关于版图设计时的疑问
以下是版图中四个层次的描述,本人是初学者,不大清楚如何通过这四层去定义n,p管有源区?AA和SP,SN的关系?以以及在做井接触和衬底接触时到底用那一层?哪位热心人能否指点一下,,有没有版图可以发给我看看?谢谢!!
AA: Active Area
AR :Reverse Active Area
SP + implant
SN :N+ implant
Here AA+SP,AA+SN are used for substrate connection, not for diffusions connection of transistors.
Btw,I agree the upper opinion: AA of SMIC is the same as OD of TSMC.
