。不同的角度,不同的理解,就会有不同得定义,首先来了解下,Seal ring有什么用吧?...Seal ring外有划封线(Scribe line),Scribe line是用来分裂芯片的,为避免造成对内部电路的破坏,所以Seal ring到内部电路有10um距离要求。...在Sc...
